The work of preparing International Standards is normally carried out through
4、IS0 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, govern- mental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborat
5、es closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. 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 Cou
6、ncil. They are approved in accordance with IS0 procedures requiring at least 75 % approval by the member bodies voting. International Standard IS0 7999 was prepared by Technical Committee ISO/TC 39, Machine tools. Annex A of this International Standard is for information only. international Organiza

8、m IHS -,-,- INTERNATIONAL STANDARD IS0 7988 : 1988 (El Woodworking machines - Double-end tenoning machines - Nomenclature and acceptance conditions 1 Scope This International Standard specifies the nomenclature ap- propriate to each part of the machine and, with reference to IS0 230-1, the geometric
9、al and practical tests for double-end tenoning machines, and gives the corresponding permissible deviations which apply to machines of general purpose use and normal accuracy. NOTE - In addition to terms used in the three official IS0 languages (English, French and Russian), this International Stand
10、ard gives the equivalent terms in the German, Spanish, Italian and Swedish languages; these are published under the responsibility of the member bodies for Germany, F.R. (DIN), Spain (AENOR), Italy (UNI) and Sweden ISIS). However, only the terms given in the official languages can be considered as I
11、S0 terms. This International Standard deals only with the verification of the 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, etc.) which shou
12、ld generally be checked before the accuracy is tested. This International Standard applies to those machines designated by the number 82.2 in IS0 79841). 2 Normative reference The following standard contains provisions which, through reference in this text, constitute provisions of this Internationa
13、l Standard. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this International Standard are encour- aged to investigate the possibility of applying the most recent edition of the standard listed below. Members of
14、IEC and IS0 maintain registers of currently valid International Standards. IS0 230-I : 1986, Acceptance code for machine tools - Part 1: Geometric accuracy of machines operating under no-load or finishing conditions. 3 Preliminary remarks 3.1 In this International Standard all dimensions and permiss
15、- ible deviations are expressed in millimetres. 3.2 To apply this International Standard, reference should be made to IS0 230-1, especially for installation of the machine before testing, the warming up of the main spindle and other moving parts, and the description of the measuring methods. The mea
16、suring instruments shall not permit measurement errors over I/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 way defines the practical order of testing. In order to make mounting of instruments an
17、d 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 choose, in agreement with the manufacturer, those tests relating to the properties w
18、hich are of interest to him, but these tests shall 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 tolerance for a measuring range different from that given in this International Standard (
19、see subclause 2.311 in IS0 230-11, it should be taken into con- sideration that the minimum value of the tolerance is 0,Ol mm. 1) IS0 7% : 1989, Woodworking machines - Technical classification of woodworking machines and auxiliary machines for woodworking. 1 Copyright International Organization for
