Each member body interested in a subject for which a technical committee has been established has the right to be re
5、presented on that committee. International organizations, govern- mental and non-governmental, in liaison with ISO, also take part in the work. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International
6、Standards by the IS0 Council. They are approved in accordance with IS0 procedures requiring at least 75 % approval by the member bodies voting. International Standard IS0 6743/7 was prepared by Technical Committee ISO/TC 28, Petroleum products and lubricants. Users should note that all International

12、anation of symbols used 3.1 This detailed classification of family M has been established by defining the categories of products required for the main applications of this family. 3.2 Each category is designated by a symbol consisting of a group of three letters, which together constitute a code. NO
13、TE - The first letter of the category (M) identifies the family of the product considered but any following letters taken separately have no significance on their own. The designation of each category can be supplemented by the addition of viscosity grades according to IS0 3448. 3.3 In this classifi
14、cation system, products are designated in a uniform manner. For example, a particular product may be designated in the complete form, i.e : ISO-L-MHA 32, or in an abbreviated form, i.e. : L-MHA 32, the number indicating the class of viscosity according to IS0 3448. 4 Classification of lubricants for
