IS 14575 : 2024/ISO 17070 : 2015 Leather - Chemical Tests - Determination of Tetrachlorophenol - ,Trichlorophenol-, Dichlorophenol-, Monochlorophenol- Isomers and Pentachlorophenol Content
NATIONAL FOREWORD
This Indian Standard (First Revision) which is identical to ISO 17070 : 2015 'Leather - Chemical tests - Determination of tetrachlorophenol-, trichlorophenol-, dichlorophenol-, monochlorophenolisomers and pentachlorophenol content' issued by the International Organization for Standardization (ISO), was adopted by the Bureau of Indian Standards on the recommendation of the Leather, Tanning Materials and Allied Products Sectional Committee and approval of the Chemical Division Council.
This standard was first published in 1999. The Committee responsible for formulating this standard has decided to revise the standard and harmonize the standard with latest ISO standard ISO 17070 : 2015. This standard specifies a method for determining the content of tetrachlorophenol-, trichlorophenol-, dichlorophenol-, monochlorophenol-isomers, and pentachlorophenol, its salts, and esters in leather.
The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions and terminologies 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 in the International Standard, while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
