STEEL PLATE FOR PRESSURE VESSEL FOR
INTERMEDIATE AND HIGH TEMPERATURE SERVICE
INCLUDING BOILERS
( Third Revision
@ BIS 2009
FOREWORD
This Indian Standard (Third Revision) was adopted by the Bureau of Indian Standards, after the”draft finalized
by the Wrought Steel Products Sectional Committee had been approved by the Metallurgical Engineering Division
Council.
This standard was first published in 1962 and subsequently revised in 1982 and 1992. While reviewing this
standard, in the light of experience gained during these years, the Committee decided to revise it to bring.in line
with the present practices being followed by the Indian industry and ovmeas statidards of hot rolled steel plates
for pressure vessels including boilers. .
a) Clauses on scope, terminology, manufacture, heat treatment, tolerances, tensil,e test and re-tests have
. been modified;
b) Definitions of Normalizing and Normalizing Rolling have been added;
c) Amendment Nos. 1, 2, 3 and 4 have been incorporated;
d) A new clause on references has been incorporated;
e) Requirements of tolerances on dimensions and shape has been added and adopted 1S0 7452:2002
‘Hot-rolled structural steel plates — Tolerances on dimensions and shape’; and
f) Figure for position of test strips in rolled plates has been deleted.
For the tests specified in this standard (chemical/ physical/ others), the method as specified in the relevant 1S0
Standard may also be followed as an alternate method.
The composition of the Committee responsible for formulation of this standard is given in Annex A.
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
‘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.

Permissible upper deviation from the theoretical mass shall comply to Table 2.
Whereas, the permissible lower deviation shall be calculated based on the
