FOREWORD This Indian Standard (Fourth Revision) was adopted bythe Bureau ofIndian Standards, after the draft finalized by the Bicycles Sectional Committee had been approved by the Transport Engineering Division Council. This standard was fust published in 1963 and subsequently revised in 1969, 1985 and 1991. In this revision nylon fabric for tyre cord has also been included. The additional tyre sizes which are prevalent in use by the consumers atpresent havebeen included. While preparing this standard considerable assistance has been drawn from ISO 5775-1:1997 ‘Bicycle tyres and rims — Part 1:Tyre designations and dimensions’. The composition ofthe Committee responsible for the formulation ofthis standard isgiven inAnnex F. For the purpose of deciding whether aparticular requirement ofthis standard iscompliedwith, the final value, observed orcalculated, expressingtheresultofatestoranalysis,shallberounded offinaccordancewithIS2:1960 ‘Rules forrounding off numerical values (revised)’. Thenumber ofsignificant places retained intherounded-off value should be the same asthat ofthe specified value inthis standard.
