IS/ISO/TR 79 : 2015 Reference Materials - Examples of Reference Materials for Qualitative Properties

NATIONAL FOREWORD

This Indian Standard which is identical to ISO/TR 79 : 2015 'Reference materials - Examples of reference materials for qualitative properties' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Reference Materials Sectional Committee and approval of the Management and Systems Division Council.

The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. 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'; 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.
