FOREWORD

(This Foreword is not part of ASMElANSl 647.1-1988.)

The original American Gage Design Committee was formed in 1926 to consolidate, for the benefit of industry a t large, the many independent efforts at gage standardization that were in progress at the time.

In March 1930, the standards developed were published as Miscellaneous Publication No. 100 of the National Bureau of Standards, entitled “Plain and Thread Plug and Ring Gage Blanks, Recommended Commercial Standards, ” and were subsequently promulgated by the Department of Commerce as Commercial Standard CS8-30. They were later approved by the American Standards Association (now the American National Standards Institute) as American Standard B47-1932.

The first revision was designated CS8-33 and also approved as ASA B47-1933. A second revision was made in 1940, and a third revision was published as CS8-5 1 effective April 15, 1951. A Supplement was issued to CS8-51 in 1955 and preparation of a fourth revision in supplement form was approved in 1961. It was decided, however, to issue a new document instead of adding another supplement and, in 1961, the American Gage Design Committee, operating undei the guidance of a Chairman, Secretary, Executive Committee, and seven technical subcommittees, prepared the last revision of this document published by the U.S. Department of Commerce as Commercial Standard CS8-61.

In 1962, the American Standards Association accepted the responsibility for distribution and maintenance of the American Gage Design Standard CS8-61, Gage Blanks. The Ameri- can Standards Association designated this standard as ASA B47.1-1962.

U.S.A. Standards Committee B47 was organized and staffed at a meeting held in Dear- born, Michigan, in January 1969. This Committee functions under the new designation American National Standards Committee B47. Seven subcommittees worked on the revision of the B47.1-1962 document.

In 1975, the dial indicator standardization was transferred from the jurisdiction of the B47.1 Standards Committee to that of ANSI Standards Committee B89.

An American Standard implies a consensus of those substantially concerned with its scope and provisions. An American Standard is intended as a guide to aid the manufacturer, the consumer, and the general public. The existence of an American Standard does not in any respect preclude anyone, whether he has approved the standard or not, from manufacturing, marketing, purchasing, or using products, process, or procedures not con- forming to the standard. American Standards are subject to periodic review and users are cautioned to obtain the latest editions. Producers of goods made in conformity with the American Standard are encouraged to state, on their own, responsibility in advertising and promotion material, or on tags or labels, that the goods are produced in conformity with particular American Standards.

A metric translation of B47.1 was issued in 1978. This separate document, B47. lA, con- tained primarily a soft conversion of certain dimensions and tables considered to be most important. It established official metric diameter ranges and gaging lengths for plain and thread plug and ring gages and related handles, plus snap gage ranges. Note that changes made in the 1981 revision of B47.1 automatically superseded the metric dimensions since it is intended that blank lengths, size ranges, and other dimensions be essentially the same

whether expressed in inches or millimeters. Appendix A of that document gives helpful information for converting other inch dimensions into millimeters.

This 1981 revision was approved as an American National Standard by the American National Standards Institute and designated as ANSI B47.1 on March 1981,

A periodic review of this Standard, undertaken by the Committee in 1986, resulted in agreement that the standard be updated to include revision to trilock blanks lightening holes and some of the snap gage anvil screws and snap gage frames in order to make the dimensions standard, as weil as in the agreement that pipe trilock blanks 3.5 in. to 6.0 in. should be the same as smaller trilock in reference to the locking grooves and counterbore.

It was also agreed that the metric supplement, B47. laM, which was published in 1982, be a part of this Standard in the form of an appendix. The intent of the supplement was to establish metric range and gaging lengths for plugs, handles, and snap gage ranges. Dimen- sions are soft conversions.

A proposal containing these and other changes, as well as editorial corrections, was prepared for and balloted by letter ballot to ASME Committee B47. Following approval by ASME, the revised edition was submitted to the American National Standards Institute, and was approved as an American National Standard on February 18, 1988.

