3、a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represent
4、ed on that committee. International organizations, governmental and non- governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards
5、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. International Standard IS0 6392-2 was prepared by Technical Committee ISO/TC 127, Earth-moving machiner
6、y, Subcommittee SC 3, Operation and maintenance. This first ,edition of IS0 6392-2 together with IS0 6392-l cancels and replaces IS0 6392:1980, which has been technically revised. IS0 6392 consists of the following parts, under the general title Earth- moving machinery - Lubrication fittings: - Part

10、92 specifies grease-gun nozzles to be used for the injection of grease into the lubrication points of earth-moving machinery by means of the grease fitting specified in part 1 of this International Standard. The grease-gun nozzles covered by this part of IS0 6392 are used on the types of earth-movin
11、g machinery defined in IS0 6165. 2 Normative reference The following standard contains provisions which, through reference in this text, constitute provisions of this part of IS0 6392. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to
12、agreements based on this part of IS0 6392 are encouraged to investigate the possibility of applying the most recent edition of the standard indicated below. Members of IEC and IS0 maintain registers of currently valid International Standards. IS0 6165:-l), Earth-moving machinery - Basic types - Voca
13、bulary. 3 Nozzle type and mounting position 3.1 Nozzle type Nozzle types are divided into two types: the rubber nozzle-centre type (see figure 2) and the steel nozzle-centre type (see figure 3). The rubber nozzle-centre type is recommended for the grease-gun nozzles to be used on earth-moving machin
14、ery. For the grease injection into the grease fitting, the rubber nozzle-centre type is superior in sealability and grease leakage is less compared to the steel nozzle-centre type. 3.2 Mounting position Figure 1 shows an example of the mounting position of the grease-gun nozzle. The specific type of
15、 grease gun is not prescribed. 1) To be published.

When the grease-gun is used in a track adjust
17、er, the grease injection pressure can exceed 50 MPa; the life of the nozzle (number of leak free applications) may decrease if the grease-gun is removed under the residual pressure. It is therefore recommended to use the grease-gun nozzle with a relief valve. 5 Dimensions, materials and finish 5.1 D
