SECTION IINTRODUCTION

l-l. Purpose. This bulletin provides the basic infor-mation and detailed inspection procedures requiredto determine the serviceability status of alarms,chemical agent, automatic and ancillary items.

l-2. Scope. The provisions of this bulletin aremandatory for use in conducting all types ofsurveillance inspection, as identified in this bulletin,on the chemical materiel listed by National StockNumber (NSN) in appendix A. The provisions applyonly to Department of the Army depots and todepot activities.

l-3. Definitions. a. Commonly Used QualityAssurance Terms. Refer to MIL-STD-109 fordefinitions of these terms.

b. Specialized Terms. The following definitions arein alphabetical order by major heading. They applyto specialized terms used in this bulletin.

(1) Codes. Numbers and letters used for brevity.(a) Inspection Fequency Code (IFC). A

numeric code to tell how often to perform inspectionof materiel in storage. The numeric codes and defini-tions are listed in paragraph Z-6e.

(b) Quality Defect Code (QUAL DEF CODE).A numeric code assigned to indicate the category ofa given defect and to identify, by explanation, thatparticular defect. The coding system and definitionsare enumerated in paragraph 2-6a

(c) Shelf-Life Code (SLC). A code assigned to ashelf-life item. The code identifies a period of timethat starts with the date of manufacture orassembly and ends when the item must be issued orbe subjected to inspection, restoration, or todisposal action (AR 700-89). The codes andassociated times are listed in paragraph 2-6d.

(d) Test Required Code (TRC). A three-digitnumeric-alpha code that is used in appendix A to in-dicate that only a simple examination is required(QUAL DEF CODES) or to cross-reference addi-tional inspection requirements. The code meaningsare in paragraphs 2-6a and 2-Sfi

(2) Corrosion, metals. See paragraph 2-6a(3)Ij).Stage I (Defect Code 99). Discoloration or

staining with no direct visual evidence of pitting,etching, or other surface damage.

Stage II (Defect Code 91). Red, brown, green,black, or white corrosion product accompanied byminor etching or minor surface pitting. No scale ortight rust.

Stage III (Defect Code 92). Red, brown, green,black, or white corrosion product with or without

etching, pitting, or more extensive surfacedeterioration resulting in a loose or granular condi-tion.

Stage IV (Defect Code 93). Red, brown, green,black, or white corrosion progressed to the pointwhere fit, wear, function, or life of the item has beenaffected. Powdered or scaly condition with pits or ir-regular areas of material removed from the surfaceof the item.

(3) Defect number. A number associated with aparticular defect. It identifies the defect and theseverity of the defect. The numbers are used inparticular classification of defects tables. The defectdesignated by a number is not permanent such as inquality defect codes ((l)(b) above) but is redefined ineach table where the number is used, although oftenthe definition will closely parallel a quality defectcode definition. Sequential numbers starting with 0are critical defects; sequential numbers startingwith 101 (1Xx) are major defects; and sequentialnumbers starting with 201 (2Xx) are minor defects.

(4) Deterioration. A change in an item’scharacteristics caused by an environment thatadversely affects its ability to function as intended.See paragraph 2-6a(3&).

(a) Deterioration, polymeric plastic items.Molded organic compounds: celluloid, bakelite,lucite, vinyl, rubber, etc.

Stage I (Defect Code 94A). Fungus damage,color change, or distortion.

Stage II (Defect Code 94B). Sticky surface,craze cracks, dissolved paint, or small cracks.

Stage III (Defect Code 94C). Liquifiedmaterial, large cracks, crumbled (brittle), or frac-tured (broken) to an extent where fit, function, or lifehas been affected.

(b) Deterioration, polymeric non-plastic items.Non-molded organic components: cloth, leather,hair, fur, felt, paper, cork, cardboard, wood, etc.

Stage I (Defect Code 95A). Mold, fungusdamage, or color change.