GAGE BLANKS

NOTES: (1) While compliance to therevisedspecifications in this document

is urged as soon as possible, the use of blanks and designs in ANSI B47.1-1981 is permissible for a period of 5 years from approval date of this document.

(2) Types of steel or other material for gage blanks and components are not standardized in this document. The typeof material and hardness should be agreed upon by producer and user of the gages.

(3) Certain tables in this document show both nominal thread ranges as well as decimal ranges. In such cases, the decimal range establishes the official dividing line from one blank or handle size to the next.

1 SCOPE

This Standard covers .standard designs for the following:

(a) plain and thread plug gage blanks to 12.010 in. maximum gaging diameter

(b) plain and thread ring gage blanks to 12.260 in. maximum gaging diameter

(c) involute and serrated-spline plug and ring gage blanks to 8.000 in. major diameter (6) straight-sided spline plug and ring gage blanks

to major diameters of 8.000 in. for plugs and 6.000 in. for rings

(e) machine taper plug and ring gage blanks to 5.000 in, gaging diameter

v) adjustable snap gages to 12 in. ( g ) adjustable length gages to any desired length (A) master disks up to 8.010 in. in diameter

Recommended general designs covering taper plug and ring gages for special applications, flush-pin gages, and flat plug gages are also included.

3 DETAILS OF CONSTRUCTION - AMERICAN GAGE DESIGN STANDARDS

3.1 Plain Cylindrical Plug Gage Blanks

3.1.1 Four separatedesigns have been adopted for plain cylindrical plug gages, as follows:

(a) the taper lock design for the range from 0.059 in. to and including 1,510 in.;

(b) the wire type design from 0.010 in. to and including 1.010 in.;

(c) the trilock design with gaging members from above 0.760 in. to and including 8.010 in.; (d) the annular design for the range from above

8.010 in. For sizes above 0.059 in. to and including 8.010 in., bothstraight and progressive gaging members are provided.

3.1.2 WireTypeDesign.Above0.010 in. toand Including 1.01 0 in.

(a) Considerations of convenience and economy have indicated the desirability of having a wire type design of plain plug gage in small diameters. This gage is comprised of a wire type member or members held firmly in a collet type handle of suitable proportions. The gaging member may be extended from the handle a specific amount, as desired, and reversed to increase the useful life of the gage. These gages are available in both single- and double-end types.

(b) Dimensions and tolerances have been established for handles and coilets to accommodate any diameter of plug through the range above 0.010 in. to and including 1.010 in. Lengths for a given range of diameters have been established for the wire type plugs. Details of construction will be apparent from Fig. 1 (pp. 4-5) and Tables 1 through 6 (pp. 6-11).

3.1.3 Taper Lock Design, Above 0.059 in. to and Including 1.510 in.

(a) This type of gage is simple and is economical to produce and maintain. The gaging member has a taper shank that is forced into a taper hole in the handle. When properly assembled, the taper lock gage pos- sesses the rigidity of a solid gage and is entirely free of shake or “wink.” Drift slots or drift holes are provided near the GO end of the handle, permitting gaging members to be removed when replacement is necessary. In the case of double-end gages, the other end is removed by running a.rod through the hollow handle.

(b) Complete dimensionaI tolerances have been established for the mating parts of gaging members and handles, insuring absolute interchangeability of gaging members and handles wherever manufactured. General details of construction will be apparent from a

Fig. 1 (pp. 4-5). See also Tables 7, 8, 10, and 12 (pp. 12, 13, 16, and 18).

3.1,4 Trilock Design, Above 0.760 in. to and In- cluding 8.010 in.

(a) Considerations of rigidity of construction and long life have dictated the trilock design for the size range above 0.760 in. to and including 8.010 in. With this construction there is no chance for shake or wink to interfere with the sensitive feel so necessary in gages of this type. Three wedge-shaped locking prongs on the handle are engaged with corresponding grooves in the gaging member by a single through screw, thus providing a self-centering support with a positive lock, This results in a degree of rigidity equivalent to that of a solid gage. The useful life of the plug, fur- thermore, is materially increased, for when one end is worn the plug can be reversed; it is then, for most purposes, as good as new.

