Light Metals and Their Alloys Sectional Committee MTD 7

FOREWORDThis Indian Standard (Third Revision) was adopted by the Bureau of Indian Standards after the draft finalizedby the Light Metals and Their Alloys Sectional Committee had been approved by the Metallurgical EngineeringDivision Council

This standard was first published in 1956 and subsequently revised in 1968 and 1975 While reviewing thisstandard in the light of experience gained during these years the Sectional Committee decided to revise thestandard

In this revision the following modifications have been made

a) Extruded round tubes have been fiu-therdivided into extruded structural tubes and extruded seamless

tubesb) One new aluminium alloy 31000 which is having application for general engineering purposes have

been includedc) Temper condition lsquoOrsquo has been incorporated for Aluminium grade 19000 19500 and Aluminium

alloys 24345 52000 53000 and 54300

The characteristics and typical uses of alloys are given is Annex A

The comparison of new IS tempers with old tempers is given in Annex B

The composition of the Committee responsible for formulation of this standard is given in Annex C

For the purpose of deciding whether 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 withIS 21960 lsquoRules for rounding off numerical values (revisecf)rsquo The number of significant places retained in therounded off value should be the same as that of the specified value in this standard
