Indian Standard SPECIFICATION FOR
NYLON FABRIC FOR SLEEPING BAGS
0. FOREWORD
0.1 This Indian Standard was adopted by the Indian Standards Institution on 15 December 1978, after the draft finalized by the Silk, Man-Made Fibre and Products Sectional Committee had been approved by the Textile Division Council.
0.2 The nylon fabric covered by this standard is intended to be used for manufacturing sleeping bags by the Defcnce personnel.
0.3 To familiarize the industry with International System of Units ( SI Units ), the basic SI Units as well as the recommended SI Units for use in the textile industry are given in Appendix A.
0.4 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 accordance 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 prescribes the requirements for coated or treated nylon fabric used in the manufacture of sleeping bags for use as mountaineering equipment or for use on high altitudes.
2. MANUFACTURE
2.1 Yarn - Continuous filament medium tenacity nylon yarn of type
6 shall be used in the manufacture of the cloth.
2.2 Cloth - The cloth shall be woven uniformly and evenly in plain or
ripstop weave. The selvedges shall have the same tension as the remainder of the fabric and shall not be unduly thicker than the fabric. The selvedges shall not fold on themselves nor present a corded edge effect. The fabric shall be coated or treated with suitable chemicals so that the water resistant characteristic is imparted to it. The fabric shall be given a nip-calender finish.
*Rules for rounding off numerical values ( raoiscd ).

4. MARKING
4.1 Each roll of fabric shall be marked with the following:
a) Name of the material;
b) Manufacturer’s name, initials or trade-mark, if any;
cl Length x width ofroll; and
4 Date of manufacture.
4.1.1 Mark.
The fabric may also be marked with the IS1 Certification
NATE - The use of the ISI 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. ISI 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.
5. PACKING
5.1 The fabric shall be packed in roll form in accordance with the
provisions of IS : 2195-1964* or IS : 2194-1963t, as the case may be.
6. SAMPLING
6.1 Lot - The quantity of nylon fabric delivered to a buyer against a despatch note shall constitute a lot.
NOTE - The sampling plan given below shall give desired protection to the buyer and the seller provided the lot submitted for inspection is homogeneous. To ensure homogeneity of the lot, it is recommended that the manufacturers should follow the methods given in IS : 397 ( Part I )-1972$ and IS : 397 ( Part II )-1975$.
6.2 The conformity of the lot to the requirements of this standardshall be adjudged on the basis of the tests carried out on the samples selected from it.
6.3 Unless otherwise agreed to between the buyer and the seller, the number of rolls or pieces to be selected from a lot shall be in accordance
with co1 1 and 2 of Table 2.
*Code for inland packaging of man-made fibre fabrics and man-made fibre yarns. tCode for seaworthy packaging of man-made fibre fabrics. $Method for statistical quality control during production: Part I Control charts for
variables ( jirst revision ). @Iethod for statistical quality control during production: Part II Control charts for
