fOJ<EWORD
This Indian Standard (First Revision) was adopted by the Bureau of Indian Standards, after the draft
final izcd by the Textile Materials Made from Polyolefins (Excluding Cordage) Sectional Committee had
been approved by the Textile Division Council.
This Standard is based on provisional specification No. S/6004/TC-5 ‘Specification for NIV HDPE sand
sacks, Khaki’ issued by Control lerate of Quality Assurance Textiles and Clothing, Ministry of Defence,
Government of India, Kanpur.
These sacks when filled with sand are used for constructing wall’s for temporary shelters, protection against
firing in the battle field and also as barricades against floods.
This standard, first published in 1995, has been revised to incorporate the following changes:
a) To include the polypropylene sack.
b) To increase the breaking strength of warp, weft and seam.
c) To incorporate ultra-violet resistance test.
d) To modify the sampling and criteria for conformity.
The composition of the Committee responsible for formulation of this standard is given in Annex D.
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 1S 2 : 1960 ‘Rules for rounding off numerical values (revised)’. The number of significant places retained
i()the rounded off value should be the same as that of the specified value in this standard.
