FOREWORD

This Indian Standard ( First Revision ) was adopted by the Bureau of Indian Standards, after the draft finalized by the Sports Goods Sectional Committee had been approved by the Petroleum, Coal and Related Products Division Council.

This standard was first published in 1968. This revision is brought out mainly to align the standard with the latest rules of the International Amateur Athletic Federation, as desired by the Consultative Committee of Parliament for the Department of Youth Affairs and Sports. The alterations mad-e in this revision include modifications in the requirements for materials, mass and construction of the javelins.

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 with IS 2 : 1960 ‘ Rules for rounding off numerical values ( revised ) ‘. The number of significant places retained in t3e rounded off value should be the same as that of the specified value in this standard.
