33、Each category is designated by a symbol consisting of a group of letters which, together, constitute a code.The first letter of the code (H) identifies the family of the product considered but any following letters taken separately have no significance of their own.NOTE The designation of each categ

34、ory can be supplemented by the addition of viscosity grades according to ISO 3448.3.3 In this classification system, products are designated in a uniform manner. For example, a particular product may be designated in complete form, i.e. ISO-L-HV 32, or in an abbreviated form, i.e. L-HV 32, the numbe
