Disclosure to Promote the Right To Information

Whereas the Parliament of India has set out to provide a practical regime of right to
information for citizens to secure access to information under the control of public authorities,
in order to promote transparency and accountability in the working of every public authority,
and whereas the attached publication of the Bureau of Indian Standards is of particular interest
to the public, particularly disadvantaged communities and those engaged in the pursuit of
education and knowledge, the attached public safety standard is made available to promote the
timely dissemination of this information in an accurate manner to the public.

FOREWORD
This Indian Standard (First Revision) was adopted by the Bureau of Indian Standard, after the draft finalized by
Chemical Methods of Test Sectional Committee had been approved by Textile Division Council.
This Indian Standard was first published in 1967 and has been revised to accommodate use of benzyl alcohol as
solvent for waluating solvent soluble matter in cotton textiles presently covered in IS 5152 : 1969. As a result
of above 1S 5152 : 1969 stands withdrawn.
There is no International standard on the subject,
The composition of the Committee responsible for formulation of this standard is given in Annex A.
In reporting the result of a test made in accordance with this standard, if the final value, observed or calculated,
is to be rounded off, it shall be done in accordance with IS 2: 1960 ‘Rules for rounding off numerical values
(revised)’.

Review of Indian Standards

Amendments are issued to standards as the need arises on the basis of comments. Standards are also reviewed
periodically; a standard along with amendments is reaffirmed when such review indicates that no changes are
needed; if the review indicates that changes are needed, it is taken up for revision. Users of Indian Standards
