NATIONAL FOREWORD

This Indian Standard (Second Revision) was adopted by the Bureau of Indian Standards, after the draft finalized by the Ceramicware Sectional Committee and approved by the Chemical Division Council.

This standard was first published in 1987 as 'Permissible limits and test methods for toxic materials released from enamelware in contact with food'. During the first revision, the Committee felt that it will be more convenient to split the standard into two parts by adoption of ISO 4531-1 : 1998 andISO 4531-2 : 1998, where Part 1 covers method of test and Part 2 covered permissible limits.

ISO 4531-1 : 1998 and ISO 4531-2 : 1998 were combined and technically revised by publication of ISO 4531 : 2018. Further, ISO 4531 : 2018 has been revised by ISO 4531 : 2022.

Accordingly, this revision has been taken up in order to align the standard with latest version of ISO 4531 : 2022 by amalgamating IS 12038 (Part 1) : 2007 and IS 12038 (Part 2) : 2007 and published as IS 12038.

This standard specifies a simulating method of test for determination of the release of metal-ions from enamelled articles, which are intended to come into contact with food. It also specifies limits for the release of metal-ions from enamelled articles, which are intended to come into contact with food.

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 beread as 'Indian Standard'; and

b)Comma (,) has been used as a decimal marker in the International Standard, while inIndian Standards, the current practice is to use a point (.) as the decimal marker.
