NATIONAL FOREWORD

This Indian Standard (Part 15) which is identical with ISO 9073-15 : 2007 ‘Textiles - Test methods for nonwovens - Part 15: Determination of air permeability’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Industrial Fabrics Sectional Committee and approval of the Textile Division Council.

This standard has been published in various parts. The other parts in this series are:

Part 1 Determination of mass per unit area

Part 2 Determination of thickness

Part 3 Determination of tensile strength and elongation

Part 4 Determination of tear resistance

Part 5 Determination of resistance to mechanical penetration (ball burst procedure)

Part 6 Absorption

Part 7 Determination of bending length

Part 8 Determination of liquid strike-through time (simulated urine)

Part 9 Determination of drapability including drape coefficient

Part 10 Lint and other particle generation in the dry state

Part 11 Run-off

Part 12 Demand absorbency

Part 13 Repeated liquid strike-through time

Part 14 Coverstock wetback

Part 16 Determination of resistance to penetration by water (hydrostatic pressure)

Part 17 Determination of water penetration (spray impact)

Part 18 Determination of breaking strength and elongation of nonwoven materials using the grab tensile test

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.
