FOREWORD

This Indian Standard (Third Revision) was adopted by Bureau of Indian Standards, after the drafl finalized bythe Bicycles Sectional Committee had been approved by the Transport Engineering Division Council.

This Standard was first published in 1958 and subsequently revised in 1968 and 1985. ‘PH’ type and ‘R’ typebicycle bottom bracket lock rings were covered in two separate standards, namely, IS 1134 : 1985 andIS 11736: 1986. This revision of the standard is being taken up to:

a) include ‘Holes’ type bicycle bottom bracket lock rings, and

b) amalgamate IS 1134: 1985 with IS 11736: 1986 since most of the requirements of both types of lockrings are same.

The composition of the Committee responsible for the 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 withIS 2:1960 ‘Rules for rounding off numerical values (revised)’, The number of significant places retained in therounded off value should be the same as that of the specified value in this standard.