(b) The construction is protected by carefully worked out dimensional limits, and interchangeability is insured between gaging members and handles, wherever manufactured, Details of construction will be apparent from Fig. 1 (pp. 4-5). See also Tables 9, 13, and 14 (pp. 14, 19, and 20).

FIG. 2 PLAIN CYLINDRICAL PLUG GAGES, DETAILS OF CONSTRUCTION -

RANGE ABOVE 8.010 IN.

3.1.5 Annular Design Above 8.010 in. (a) Because of the fact that large plug gages are

heavy and difficult to handle, it was necessary to adopt a design for the range above 8.010 in, that would have the lightest possible section consistent with strength and permanence. The annular design having a rim and web of properly proportioned section, the center being bored out for purposes of weight reduction, has, therefore, been adopted as standard. The web is provided with four tapped holes for convenience in bolting to a face plate during manufacturing. Two of these are further employed for fixing ball handles to the gaging member.

(b) Details of construction have been worked out and are completely dimensioned. See Fig. 2 above and Table 15 (p. 22).

3.2 Handles for Plain Cylindrical and Thread Plug Gage Blanks

(a) Handles for wire type gages are hexagonal with hexagonal collet nuts, and are provided in both single- and double-end types. See Tables 1 through 5 (pp. 6- 10) for details. Handles for the taper Iock types are provided with tapered holes in both ends. SeeTables 7 and 8 (pp. 12-13). Handles for the trilock type gages are provided in both single- and double-end types. See Table 9 (p. 14). Commercial ball handles are employed for the annular plug gage and for certain of the large ring gages. See references in Tables 15, 21, and 35 (pp. 22, 30, and 52).

(b) Handles as designed for all gages offer a feature of economy in that they may be disassembled from gaging members, when the latter are worn out, or dis- carded for any other reason, and then reassembled with new gaging members, thus giving them, with rea- sonable care, practically indefinite life.

(e) Wire type handles and their bushings might vary slightly in design from one gage supplier manufacturer ta another, and shall be considered acceptable as long as they hold the gage member securely.

3.3 Thread Plug Gage Blanks

The wire type, taper lock, trilock, and annular designs have been adopted for thread plug gage blanks and handles. The designs are patterned after the plain cylindrical plug gage bIanks described on pp. 3-20, with the exception that the length of thread gaging members is sIightly different in some instances. The use of taper lock blanks and handles for pipe thread plug gages is standard to and including 2 in. nominal pipe size. General details of construction will be apparent from Fig. 3 (pp. 23-24). Data for thread plug gages are presented in Tables 16 through 21 (pp. 25- 30). Tables 22 and 23, which set forth dimensions of gaging members for fine pitch instrument thread plugs, are given on pp. 3 1-32, and Tables 24 through 26, for thread setting plugs, on pp. 33-35. Tables 27 and 28, specifying handles and gaging members for pipe-thread plug gages, are set forth on pp. 36-37.

(a) The use of the solid ring gage design for size control being well-established, the Committee's work on plainring gages was concerned chiefly with matters of proportion. In the smaller sizes of plain ring gages, a hardened bushing may be pressed into a soft gage body, in place of the one-piece ring gage. This design is optional in the range above 0.010 in. to and incIud-

to facilitate handling. General details of construction are showninFig. 4 (p. 38), and dimensions aregiven in Tables 29 and 30 (pp. 39-40).

