8、 and related products (class L) - Classification - Part 2 : Family F (Spindle bearings, bearings and associated clutches) 1 Scope and field of application This part of IS0 6743 establishes the detailed classification of family F (Spindle bearings, bearings and associated clutches) which belongs to t

9、he class L (Lubricants, industrial oils and related products). It should be read in conjunction with IS0 6743/O. 2 Reference I SO 3448, Industrial liquid lubricants - IS0 viscosity classifica- tion. 3 Explanation of symbols used 3.1 This detailed classification of family F has been estab- lished by

10、defining the categories of products required for the main applications of this family and at the final point for sub- division by referring to composition of corresponding products. 3.2 Each category is designated by a symbol consisting of a group of letters, which together constitute a code. NOTE -

11、 The first letter of the code (F) identifies the family of the product considered but the second letter taken separately has no significance of its own. The designation of each category can be supplemented by the addition of viscosity grades according to IS0 3448. 3.3 In this classification system,

12、products are designated in a uniform manner. For example, a particular product may be designated in complete form, i.e. ISO-L-FD 68, or in an ab- breviated form, i.e. L-FD 68, the number indicating the viscos- ity grade according to IS0 3448.
