IS 2428 : 2024/ISO 513 : 2012 Classification and Application of Hard Cutting Materials for Metal Removal with Defined Cutting Edges - Designation of the Main Groups and Groups of Application
NATIONAL FOREWORD
This Indian Standard (Third Revision) which is identical to ISO 513 : 2012 'Classification and application of hard cutting materials for metal removal with defined cutting edges - Designation of the main groups and groups of application' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Cutting Tools Sectional Committee and approval of the Production and General Engineering Division Council.
This standard was first published in 1975 and subsequently revised in 1999 and 2007. First revision of this standard was identical to ISO 513 : 1991. Second revision of this standard was identical to ISO 513 : 2004. This revision has been brought out to align it with latest version of ISO 513.
The major changes have been incorporated in this revision are as follows:
a) Table 3 has been revised by providing separate identification letters for polycrystalline diamond, with and without binder; and
b) Table 6 'Area of use chart' has been added.
The text of 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'; and
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.