FIG. 5 THREAD RING GAGE LOCKING DEVICE, DETAILS OF CONSTRUCTION - RANGE 1 IN. TO 5% IN., INCLUSIVE

3.5 Thread Ring Gage Blanks

(a) The Committee found universal accord as to the superiority of the adjustable thread ring gage over the solid type, with the result that all American Gzge Design Standard thread ring gage blanks are equipped with an effective device for adjusting and locking the gage in the manufacturing or resizing processes. Of the many locking devices considered, the single-unit locking device was finally adopted as standard, as it permits a minimum diameter of blank for a given size

41

range and provides a simple adjustment and positive lock without introducing, into the gage body, any mechanical stresses that might tend to create distortion after setting. Referring to Fig. 5 above, the construction and operation of this device are as follows.

(b) The adjusting screw @ is threaded externally and internally and split longitudinally. Turning this screw to the iight exerts pressure in the sleeve @ against the shoulder in the left-hand side of the gage here shown, thus spreading the ring. Once the ring has


ASME B 4 7 . 1 88

ASME/ANSI 847.1-1 988

been properly adjusted by means of the adjusting screw 0, the adjustment is locked by tightening locking screw @, The tightening of the locking screw 0 exerts a pull between the shoulder, immediately under its head, and the internal threads of the adjusting screw 0, which causes the adjusting screw to expand into the threads in the wall of the gage, the thrust of this action being taken up longitudinally by the sleeve 0. Therefore, the clamping is accomplished by expansion of the adjusting screw equally in all directions and not by the application of any eccentric forces that tend to distort the gage or upset the adjustment. The locking pressure, it is seen, is taken up centrally in the locking screw itself as the reacting support is directly under the head of the locking screw in the form of shoulder in the gage, The sleeve 0, being accurately fitted, serves as a large dowel to maintain the alignment of the gage.

(c) Dimensions for thread ring gage blanks in the range from No. 0 to 12% in., inclusive, and for parts for the thread ring gage locking device, are given in Tables 31 through 38 (pp. 46-56).

(d) Five types of thread ring gage blanks for straight threads have been provided as illustrated in Figs. 6 and 7 (pp. 44-45), namely:

(I) a thin flat disk type with one adjusting slot (two slots optional) for all diameters and pitches, both GO and NOT GO Nos. 0 to 6, inclusive;

(2) a thin flat disk type with two adjusting slots for the following:

(a) all diameters and pitches GO and NOT GO above No. 6 to and including !h in.

(b) fine pitches' GO and NOT GO above '/2

in. to and including 43/4 in. (c) coarse pitches NOT GO only above Y2 in.

to and including 43/4 in. (3) a thick flanged type with two adjusting slots

for all GO coarse pitch gages above 72 in. to and including 4% in.;

(4) a thin flat type provided with ball handles and a plurality of adjusting slots for all fine pitch GO gages and all NOT GO gages in the range above 4.760 in. to and including 12.260 in.;

(5) a thick flanged type provided with ball handles and a plurality of adjusting slots for all coarse pitch GO gages in the range from 4.760 in. to and including 12,260 in.

'Specific information as to the meaning of the terms fine pitches and coarse pitches, as used above, is given in the General Note to Table 32 (p. 49).

GAGE BLANKS

(e) For thread setting and master ring gages, a solid thin flat disk type and a solid thick flanged type are provided in Table 39 (pp. 58-59).

(ß For taper pipe threads a solid flanged type has been provided, as shown in Table 40 (p. 60) for nominal pipe sizes from !h in. to 8 in., inclusive.

3.6 Taper Plug and Ring Gages for Checking Taper

(a) It has been deemed advisable to formulate specifications for a complete set of finished gages for in- specting the taper shanks and handles of gages of taper lock design.

(b) A complete set consists of a taper plug, a taper ring, and a taper check plug for each size range. Gen- eral details of construction will be apparent from Table 41 (p. 62).

(c) The taper limits established by the American National Standards Committee B47 for taper lock handles and shanks may be readily maintained by the use of gages shown in Table 41 (p. 62), in which the taper plug gage is of the single-end limit type, with a ground step representing the minimum size of hole, Equally satisfactory results may be secured by using a single-end taper plug gage, on which a scribed line represents the minimum size of hole and the shoulder of the gage represents the maximum size of hole. Both designs are sanctioned by the American National Standards Committee B47.

