This standard was originally published in 2003 and subsequently revised in 2013. This second revision has been undertaken to harmonize it with ISO 6103 : 2014. In this revision, besides other changes, includes:

b) types of bonded abrasive products for hand-held grinding machines in Table 1 have been amended; and

c) diameter ranges in Table 1 have been corrected.

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’.

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.
