[ Superseding IS 16296 (Part 3) : 2014 ]

New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 10/Sec 3) which is identical with ISO 5398-3 : 2018 ‘Leather - Chemical determination of chromic oxide content - Part 3: Quantification by atomic absorption spectrometry’ issued by the International Organization for Standardization (ISO), was adopted by the Bureau of Indian Standards on recommendation of the Leather, Tanning Materials and Allied Products Sectional Committee and approval of the Chemical Division Council.

The Indian Standard IS 16296 (Part 3) : 2014 is the identical adoption of ISO 5398-3 : 2007 ‘Leather - Chemical determination of chromic oxide content - Part 3: Quantification by atomic absorption spectrometry’ while the Indian Standard IS 582 : 1970 ‘Methods of chemical testing of leather (first revision)’ prescribes the methods of chemical testing for all types of leathers and includes determination of chromic oxide in LC:10. Hence, there are two standards on the same subject.