Stage II (Defect Code 95B). Shredding,warping, shrinkage, distortion, embrittlement,small separations (cracks or tears), or slight swell-ing.

Stage III (Defect Code 95C). Gross swelling,soggy, large cracks, rot, insect infestation. brittledisintegration, or large or complete separations toan extent where fit, function, or life has beenaffected.

SB 740-94-3

(c) Deterioration, inorganic vitreous items.Glass, ceramic, solid carbon, etc.

Stage I (Defect Code 96A). Small cracks orcrazed (crackled surface).

Stage II (Defect Code 96B). Spalling (chip-ped) or fractured (broken, major cracks, or splits) toan extent where fit, function, or life has beenaffected.

(5) Inspections (types of).(a) Cyclical Inspection (CR. Surveillance of

material in storage performed on a regular basis. Inthis bulletin, the cycle is established in appendix Aby the Inspection Frequency Code (IFC-see para-graph 26e). The purpose is to determine the service-ability status of items at the end of each cycle.

(b) Initial Receipt Inspection (IR). An inspec-tion performed on newly manufactured materielreceived directly from a vendor, manufacturer, orgovernment activity. The purpose is to determine ifthe items, the packing, or the preservation havebeen damaged in transit and whether the packaging,marking, and preservation are correct. This inspec-tion is not intended as an acceptance-type inspec-tion.

(c) Pre-Issue Inspection (PI). The inspectionsand tests on materiel immediately preceding issue.

(d) Prestorage Inspection (PS). An inspectionperformed on materiel received from other depots,posts, camps, stations, or overseas returns receivedwithin CONUS. The purpose is to determine receiptcondition and the current degree of serviceability ofthe items when serviceability status is unknown.

(e) Special Inspection (SI). An inspection per-formed at the direction of higher headquarters or asdeemed necessary to satisfy local installationrequirements.

(fl Unit Basis Inspection (III). An inspectionwhere each unit in the lot is inspected for the defectcharacteristic under consideration. The unit basismethod is also used for serially-numbered major enditems that are considered separately for surveillancepurposes.

(6) Lots.(a) Depot lot. A combination of lots of the

same kind and type of materiel grouped into onelarge single lot for the purpose of economy insurveillance.

(b) Grand lot. All lots of the same kind andtype of materiel from one manufacturer or recondi-tioning agency grouped into one large lot for thepurpose of economy in surveillance.

(c) Manufacturer’s lot. A quantity of one itemof materiel manufactured or assembled in one plant,

from raw materials or components of the samephysical characteristics, under uniform conditionsdesigned to effect homogeneity, and meetingdefinite physical and chemical requirements ofestablished specifications and drawings (this in-cludes renovated, reworked, and reconditioned lots).

(d) Miscellaneous lot. A combination of asingle manufacturer’s small lots or lot fragmentspossessing the same technical history.

(e) Mixed lot. A combination of the same kindand type of materiel for which identification of themanufacturer, and lot number, or the time ofmanufacture is incomplete.

(7) Occurrence basis. An inspection, without apredetermined time frame, that is performed as theneed occurs, e.g., initial receipt inspection (IR) isperformed when the shipment arrives.

(8) Serviceable. The condition of an item thathas been determined by inspection to be satisfac-tory and safe for its intended use.

(9) Shelf-life item. An item of supply possessingdeteriorative or unstable characteristics to thedegree that a storage time period must be assignedto assure that it will perform satisfactorily in ser-vice. There are two types of shelf-life items:

(a) Type I shelf-life item. An item of supplythat is determined, through an evaluation of techni-cal test data or actual experience, to be an item witha definite non-extendable shelf life.

(b) Type II shelf-life item. An item of supplyhaving an assigned shelf life, where the shelf lifemay be extended after the completion of a prescribed inspection or a restorative action.

(10) Storage Serviceability Standards (SSS).Technical documents containing inspection instruc-tions and criteria essential to determine service-ability of materiel in storage.

