NATIONAL FOREWORD

This Indian Standard (Part 1) (Second Revision) which is identical with ISO 6753-1 : 2005 ‘Tools for pressing and moulding - Machined plates - Part 1: Machined plates for press tools’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Metal Forming Machines Sectional Committee and approval of the Production and General Engineering Division Council.

This standard was first published in 1985 under dual numbering identical with ISO 6753 : 1982. Subsequent to revision of the ISO Standard in two parts, the Indian Standard was also revised in two parts in 2003. With the revision of ISO Standard again, this standard is revised to keep pace with the technological developments. The other part in this series is:

Part 2 Machined plates for moulds

The text of the ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain 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.

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 the rounded off value should be the same as that of the specified value in this standard.
