ICS 59.140.20

CHD 17

NATIONAL FOREWORD

This Indian Standard (Part 1) (First Revision) which is identical to ISO 22244 : 2020 'Leather - Raw hides -Guidelines for preservation of hides' 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.

The Indian Standard IS 7656 : 1975 'Code of practice for curing and preservation of cattle hides and goat and sheep skins by wet salting method' standard lays down code of practice for curing and preservation of cattle hides (both cow and buffalo) and goat and sheep skins. This is a very old standard and hence it is not exhaustive. The Committee responsible for formulating this standard has decided to harmonize the code of practice with those prescribed in ISO 22244 : 2020 and ISO 22284 : 2020.

Hence, IS 7656 : 1975 has been revised and bifurcated into two parts:

a) IS 7656 (Part 1) for Raw hides which is the adoption of ISO 22244 : 2020; and

b) IS 7656 (Part 2) for Goat and sheep skins which is the adoption of ISO 22284 : 2020.

This standard provides various preservation methods for raw hides. These preservation methods are intended to suppress microbiological activity and to maintain the quality and commercial value of the hides during storage

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 `document' 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.