(11) Unserviceable. The condition of an itemthat has been determined by inspection to be un-satisfactory or unsafe for its intended use.

Additional references peculiar to a givengroup of alarms, chemical agent, automaticand ancillary items will be cited in theappendix for the group of items.

2-2 Safety. During surveillance and normal han-dling (TM 743-200-l) of alarms, chemical agent,automatic and ancillary items, inspection personnelshall observe the safety precautions prescribed foroperations personnel, the safety precautions cited inapplicable regulations, FM 3-9, TM 3-220, TM3-250, technical manuals describing the materiel,and special safety precautions cited in the appli-cable appendix of this bulletin.

2-3. Lotting. a. Type of Lotting Permitted. The ap-plicable appendix of this bulletin specifies the typesof lotting permitted when conducting surveillance ofthe alarms, chemical agent, automatic and ancillaryitems.

b. Depot Lot. A depot lot is formed by combininglots into a large single lot. Actual formation is apaper transaction; regrouping and marking of themateriel is not required. A depot lot, as such, cannotbe declared unserviceable. When, through surveil-lance, a lot within the depot lot appears unservice-able, withdraw the lot concerned and take additionalsamples by the sampling plan provided in this bulle-tin. If the suspect lot is found serviceable, it remainsa part of the depot lot. If the suspect lot is foundunserviceable, the lot is eligible for rework ordisposal by existing regulations. When 20 percent ofthe lots within the depot lot have become unservice-able, the depot lot shall be dissolved and the in-dividual lots therein tested on a lot-by-lot basis. Adepot lot must meet criteria as follows:

(1) Kino!, type, and model. All items must be thesame kind, type, and model.

(2) Storage. All items must be stored undersimilar conditions at the same depot.

(3) Serviceability status. All lots must possessthe same serviceability status, i.e., serviceabilityknown (based upon prior surveillance) or service-ability unknown. However, when new procurementis involved, base serviceability on acceptance in-spection, not on surveillance.

c. Grand Lot. A grand lot is formed by combing alllots from one manufacturer into a large single lot.Actual formation is a paper transaction, regroupingand marking of the materiel is not required. A grandlot, as such, cannot be declared unserviceable.When, through surveillance, a lot within the grandlot appears unserviceable, withdraw the lot concern-ed and take additional samples by the sampling planprovided in this bulletin. If the suspect lot is foundserviceable, it remains a part of the grand lot. If thesuspect lot is found unserviceable, the lot is eligiblefor rework or disposal by existing regulations. When20 percent of the lots within the grand lot havebecome unserviceable, the grand lot shall be dis-solved and the individual lots therein tested on a lot-by-lot basis. A grand lot must meet criteria asfollows:

(1) Kind, type, and model. All lots must be thesame kind, type, and model.

(2) Manufacture. All lots must be the product ofthe same manufacture or reconditioning agency.

2 - l

SB 740-94-3

(3) Preservation and packaging. All lots musthave the same type preservation, packaging, andidentification markings.

(4) Storage. All lots must be stored undersimilar conditions at the same depot.

(5) Serviceability status. All lots must possessthe same serviceability status, i.e., serviceabilityknown (based) upon prior surveillance) or service-ability unknown. However, when new procurementis involved, base serviceability on acceptance in-spection not on surveillance.

d. Manufacturer’s Lot. A manufacturer’s lot con-sists of those items manufactured or assembled byone manufacturer or reconditioning activity andbearing the same manufacturer’s or reconditioningagency’s lot identification number. The manufac-turer’s lot must meet criteria as follows:

(1) Preservation and packaging. All items musthave the same type preservation, packaging, andidentification marking.


(3) Serviceability status. All items must possessthe same serviceability status, i.e., serviceabilityknown (based upon prior surveillance) or service-ability unknown. However, when new procurementis involved, base serviceability on acceptance in-spection not on surveillance.

e. Miscellaneous Lot. A miscellaneous lot is form-ed by combining a single-manufacturer’s lots or lotfragments into one lot. The size of miscellaneouslots is restricted by the applicable appendix of thisbulletin. Actual formation of the lot is a paper trans-action, regrouping and marking of the materiel isnot required. A miscellaneous lot may be declaredunserviceable as a whole. The miscellaneous lotmust meet criteria as follows:

(1) Kind, type, and model. All items must be ofthe same kind, type, and model.

