NATIONAL FOREWORD
This Indian Standard (Part 2) (First Revision) which is identical with ISO 12958-2 : 2020 'Geotextiles and geotextile-related products - Determination of water flow capacity in their plane - Part 2 : Performance test' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Geosynthetics Sectional Committee and approval of the Textiles Division Council.
The standard was first published in 2019. The first revision of the standard has been undertaken to align it with the latest version of ISO 12958-2.
Since, ISO 12958 has been published in two parts, in this revision this standard has also been bifurcated in two parts. Other part is as under:
Part 1 Index test
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.
