IS 15290 : 2024/ISO 9138 : 2015 Abrasive Grains - Sampling and Splitting
NATIONAL FOREWORD
This Indian Standard (First Revision) which is identical to ISO 9138 : 2015 'Abrasive grains - Sampling and splitting' issued by the International Organization for Standardization (ISO), was adopted by the Bureau of Indian Standards on recommendation of the Abrasives Sectional Committee and approval of the Production and General Engineering Division Council.
This standard was first published in 2003. This revision of this standard has been undertaken to align it with latest version of ISO 9138.
The major changes have been incorporated in this revision are as follows:
a) Many more detailed specifications are included in the entire document;
b) Requirements for four different types of sampling are specified;
c) A detailed description of the splitter is included;
d) Whole sampling and splitting procedure described in much more detail for big-bags and paper- bags; and
e) A detailed specification of sampling preparation included.
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.
