The work of preparing International Standards is no
11、rmally 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 that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in
12、 the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepa
13、re International Standards. 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. Attention is drawn to the possibility that so
14、me of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 19378 was prepared by Technical Committee ISO/TC 28, Petroleum products and lubricants, Subcommittee SC 4, Classifications and specifications.

This International Standard does not purport to address all of the safety problems associated with its use. It is the responsibility o
17、f the users of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1 Scope This International Standard provides the manufacturers and users of machine tools with criteria for the choice among the various categorie
18、s of lubricants and gives specifications for these lubricants. This International Standard facilitates the application of ISO 5169 relating to the presentation of lubrication instructions for machine tools. 2 Normative references The following referenced documents are indispensable for the applicati

32、oducts defined and described in ISO 6743-1, ISO 6743-2, ISO 6743-4, ISO 6743-6, ISO 6743-9, ISO 6743-13 and ISO 6743-99. Each part of ISO 6743 defines categories inside a lubricant family. Within each category, all the grades defined in accordance with ISO 3448 for liquid lubricants or ISO 6743-9 fo
33、r greases are possible. For the lubrication of machine tools, all the categories of products and all the possible grades in each category are not useful. Therefore, to facilitate the selection by the manufacturers or the users of machine tools, it is advisable to limit the number of categories and g
34、rades of products. Table 1 gives criteria for the applications and defines a limited range of products appearing underlined. It is recommended to the manufacturers of machine tools, whenever possible, to select the lubricants in the limited range. Table 1 does not cover special applications requirin
35、g the use of specific lubricants. These special applications should be examined separately, case by case, by the manufacturers or users of machine tools. 5 Specifications of products The products of Family H, classified in ISO 6743-4, are specified in ISO 11158 and the products of Family C, classifi
36、ed in ISO 6743-6, are specified in ISO 12925-1. There is presently no specification covering the products of Family X, classified in ISO 6743-9. NOTE At the time of publication of this International Standard, an International Standard for specifications of greases is in the course of development at
37、the preliminary stage (see Annex A). Table 2 gives the requirements of the categories of lubricants L-AN (ISO 6743-1), L-FC and L-FD (ISO 6743-2) and L-G (ISO 6743-13) covered by Table 1. The properties are those applying to the products at the time of their delivery. The application of the accuracy
38、 in interpreting the results of tests is described in ISO 4259. This procedure shall be applied in case of dispute. 6 Packaging and labelling 6.1 Packaging The lubricants shall be packed in suitable packaging and according to the regulations in use. 6.2 Labelling The labelling shall comprise at leas
39、t the following information: a) the commercial name of the product; b) the ISO designation code (including the viscosity grade); c) the batch number; d) the date of manufacturing; e) the legal labelling (transportation, safety) if the product is liable for this labelling.
