IS 582 : Part 8 : Sec 1 : 2024/ISO 13365-1 : 2020 Methods of Chemical Testing of Leather - Part 8 Determination of the Preservative (TCMTB, PCMC, OPP, OIT) Content in Leather by Liquid Chromatography - Section 1 Acetonitrile Extraction Method
NATIONAL FOREWORD
This Indian Standard (Part 8/Sec 1) which is identical to ISO 13365-1 : 2020 'Leather Chemical determination of the preservative (TCMTB, PCMC, OPP, OIT) content in leather by liquid chromatography - Part 1: Acetonitrile extraction method' 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.
IS 582 : 1970 'Methods of chemical testing of leather (first revision)' prescribes the methods of chemical testing for all types of leather. The Committee responsible for formulating this standard had decided to harmonize the methods of test prescribed in IS 582 with those prescribed in ISO/IULTCS standards. Accordingly, the committee decided to retain IS 582 and publish the harmonized/adopted test methods published by ISO/IULTCS in various parts of IS 582 as this standard is widely recognized by the Indian leather industry.
The committee had further decided to publish the adopted/harmonized standards in the following manner:
a) Wherever an existing test method is being replaced by the corresponding ISO/IULTCS test method, the relevant part will be published with the information in the national foreword about the method of IS 582 being superseded; and
b) When a new test method is being incorporated in IS 582, the same will be published as a new standard and as a subsequent part/section of IS 582.
