Price based on 11 pages Copyright International Organization for Standardization Not for Resale FOREWORD ISO (the International Organization for Standardization) is a worldwide federation of national standards institutes (ISO Member Bodies). The work of developing International Standards is carried out through ISO 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, governmental 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 ISO Council. International StandardIS0 3190 was drawn up by Technical Committee ISO/TC 39, Member Machine the Bodies tools, and circulated to in November 1973. It has been approved by the Member Bodies of the following countries : Australia Hungary Sweden Austria india Switzerland Belgium Italy Thailand Bulgaria Japan Turkey Czechoslovakia New Zealand United Kingdom Egypt, Arab Rep. of U.S.A.

It does not apply to the testing of the running of recommended accuracy of testing equipment. the machine (vibrations, abnormal noises, stick-slip motion The sequence in which the geometrical tests are given is of components, etc.), or to machine characteristics (speeds, related to the sub-assemblies of the machine and this in no feeds, etc.) which should generally be checked before way defines the practical order of testing. In order to make testing accuracy. the mounting of instruments or gauging easier, tests may be As there is great variety in the configuration of these applied in any order. machines, the most common being When inspecting a machine, it is not always possible, or box type and variable height table machines, necessary, to carry out all the tests given in this International Standard. It is up to the user to choose, in - box type and fixed height table machines, agreement with the manufacturer, those tests relating to the existing elements of the machine or to the properties which bridge machines,
