12、responding permissible deviations which apply to machines for general purpose use and normal accuracy. NOTEIn addition to terms used in two of the three official ISO languages (English and French), this International Standard gives in the Annex the equivalent terms in German, Spanish, Italian and Sw
13、edish; these have been included at the request of ISO Technical Committee TC39 and are published under the responsibility of the member bodies for Germany, F.R. (DIN), Spain (IRANOR), Italy (UNI) and Sweden (SIS). However, only the terms and definitions given in the official languages can be conside
14、red as ISO terms and definitions. This International Standard 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 the components etc.), nor to its characteristics (speeds, feeds
15、 etc.) which should generally be checked before testing accuracy. This International Standard does not impose any practical test. For turning lathe machines, practical tests should be exceptions and have to be stated in a previous agreement between the producer and the user. 2 Reference ISO/R230, Te
16、st code for machine tools. 3 Preliminary remarks 3.1 In this International Standard all dimensions and permissible deviations are expressed in millimetres. 3.2 To apply this International Standard, reference should be made to ISO/R230, especially for installation of the machine before testing, the w
17、arming up of the main spindle and other moving parts, and description of measuring methods. The measuring instruments shall not permit errors over1/3 of the checked tolerances. 3.3 The sequence in which the geometrical tests are given is related to the sub-assemblies of the machine and this in no wa
18、y defines the practical order of testing. In order to make mounting of instruments or gauging easier, tests may be applied in any order. 3.4 When inspecting a machine, it is not always possible or necessary to carry out all the tests given in this International Standard. 3.5 It is up to the user to
19、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. 3.6 A movement is longitudinal when it takes place in the working direction of the piece. 3.7 When establishing the toler
20、ance for a measuring range different from that given in this International Standard (see2.311 in ISO/R230), it should be taken into consideration that the minimum value of the tolerance is0,01mm.BS4361-21:1989 2 BSI 12-1999 4 NomenclatureBS4361-21:1989 BSI 12-1999 3BS4361-21:1989 4 BSI 12-1999 Refer