3.7 Involute, Serrated, and Straight-Sided Spline Plug and Ring Gage Blanks

The development of standard gage blanks, required for a standard gaging system for involute, serrated, and straight-sided splines, was requested of the Com- mittee. A system of such blanks is presented herein.

(a) The series of blanks for producing gages used in the gaging of internal splines comprises the following.

Spline plug gages and relieved type splineplug gages, with integral handles, for sizes to and including 2 in.

Spline gaging members, pilot fype spline gaging members, and pilot relieved type spline gaging members, with handles for same, for sizes above 1.5 in. to and including 8 in.

Spline tapered tooth plug gages, with either integral or de- tachable handles, for sizes to and including 8 in.

(b) The series of blanks for producinggages used in the gaging of external splines comprises the following.

Spline ring gages and pilot type spline ring gages for sizes to and including 8 in.

Prong type spline relation ring gages in two models, one for space widths greater than 0.070 in. and one for widths of 0.070 in. or less.

Double-end prong type spline alignment ring gages for sizes above 1 in. to and including 6 in.

Built-up double-endsnap gages for tooth thicknesses to and including 0.750 in.

3.8 Machine Taper Plug and Ring Gage Blanks

(a) Taper plug and ring gages for standard machine tapers have been in use for many years. In response to demands for standard designs of gage blanks for Morse, B &S, Jarno, A.S.A., and Series Nos. 10 to 50 milling machine tapers, the Committee has designed gage blanks as follows:

Taper ring gages, with tang, 24 blanks Taper plug gages, with fang, 20 blanks Taper ring gages, without tang, 48 blanks Taper plug gages, without tang, 37 blanks

(b) As useful information but not comprising an essential part of the standard for gage blanks, the finished dimensions of these gages are also tabulated.

(c) Brown & Sharpe tapers as listed in Tables 55 through 58 (pp. 75-85) arenot used inallcases. Brown &Sharpe tapers in No. 4, 5, 7 , 9, 10, and 11 sizes as used for milling machines, milling arbors, shank cut- ters, etc., have different plug depths and different diameters at the end of the sockets. No blank dimensions have been established for these but the essential finished dimensions for these sizes are as follows.

Model A - employing four gaging pins Model B - employing four gaging buttons, either square or

round Model C - employing two gaging buttons, either square or

round, and single block anvil Model MC - a miniature snap gage with two gaging buttons,

either square or round, and a single block anvil

Model E - employing two gaging buttons, either square or round, and a single block anvil extending beyond the gaging buttons

(b) The frames of models A, B, and C have been so designed that common patterns can be used for all three. Frames are of the conventional C or semicircu- lar type, of cast iron with solid web. Particular atten- tion was given to weight, which approximated the average of former proprietary designs.

(c) The straight gaging pins are of circular cross section, an arcuate bevel being provided at the front edge where they first engage the work. The flanged gaging buttons are provided with either square or circular heads, the former being chamfered on their for- ward edges, and the latter being provided with an arcuate bevel where they first engage the work. The gap between GO and NOT GO has been kept to a minimum. (d) Alocking device was adopted that has stood the

test of time - the three-piece type with two flats on the shank of the gaging button or pin, and a locking nut and locking bushing, each provided with a bevel flat.

The design adopted incorporates the following: ( I ) adesign of frame that has proved to be excep-

(2) reduction of weight to as low a point as

(3) distribution of metal to assure a nice balance

(4) an effective and proved locking device; (5) suitable construction of gaging pins, but-

tons, and anvils to give ample rigidity and maintain accuracy;

3.1 0 Adjustable Length Gages

(a) The American Gage Design Standard adjustable length gage employs, for gaging members and adjusting and locking means, the same fittings that are utilized in adjustable snap gages, as detailed in Table 74 (p. i l l ) .

