IS 8602 : 2024/ISO 3613 : 2021 Metallic and Other Inorganic Coatings - Chromate Conversion Coatings on Zinc, Cadmium, Aluminium-Zinc Alloys and Zinc-Aluminium Alloys - Methods of Test
NATIONAL FOREWORD
This Indian Standard (First Revision) is identical to ISO 3613 : 2021 'Metallic and other inorganic coatings - Chromate conversion coatings on zinc, cadmium, aluminium-zinc alloys and zinc-aluminium alloys - Test Methods' issued by the International Organization for Standardization (ISO), was adopted by the Bureau of Indian Standards on the recommendation of Corrosion Protection and Finishes Sectional Committee and approval of the Metallurgical Engineering Division Council.
This standard was first published in 1977 with title 'Methods of tests for chromate conversion coatings on zinc and cadmium surfaces'. The first revision of this standard was brought out to align with the latest International Standard ISO 3613 : 2021 under dual numbering system.
The text of ISO standard has been approved as suitable for publication as in Indian Standard without deviations. Certain terminologies and conventions are, however, not identical with those used in Indian Standard. Attention is especially drawn to the following:
a) Wherever the words 'International Standard' appear referring to this standard, it should be read as 'Indian Standard';
b) Comma (,) has been used as a decimal marker while in Indian Standards the current practice is to use a point (.) as the decimal marker.
