4、stitutes (IS0 member bodies). The work of developing Inter- national Standards is carried out through IS0 technical committees. Every member body interested in a subject for which a technical committee has been set up has the right to be represented on that committee. International organizations, go
5、vernmental and non-governmental, in liaison with ISO, also take part in the work. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the IS0 Council. International Standard IS0 6779
6、was developed by Technical Committee ISO/TC 39, Machine too/s, and was circulated to the member bodies in October 1979. It has been approved by the member bodies of the following countries : Australia Japan Belgium Korea, Rep. of Germany, F. R. Poland Hungary Romania India South Africa, Rep. of Ital

9、nal type - Testing of accuracy 1 Scope and field of application This International Standard specifies, with reference to ISO/R 230, both preliminary levelling operations and geometri- cal tests on general purpose and normal accuracy machines, and gives the corresponding permissible deviations which
10、apply. This International Standard also gives the terminology used for the main elements of the machine. 1 It deals only with the verification of accuracy of the machine. It does not apply to the testing of the running of the machine (vibrations, abnormal noises, stick-slip motion of components, etc
11、.), or to its characteristics (speeds, feeds, etc.) which should generally be checked before testing accuracy. 2 Reference ISO/R 230, Machine tool test code. 3 Preliminary remarks 3.1 In this International Standard, all the dimensions and per- missible deviations are expressed in millimetres and in
12、inches. 3.2 To apply this International Standard, reference should be made to ISO/R 230, especially for installation of the machine before acceptance, warming up of moving parts, description of measuring methods, and recommended accuracy of testing equipment. 3.3 The sequence in which the geometrica
13、l tests are given is related to the sub-assemblies of the machine and this in no way defines the practical order of testing. In order to make the mounting of instruments or gauging easier, tests may be ap- plied in any order. 3.4 When inspecting a machine, it is not always necessary to carry out all
14、 the tests given in this International Standard. It is up to the user to choose, in agreement with the manufacturer, those tests relating to the properties which are of interest to him, but these tests are to be clearly stated when ordering a machine. 3.5 Because of the diversity of shape of the pie
15、ces, the prac- tical tests have not been given. If the user wishes to carry out a practical test, this one has to be stated in agreement with the manufacturer. 3.6 When establishing the tolerance for a measuring range different from that given in this International Standard (see clause 2.311 in ISO/
