NATIONAL FOREWORD
This Indian Standard which is a modified adoption of ISO 6521-1 : 2019 ‘Lubricants, industrial oils and related products (Class L) Family D (compressors) - Part 1: Specifications of categories DAA and DAB (lubricants for reciprocating and drip feed rotary air compressors)’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Lubricants and their Related Products Sectional Committee and approval of the Petroleum, Coal and Related Products Division Council.
This standard supersedes IS 13256 : 1992 ‘Air compressor lubricants - Types DAA and DAB - Specification’. In this standard, technical deviations have been made to incorporate food grade requirement for lubricants. These technical deviations are identified in National Annex A. Except the deviations identified in National Annex A, the text of the ISO standard has been approved as suitable for publication as an Indian Standard. 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’ appear 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.