(2) Manufacturer. Each small lot or lot fragmentmust be the prodclct of the same manufacturer or re-conditioning agency.

(3) Preservation and packaging. All items musthave the same type preservation, packaging, andidentification marking.


(5) Serviceability status. All items must possessthe same serviceability status, i.e., serviceabilityknown (based upon prior surveillance) or service-ability unknown. However, when new procurementis involved, base serviceability on acceptance in-spection not on surveillance.

$ Mixed Lot. A mixed lot is formed by combiningthose items with incomplete identification into onelot. The size of the mixed lot is restricted by the ap-plicable appendix of this bulletin. Actual formationof the lot is a paper transaction, regrouping and

marking of the materiel is not required. A mixed lotmay be declared unserviceable as a whole. Themixed lot must meet criteria as follows:

(1) Kina?, type, and model. All items must be ofthe same kind, type, and model.

(2) Preservation and packaging. All items musthave the same type preservation and packaging.


2-4 Sampling. Sampling for alarms, chemical agent,automatic and ancillary items shall be performed bythis paragraph and the instructions provided. in theapplicable appendixes of this bulletin. The samplinginstructions that follow are designed to fit thepeculiarities of this group of items. In some in-stances, special sampling designed for an itemwithin a group may be required. This may be re-quired by the configuration, short shelf life, or pastquality history of the item.

a. Initial Receipt Inspection (IR). sampling shallbe conducted in accordance with this paragraph andMIL-STD-105, Inspection Level S4, AQL of 4.0percent for Major defectives, and 6.5 percent forMinor Defectives.

b. Prestorage Inspection (PS). Sampling shall beconducted in accordance with this paragraph andMIL-STD-105, Inspection Level S4, AQL of 4.0percent for major defectives, and 6.5 percent forMinor Defectives.

c. Cyclical Inspection (CT). Sampling shall be con-ducted in accordance with this paragraph andMIL-STD-105 using the Inspection Level and AQLspecified in appendix A or the sampling instructionsprovided in the applicable appendix (TRC) of thisbulletin for the item being sampled. In some in-stances, special sampling designed for an itemwithin a group may be required. This may be re-quired by the configuration, short shelf life, or pastquality history of the item.

d. Pre-Issue Inspection (PI). Sampling, if required,(see para 2-5d(2)) shall be conducted by c above. ’

e. Selection of samples.(1) All portions of the lot must be located for

sampling.(2) Every reasonable effort must be made to ob-

tain a random sample. When conditions make a pro-per random sampling impossible, record this factand a brief description of the condition thatprevents random sampling under the remarks sec-tion Part I, Block 20, DA Form 984 (Munitions Sur-veillance Report). See paragraph 2-9a(l), Part I (s),of this bulletin.

(3) In selecting samples from depot lots, grandlots, or miscellaneous lots, choose the items to repre-sent all material. For example, if a manufacturer’slot is one-third of the, total lot, then select one-thirdof the lot sample at random from thatmanufacturer’s lot.

l

f Sample Disposition.(1) In the inspection records, identify as

reinspected, all samples that have been inspectedand then packed and resealed in barrier material.

(2) Reseal barrier material by the instructionsfurnished with the material, printed on the material,or furnished with the sealing iron.

(3) Return serviceable samples to storage withthe parent lot.

(4) Segregate samples with critical or majordefects or samples that cannot be returned to theoriginal package configuration and report such inthe remarks section, Part II, Block 13 of DA Form984 (Munitions Surveillance Report). See paragraph2-9a(l), Part II(h) of this bulletin.