(b) The gage heads are designed in two models, as follows:

( I ) the double-sided model with GO and NOT GO gaging members on opposite sides of the spacing tubes;

(2) the progressive model with two pairs of gaging members on the same side of the spacing tubes. Ail models may be used to cover a very wide range, as the spacing tubes may be constructed in any length desired. See Table 73 above.

(c) General details of construction and dimensions are shown in Figs. 13 through 19 (pp. 104-110).

3.1 1 Thread Snap and Indicating Thread Gages

(a) Thread Snap Gages. Thread snap gages are usually adjustable and are comprised of a U-shaped frame on which are mounted one or two pair of gaging elements - one pair for checking GO (maximum- material limit), the second pair for checking NOT GO (minimum-material limit). These gages most commonly are made to check external product threads and, as such, are usually set to conventional thread setting plug gages.

(6) Indicating Thread Gages. Indicating thread gages usually comprise a frame with an arm on which are mounted one or more pairs of gaging elements and means for registering the variation of movement on a dial indicator or other means. These gages are usually set to conventional thread setting gages.

(c) There are no American Gage Design standards at present for thread snap or indicating thread gages. Various types are in general usage and no attempt is made to pass judgment on or standardize any particular designs. This paragraph is inserted in this document to establish recognition of these gages and their relationship to other types of gages. Possibly some details of the designs can be standardized in future revi- sions of this Standard.

The optional use of the monogram shown in Fig. 22 to identify gages made to American Gage Design Standards is sanctioned by the Committee. Themono- gram, it will be noted, consists of the initials “AD,” the right-hand side of the “A” and the straight side of the “Dy’ being common. The monogram, if used, should be placed adjacent to the maker’s trademark,


5 APPLICATION OF AMERICAN GAGE DESIGN

RECOMMENDED PRACTICE

(a) WhiIe the American Gage Design Standards have been adopted with specific types and sizes of gages in mind, it is recommended that standard blanks, handles, etc., be used wherever practicable in the design and manufacture of special gages, the design of which does not come within the scope of the Committee’s work.

(b) Where lengths and diameters are entirely special and blanks of standard dimensions cannot be utilized, it is further recommended that standard handles and fittings be used.

(c) Observance of the practices in (a) and (b) above will tend to reduce costs and facilitate procurement.

(a) There are many commonly used gages that are not adaptable to detailed standardization, but that can be classified, to advantage, as to types or general designs. A number of these have been considered, and it is recommended that the general constructions out- lined in Figs. 23 through 26 (pp. 121-124) and Table 84 (p. 126) be adhered to whenever practicable.

STANDARDS TO SPECIAL TYPES OF GAGES -

119


A S M E 847.1 88 m 0759670 004bb37 9 m


6 FLUSH PIN GAGES

(a) There are many and varied types of flush pin gages in use throughout industry. Although each gage is designed to fit a particular application, the body of the gage fits one of several basic design patterns in the greater majority of cases.

(b) Because of the wide use of this type of gage, some expansion to the previous design was in order, and several recommended styles with dimensions are practical for the different size ranges. It was felt that this would be a benefit to both users and suppliers.

(c) Four variations of style were adopted. These are illustrated in Table 83 (p. 125) and Figs. 25, 26, and 27 (pp. 123-127) as follows.

( I ) Style 1 - the barrel type with pin diameters ranging from 0.250 to 0.750 (shown in Table 83).

(2) Style 2 -the bar type with bar lengths in 2 in. increments. While the 7/i6 diameter pin seems the most common and thus shown as the standard, other pin diameters can be supplied according to application requirements as defined by the user (shown in Fig. 25).

