Indian Standard LIVE WORKING—TERMINOLOGY FOR TOOLS, EQUIPMENT AND DEVICES ICS 01040:29:29.260.99 @BIS 2003 BUREAU OF INDIAN STANDARDS MANAK BHAVAN, 9 BAHADUR SHAH ZAFAR MARG NEW DELHI 110002 December 2003 Price Group 17 Tools and Equipment for Live Working Sectional Committee, ET 36 NATIONAL FOREWORD This Indian Standard which is identical with IEC 60743 (2001) ‘Live working —Terminology for tools, equipment and devices’ issued by the International Electrotechnical Commission (lEC) was adopted by the Bureau of Indian Standards on the recommendations of the Tools and Equipment for Live Working Sectional Committee (ET 36) and approval of the Electrotechnical Division Council. The text of the IEC Standard has been approved as suitable for publication as an Indian Standard without deviation. Inthe adopted standard, certain terminology and conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following: a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’. b) Comma (,) has been used as a decimal marker, while in Indian Standards, the current practice is to use a point (.) as the decimal marker. CROSS REFERENCE In this adopted standard, reference appears to the following International Standard for which Indian Standard also exists. The corresponding Indian Standard which is to be substituted in its place is fisted below along with its degree of equivalence for the edition indicated: International Standard -Corresponding Indian Standard Degree of Equivalence ISO 472 : 1999 Plastics— IS 2828:2001 Plastics—Vocabulary (first Identical Vocabulary revision) The Technical Committee respo nsible for the-preparation of this standard has reviewed the provisions of the following International Standar ds referred to in this adopted standard and has decided that they are acceptable for use in conjunction with this standard.
