IS 12125 : 2024/ISO 3618 : 1994 Benzotriazole, Photographic Grade - Specification
NATIONAL FOREWORD
This Indian Standard (First Revision), which is identical to ISO 3618 : 1994 'Photography - Processing chemicals - Specifications for benzotriazole' issued by the International Organization for Standardization (ISO), was adopted by the Bureau of Indian Standards on the recommendation of the Electroplating Chemicals and Photographic Materials Sectional Committee and approval of the Chemical Division Council.
Benzotriazole is used as a photographic antifogging agent in processing. It is also known as 1, 2, 3-benzotriazole, 1-H-benzotriazole and benzisotriazole.
This standard was first published in 1987. Now this standard has been revised by adopting ISO 3618 : 1994 Photography - Processing Chemicals - Specification for Benzotriazole on dual number basis.
The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appears referring to this standard, they 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.
