FOREWORD
This Indian Standard (First Revision) wasadopted bythe Bureau ofIndian Standards, afterthe draft finalized by
the Automotive Body, Chassis, Accessories andGarage Equipment Sectional Committee had been approved by
the Transport Engineering Division Council.
Thisstandardhasbeendevelopedtocovertherequirementsofthesafetytounprotectedroadusers,mainlypedestrians,
cyclists and two wheeler riders to protect them against the risk of falling under the sides of vehicles and being
caught under thewheels.
Inpreparation ofthis standard considerable assistancehasbeen derived from the ECE Regulation 73 ‘Uniform
provisions concerning the approval of goods vehicles trailers, trailers and semi-trailers with regard to their
lateral protection’.
Inthisrevision, clause onGeneral Requirement hasbeen included andScopehasbeen modified.
Thecomposition ofthe Committee responsible forformulation ofthisstandard isgiven inAnnex B.
Forthe purpose of deciding whether aparticular requirement of this standard iscomplied with, the final value,
observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with
1S2:1960 ‘Rules for rounding off numerical values (revised)’. The number ofsignificant places retained inthe
rounded off value should be the same asthat ofthe specified value inthis standard.
