Indian Standard SPECIFICATION FOR HEALD WIRE

0. FOREWORD

0.1 This Indian Standard was adopted by the Indian Standards Institution on 15 September 1977, after the draft finalized by the Wrought Steel Products Sectional Committee had been approved by the Structural and Metals Division Council.

0.2 Steel heald wire is a very high quality, high carbon steel wire used for the manufacture of that part of the harness on a weaving loom known as the heald. The healds serve as a means for alternately lowering and raising the warp threads of the fabric being woven in order to permit the free travel of shuttle of the loom. The warp threads are carried by the central eyes formed in the healds and the healds are attached to the harness by means of the loops formed in their ends.

O.Z-1 The first step in making flat healds is rolling of round wire while that for wire heald is twin tinning of drawn wires. Both the processes involve severe cold work that required steel of superior surface internal soundness and chemical uniformity land also require closely controlled wire mill processing. These precautions are necessary so that the finished healds will not injure the threads of fine fabric.

0.3 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accor- dance with IS : Z-1960*. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

1. SCOPE

1.1 This standard covers the requirements of round steel wires for heald for the following purposes :

a) Healds for jacquard harness;

b) Healds for dobby harness;

c) Inset mail wire healds for jute weaving;

“Rules for rounding off numerical values ( reoised ),

IS : 8565 - 1977

d) Gontact wire healds for jute weaving; e) Healds for cotton, silk, woollen and worsted weaving; and

f) Twin wire healds used for frame weaving.

2. SUPPLY OF MATERIAL 2.1 The general requirements relating to the supply of steel wire shall be as laid down in IS : 1387-1967”.

2.2 The wire may be supplied in the following conditions:

a) Hardened and tempered; and

b) Patented and drawn.

3. MANUFACTURE

3.1 The wire shall be drawn from steel manufactured by open-hearth, electric duplex, basic oxygen or a combination of these processes. In case any other process is employed by the manufacturer, prior approval of the purchaser should be obtained.

3.2 Sufficient discard shall de taken to ensure freedom from injurious pipe and seggregation.

4. CHEMICAL COMPOSITION

4.1 The ladle analysis of steel when analysed in accordance with the relevant part ~of IS : 2287 shall be as given below :

Constituents, Percent r----------- ---_A-_-------_---,~

C Si P S 0.35-0.70 0.E. 70 0.10-0.35 0.04 0.04

NOTE-Restricted carbon ranges may be agreed upon if required at the time of enquiry and order.

4.2 Product Analysis - The permissible variation in the case of product analysis from the limits specified in 4.1 shall be as follows :

Constituent Permissible Variation, Percent

Carbon & 0.04 Manganese f 0.04 Silicon 4 o-03 Phosphorus + 0.005 Sulphur + 0.005

NOTE -Variations shall not be applicable both over and under the specified limits in several determinations in a heat.

5. SIZES AND TOLERANCES

5.1 The wire shall be supplied in the following sizes :

0.25, 0.30, O-40, 0.55, O-60, 0.70, 0.80, 1.0, 1.17, 1.32 mm

5.2 The wixes may be supplied in other sizes also as agreed to between the purchaser and the manufacturer.

5.3 Tolerances on diameter shall be l-5 percent with a minimum of f 0.015 mm.

5.3.1 The cross section of the round wire shall be circular to within l/2 the tolerances of the permitted diameter tolerances.

6. TENSILE TEST

6.1 Tensile Strength - When tested in accordance with IS : 1521-1972*, the material shall have the followingtensile strength :

Hardened and tempered 1 100 N/mmz, Min

Patented and drawn a) 1 300 to 1 700 N/mm2 b) 1 600-2 000 N/mm2

7. DEAD WIRE TEST

7.1 Hardened and Tempered Wire -The wire shall pay off straight.

7.2 Patented and Drawn - The wires shall be as straight as possible * without any cork screw effect.

8. CONDITION OF DELIVERY

8.1 The wire shall be generally supplied in coils. The weight of the coil shall be mutually agreed to between the purchaser and the manufacturer.

9. SAMPLING

9.1 Unless otherwise agreed to, the method of drawing representative samples of the material and the criteria for conformity shall be as prescribed in Appendix A.

10. PACKING AND MARKING

10.1 The wire shall be supplied in the oiled condition/unoiled condition with suitable packing as agreed to between the purchaser and the manufacturer.

IS : 8565 - 1977

10.2 Each coil of wires shall be bound compactly and shall have a tag Icgibly marked with the following :

a) Name or trade-mark of the manufacturer,

b) Type and size of wire,

c) Lot number, and

d) Mass of coil.

10.2.1 The coils may also be marked with the IS1 Certification Mark. NOTE -The use of the IS1 Certification Mark is governed by the provisions of

the Indian Standards Institution (Certification Marks) Act and the Rules and Regulations made thereunder. The IS1 Mark on products covered by an Indian standard conveys the assurance that they have been produced to comply with the requirements of that standard under a well-defined system of inspection, testing and quality control which is devised and supervised by IS1 and operated by the producer. IS1 marked products are also continuously checked by IS1 for conformity to that standard as a further safeguard. Details of conditions under which a licence for the use of the IS1 Certification Mark may be granted to manufacturers or processors, may be obtained from the Indian Standards Institution.

APPENDIX A ( Clause 9.1 )

SAMPLING AND CRITERIA FOR CONFORMITY c

A-l. LOT

A-l.1 In any consignment, all the coils of wire of the same grade and diameter manufactured under essentially similar conditions of manufacture, shall be grouped together to constitute a lot.

A-1.1.1 Samples shall be taken from each lot and tested for conformity to the standard.

A-2. SAMPLING

A-2.J The number of coils to be taken from a lot shall be according to co1 1 and 2 of Table 1. These samples shall be taken at random by using number tables ( see IS : 4905-1968” ).

A-3. PREPARATION OF SAMPLES AND NUMBER OF TESTS

A-3.1 Tests for Physical Requirements--From the coils selected according to co1 1 and 2 of Table 1, adequate length of test piece shall be cut from each end and subjected to physical tests, namely, size, surface ~______~___

*Methods for random sampling.

condition, tensile and dead wire test. A test piece failing to meet any one of the requirements, shall be called a defective. If the number of defec- tives found is less than the number of permissible number of defectives specified in co1 3 of Table 1, the lot shall be considered to have conformed to physical requirements otherwise not.
