4、e from IHS -,-,- Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards institutes (IS0 member bodies). The work of developing Inter- national Standards is carried out through IS0 technical committees. Every member body interested in a subje
5、ct for which a technical committee has been set up has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. Draft International Standards adopted by the technical committees are circulated to t
6、he member bodies for approval before their acceptance as International Standards by the IS0 Council. International Standard IS0 6743/Z was developed by Technical Committee ISO/TC 28, Petroleum products and lubricants, and was circulated to the member bodies in August 1980. It has been approved by th

10、gs 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 the class L (Lubricants, industrial oils and related products). It should be read in conjunctio
11、n 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 defining the categories of products required for the main applications of this family and at t
12、he 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 - The first letter of the code (F) identifies the family of the product considered but the seco
13、nd 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, products are designated in a uniform manner. For example, a particular product may be designat
14、ed 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.
