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.

0. FOREWORD
0.1 This Indian Standard was adopted by the Indian Standards
Institution on 12 April 1966 as an emergency standard. After the
original standard had been reviewed by the Paints and Allied Products
Sectional Committee and approved by the Chemical Division Council,
the emergency character of this standard was removed through
Amendment No. 1.
0.2 This standard was originally issued as IS : 3537E-1966 in accordance
with the simplified emergency procedures to meet the urgent needs of
the country. It was issued as an alternative to the following standards:
IS : 129-1950 Specification for ready mixed paint, brushing, finish-
ing, interior, oil gloss, for general purposes, to Indian Standard
colours

1
IS : 3537 - 1966

IS : 133-1965 Specification for enamel, interior (a) undercoating,

(b) finishing, colour as required ( revised )
IS : 641-1964 Specification for ready mixed paint, brushing, finish-
ing, interior, semi-gloss, for general purposes, white (revised)
IS : 870-1962 Specification for ready mixed paint, brushing, finish-
ing, egg shell gloss, for interior use, to Indian Standard
colours
IS : 871-1956 Specification for ready mixed paint, brushing, finish-
ing, egg shell gloss, for interior use, to Indian Standard
colours
It was prepared with the assistance of an ad hoc Consultative Group
composed of representatives of Ministry of Defence; Directorate
General of Supplies and Disposals; Ministry of Railways; Indian Paint
Association; and other manufacturers, technologists and testing
authorities under the convenership of Shri K. N. R. Sharma, Develop-
ment Officer (Paints), Directorate General of Technical Development,
New Delhi.
0.2.1 This standard is expected to help not only in easing the
stringent foreign exchange position by replacing imported raw
materials with alternative indigenous products but would also econo-
mize the use of indigenous raw materials, such as drying oils, which
may thus be released for export. In this standard, use of lead and zinc
pigments has been eliminated. An amended list of colours now possible
under this specification has been given. Restriction in the range of
choice of colours to 26 shades, for internal consumption only, has been
attempted in order to promote conservation of raw materials, optimi-
zation of production and necessary import substitution through
rationalization of the requirements of the consumer. As material to
this specification may be produced in different types of finish (gloss,
semi-gloss, egg shell and matt) while indenting, type of finish required
shall be specifically stated.

0.3 This standard contains clause 3.5 which calls for an agreement
between the purchaser and the supplier.
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 : 2-1960*. The number of significant places retain-
ed in the rounded off value should be the same as that of the specified
value in this standard.
*Rules for rounding off numerical values ( revised ).

conveys the assurance that they have been produced to comply with the requirments
of that standard under a well-defined system of inspection, testing and quality
control which is devised and supervised by ISI and operated by the producer. ISI
marked products are also continuously checked by ISI for conformity to that standard
as a further safeguard. Details of conditions under which a licence for the use of
the ISI Certification Mark may be granted to manufacturers or processors, may be
obtained front the Indian Standards Institution.
