IS 6919 : 2020/ISO 1136 : 2015 Wool - Determination of Mean Diameter of Fibres - Air Permeability Method
Reaffirmed 2024
NATIONAL FOREWORD
This Indian Standard (First Revision) which is identical with ISO 1136 : 2015 ‘Wool — Determination of mean diameter of fibres — Air permeability method’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Physical Methods of Test Sectional Committee and approval of the Textile Division Council.
This standard was originally published in 1973. The first revision of this standard has been undertaken to align it with the latest version of ISO 1136 : 2015 .
The text of ISO Standards has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies 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’.
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.