(3) Styles 3A and 3B - the bar spanner and bar countersink type, being applicable for countersink depth dimensions or for depth dimensions where a straight pin will not reach (shown in Figs. 26 and 27). Figure 28 was added to illustrate a countersink application of the gage. (d) The illustrations show the gaging step to be

ground on the pin as this represents the more conven- ient and less expensive method of manufacture, and thus will be considered the standard method of com- pleting those gages whose pin diameters are greater than 0.282 diameter. Gage users who prefer that the step be ground on the gage body should so specify when ordering. Gages having a pin diameter of 0.282 diameter or smaller will normally have the step ground on the body to facilitate greater efficiency of usage.

7 DOUBLE-END BUILT-UP SNAP GAGES

(a) Because built-up snap gages are always designed to fit special applications, they are not readily adaptable to detailed standardization. As a means of affording some measure of cost savings, however, the Committee has expanded the recommended design to cover two size ranges and has revised the dimensioning to provide greater applicability,

(b) Figure 29 (p. 128) shows the recommended dimensions for gages in the measuring range of 0.000 to

120

GAGE BLANKS

0.250, and Fig. 30 (p. 128) shows the dimensions for gages in the measuring range of above 0.250 to 1 .OOO.

(c) The Committee would like to point out that while it is imperative that the upper and lower jaws be hardened, the center piece or spacer seldom needs to be hardened. Recommended material for the spacer is either mild steel or tool steel left soft. Cold rolled steel should never be used due to its instability.

8 FLAT PLUG GAGES

(a) The recommended design for flat plug gages is shown in Table 84 (p. 126) and Table 85 (p. 129), which indicates the gage thickness for the various size ranges. The thicknesses shown provide for the manufacture of blanks from available standard thicknesses of heat treatable flat ground stock. Aprogressive plug member is illustrated so as to include sufficient dimensioning to cover all gage types and applications.

(b) Recognizing that flat plug gages will perhaps be more often used as single-end NOT GO gages as a means of detecting oversize conditions where out-of- roundness exists, and when used as such, as weil as in other applications, a handle would be highly desirable, the Committee has added a second illustration showing the additional dimensioning required to provide the threads and locking grooves necessary for handle attachment. A table accompanies this second illustration to show the thread and screw sizes for the two size ranges. Note that the dimensioning is such that the same tooling used for trilock gages can be used for the bilock design here recommended.

(c) It should be recognized that the addition of the provisions for the attachment of a handle adds an additional cost to the manufacture of the gage blank, and that in many applications the handle will not be a definite advantage. Gages, therefore, will be furnished with such provisions only specified by the user.

9 HANDLES, BILOCK, FOR FLAT PLUG GAGES

Handles for flat plug gages, as illustrated in Table 85 (p. 129), are of the bilock typ.e with the configura- tion of the locking lugs developed so that manufacture can be accomplished using the same tooling as is used in the manufacture of trilock handles. These handles are hexagonal, and for the present are designed only for single-end application.

APPENDIX A

CONVERSION TABLE FROM INCH TO MILLIMETER

(This Appendix is an integral part of ASMEIANSI 647.1-1 988 and is placed after the main text for convenience.)

Any dimension in this Standard can be converted by the addition of its components from the tables in this Appendix.

Consider the actual or implied precision of the values in customary units in determining the number of significant digits to be retained in the SI equivalents. (For an explanation of conversion techniques, see American National Standard Metric Practice, ANSI/ IEEE 268-1982.)

APPENDIX B

METRIC EQUIVALENTS OF SELECTED TABLES

(This Appendix is an integral part of ASMElANSl 847.1-1 988 and is placed after the main text for convenience.)

The information in this Appendix establishes official metric diameter ranges and gaging lengths for plain and thread pIug and ring gages and related handles, plus snap gage ranges. These are primarily soft conversion dimensions and will serve as a guide for metric conversions of other dimensions and tables in this Standard.

Reference is made to table numbers and pages of this Standard. This Appendix should serve to establish uniformity of metric gaging lengths, size ranges, etc. , for gage drawings, catalogs, and other literature.