SB 740-94-3

2-5. Inspection. Conduct all inspection and testsunder the control of a qualified inspector. The in-spections and tests normally will be conducted atthe surveillance inspection area; however, whenauthorized, examinations or test may be performedat the storage site or elsewhere, but must be withinthe limitations of all safety and security re-quirements.

a. Initial Receipt Inspection (IR).(1) Frequency. Perform this inspection on an oc-

currence basis [see para l-3b(7)].(2) Classification of defects. Use table 2-l to

acids, compressed gasses, or radioactive).U Open space (materiel may be stored in open storage).Y Storage space for ammunition items (Class V) covered

by specific regulations elsewhere.2 A storage environment identified by one of the codes is

not necessary. See AR 740-l for guidance.

2-7. Evaluation. a. Serviceability Based on SamplingInspection. A lot shall be classified as serviceable pro-vided no critical defect is observed and the number ofmajor and minor defects does not exceed the numberallowed in the sampling plan for the item.

b. Serviceability on Unit Basis Inspection. A nitem inspected on a unit basis, or subjected to 100percent inspection, is serviceable if the followingcriteria are met:

(1) No defects are observed.(2) All requirements for test or analysis are met.(3) All units have been modified to existing

Modification Work Orders (MWO’s).c. Special Instructions. In addition to criteria for

evaluation contained in this paragraph, specialcriteria for certain items or groups of items are pro-vided, when necessary, in the applicable appendixesof this bulletin.

d. Procedure for Rounding Off. Numerical re-quirements, when stated, indicate the number ofsignificant digits to be retained, i.e., the last figureor decimal place to be reported. The procedure givenbelow is to be used in rounding off observed orcalculated values for the purpose of evaluation.

(1) When the first digit dropped is less than 5,the preceding digit is not changed. When the firstdigit dropped is greater than 5, or 5 and some suc-ceeding digit is not zero, the preceding digit is in-creased by 1. When the first digit dropped is 5, andthere are no succeeding digits or all succeedingdigits are zero, add 1 to the preceding digit if it isodd and leave it unchanged if it is even.

(2) Examples when rounding to two decimalplaces:

2.3142 = 2.31 The first digit dropped is less than 5-leave preced-2.3249 = 2.32 ing digit unchanged regardless of any succeeding

digits.2.3150 = 2.32 The first digit dropped is exactly 5, or 5 followed2.3250 = 2.32 zeroes-add 1 to the preceding digit if it is odd

and leave it unchanged if it is even.2.3152 = 2.32 The first digit dropped is 5 followed by other than2.3252 = 2.33 zeroes-add 1 to the preceding digit.2.3160 = 2.32 The first digit dropped is greater tan 5-add 1 to2.3260 = 2.33 the preceding digit regardless of any succeeding

digits.

The sample of itemslisted in paragraph B-l shall be visually inspectedfor packaging, packing, marking, and preservationdefects as identified in the classification of defects,table B-l. The end item or components thereof shallbe visually inspected for defects listed in the ap-plicable classification of defects talbe B-2 throughB-l 1. The required sample size for test, of visuallyacceptable items, shall be subjected to the testsdescribed in c below, as applicable. Tables B-2through B-4 and B-8 through B-11 is addition toproviding classification of visual defects, providesclassification of test failures. The classification oftest failures is provided to differentiate between thetest failures to be considered as critical, wherein oneitem failing the test would be cause for immediatelysuspending the lot from issue and use, and the testfailure to be considered as major, wherein accept-ance or rejection of the lot would be based on the ac-ceptance number of the sampling plan.

NOTEThe classification of defect tables in addi-tion to providing classification of visualdefects, provides classification of test(s)failures. The classification of test(s) failuresis provided to differentiate between the testfailures to be considered as critical, whereinone item failing the test would be cause for

immediately suspending the lot from issueand use, and the test failures to be con-sidered as major, wherein acceptance or re-jection of the lot would be based on the ac-ceptance number of the sampling plan.
