9、dwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on
10、that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted i
11、n accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Atte
12、ntion is drawn to the possibility that some of the elements of this part of ISO 6743 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 6743-99 was prepared by Technical Committee ISO/TC 28, Petroleum produ

17、l oils and related products, designated by the prefix letter “L”. Within class L, 18 families of products are defined, according to the application areas of each, so as to cover, as much as possible, all the applications where lubricants, industrial oils and related products are used. The detailed c
18、lassification of each family is given in other parts of ISO 6743. The classification only applies to new products. 2 Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of this part of ISO 6743. For dated references, s
19、ubsequent amendments to, or revisions of, this publication do not apply. However, parties to agreements based on this part of ISO 6743 are encouraged to investigate the possibility of applying the most recent edition of the normative document indicated below. For undated references, the latest editi
20、on of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards. ISO 3448:1992, Industrial liquid lubricants ISO viscosity classification 3 Explanation of symbols 3.1 The principle of the detailed classification of a family is ba
21、sed on the definition of a given number of categories of products needed for the main applications in which the said family is used. Table 1 gives the list of the 18 families defined for class L. 3.2 Each category is designated by a group of letters, which together constitute a code. NOTE The first
22、letter of this code identifies the family of the product considered, but the following letters, taken separately, have no significant meaning. BSISO674399:20021ISO -3476:99)E(2002 2 ISO 2002 Ar llithgr seresvde The designation of each product can be completed, for example, by the addition of the vis
23、cosity class in accordance with ISO 3448 for liquid lubricants or to the NLGI 1)class of penetration for the greases. 3.3 In the present system of classification, the designation of the products is carried out in a uniform way. For example, a particular product can be designated under its complete f
24、orm, i.e. ISO-L-AN 32, or under its abbreviated form, i.e. L-AN 32, the number designating, in accordance with ISO 3448, the viscosity class. 1) NLGI: National Lubricating Grease Institute (USA). This Institute has classified the greases according to their consistency measured in the conditions defi
25、ned by the depth of penetration of a normalized cone (this method of determination of the penetration is dealt with in ISO 2137). This classification is as follows: NLGI class Penetration on greases worked 60 strokes 000 445 to 475 00 400 to 430 0 355 to 385 1 310 to 340 2 265 to 295 3 220 to 250 4
