Textile Materials Made from Polyolefins (Excluding Cordage) Sectional Committee, TXD 23

FOREWORD

This Indian Standard (Third Revision) was adopted by the Bureau of Indian Standards, after the draft finalized by
the Textile Materials Made from Polyolefins (Excluding Cordage) Sectional Committee had been approved by
the Textiles Division Council.

This standard was first published in the year 1981 by amalgamating IS 8069 (Part 1 and Part 2) and subsequently
revised in 1989. This standard has been revised again to incorporate the following major changes:
a) Type of sacks has been redefined for ease of understanding. Sacks have been specified for packing
pesticides in 5 kg and 10 kg small size, 25 kg medium size and 50 kg large size sacks;
b) Fabric construction has been revised considering the developments taken place in raw materials,
processing machinery and in line with present packaging requirements;
c) Requirement for breaking strength of the fabric has been modified;
d) Requirement for bottom seam strength has been modified;
e) Requirement for ash content has been included;
f) Considering the risk involved in the transportation and handling of toxic pesticides, and the health and
safety of labourers handling these sacks, as well as, end consumers, the raw material type has been
modified to UV stabilized HDPE/PP resin;
g) Method of test for UV resistance is added;
h) Marking requirements have been modified to include the environment-friendly recycling logo on the
bags; and
j) Sampling and criteria for conformity have been modified.

The composition of the Committee responsible for the formulation of this standard is given in Annex G.

For the purpose of deciding whether a particular requirement of this standard is complied with, the final values,
observed or calculated, expressing the results of tests, shall be rounded off in accordance with IS 2 : 2022 ‘Rules
for rounding off numerical values (second revision)’. The number of significant places retained in the rounded off
values should be the same as that of the specified values in this standard.
