IS 14321 : 2024/ISO 9224 : 2012 Corrosion of Metals and Alloys - Corrosivity of Atmospheres - Guiding Values for The Corrosivity Categories
NATIONAL FOREWORD
This Indian Standard (First Revision) is identical to ISO 9224 : 2012 ‘Corrosion of metals and alloys - Corrosivity of atmospheres - Guiding values for the corrosivity categories’ 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 1995. This revision has been undertaken to align with the International Standard ISO 9224 : 2012 under dual numbering system.
Former title of the Indian Standard IS 14321 was 'Corrosion of metals and alloys - Recommended values for the corrosivity categories of atmospheres' which is changed to 'Corrosion of metals and alloys - Corrosivity of atmospheres - Guiding values for the corrosivity categories' as per the title of ISO 9224.
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'; and
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.
