IS 5868 : Part 2 : 2025/ISO 2418 : 2023 Leather - Methods of Sampling - Part 2 Position and Preparation of Specimens for Testing for Chemical, Physical, Mechanical and Fastness Tests
NATIONAL FOREWORD
This Indian Standard which is identical to ISO 2418 : 2023 'Leather - Chemical, physical, mechanical and fastness tests - Position and preparation of specimens for testing' 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 1969 under the title 'Method of sampling of leather' and prescribed the methods of sampling for non-fabricated leather in the form of whole hides of skins, sides, butts, bends, bellies or shoulders.
The first revision was undertaken in 1983 by taking assistance from ISO 2418 : 1972, ISO 2419 : 1972, ISO 2588 : 1973 and ISO 4044 : 1977. The Committee while revising the standard decided to adopt the latest versions of ISO 2418 : 2023, ISO 2419 : 2024 and ISO 2588 : 2014 and publish the standard in three parts as given below:
a) IS 5868 (Part 1) for number of items for a gross sample which is the adoption of ISO 2588 : 2014;
b) IS 5868 (Part 2) for position and preparation of specimens for testing for Chemical, physical, mechanical and fastness tests which is the adoption of ISO 2418 : 2023; and
c) IS 5868 (Part 3) for sampling preparation and conditioning for physical and mechanical test which is the adoption of ISO 2419 : 2024
This standard specifies the position of laboratory test specimens within a piece of leather and the method of labelling and marking the laboratory test specimens for future identification. In addition, this document specifies the design of press knives for cutting test pieces and the preparation of test pieces.
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.
