FOREWORD
‘This Indian Standard (Fifth Revision) was adopted by the Bureau of Indian Standards, after the draf finalized
‘by the Steel Castings Sectional Committee had been approved by the Metallurgical Engineering Division Council
This standard was first published in 1956 and was revised in 1962, 1974, 1982 and 1989, While reviewing the
standard in light ofthe experience gained during these years the:committee has decided that the standard may
be further revised. In this revision various clauses have been aligned with the recent standards on steel castings.
‘Amendments No. 1 and 2 have also been incorporated in this revision.
In the preparation of this standard, assistance has been derived from ISO 3755 : 1991 *Cast carbon steels for
general engineering purposes’.
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 atest or analysis, shall be rounded off in a¢cordaiice with
IS 2: 1960 "Rules for rounding off numerical values (revised)". The number of significant places retained in
the rounded off value should be the same as that of the specified value in this standard Indian Standard

16 HYDRAULIC TEST
16.1 | When so specified by the purchaser in enquiry
and the order, a hydraulic test shall be carried out the
details of the test shall be as agreed to between the
Purchaser and the manufacturer.
16.2 The castings shall not be peened, plugged or
impregnated, to stop leakages. However, unless
otherwise specified at the time of enquiry and orden
rectification and upgradation ofa casting by welding
‘may be carried out in accordance withthe approved
Procedures as laid down in the relevant clause of the
standard.
17 METHOD OF SAMPLING
The method of sampling stel castings forthe purpose
of chemical analysis and mechanical tests including
‘e-test shall be in accordance with IS 6907,
18 MARKING
18.1 Each casting shall be legibly marked with the
following as may be relevant. However, where linkage
and traceability are required the relevant marking shall
be indelible:
) The number or identification mark by which
itis possible to trace the melt and the heat-
{eatment batch from which it was made;
+) The manufacturer's initials or trade-mark; and
©) Other identification marks in accordance with
‘any agreement between the purchaser and the
‘manufacturer,
NOTE—It is recommended
sed
18.2 By agreement between the purchaser and the
‘manufacturer, castings complying with the require
‘ments of this standard may, after inspection, be leg
‘bly and indelibly marked with an acceptance mark
183 BIS Certification Marking
‘The castings may also be marked with the Standard
Mark.
18.3.1 The use of Standard Mark is governed by the
Provisions of Bureau of Indian Standards Act, 1986
and the Rules and Regulations made thereunder: The
