FOREWORD
This Indian Standard was adopted by the.Bureauof Indian Standards, after the draft finalized by the Wrought
Steel Products Sectional Committee hadbeen approved bythe Metallurgical Engineering Division Council.
InIndia, certain small scalere-rolling millsareproducing hotrelied narrow width steelstrips,popularly known as
Patra. Keeping the interest ofthesesteelmills inview,aneedwasfelttoformulate anIndian Standard tofacilitate
manufacture ofquality hot rolled steelnarrow width strip which willbeused formanufacturing ofwelded tubes
and pipes for non-critical applications.
For all the tests specified in this standard (chemical/physicaUothers), the method as specified in relevant 1S0
Standard may alsobe followed asanalternate method.
The composition ofthe Committee responsible forthe formulation ofthis standard isgiven inAnnex A.
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 with
IS2:1960 ‘Rules forrounding off numerical values (revised)’. Thenumber ofsignificant places retained inthe
rounded off value should bethe same asthat ofthe specified value inthis standard.
