BS ISO 13041-1-2020 Test conditions for numerically controlled turning machines and turning centres Part 1: Geometric tests for machines with horizontal workholding spindle(s). 4.2 Reference to Iso 230 To apply this document, reference shall be made to ISO 2301:2012. ISO 230-7:2015, when required, especially for the installation of the machine before testing, warming up of the spindle and other moving components, description of measuring methods and recommended accuracy of testing equipment. Where the test concerned is in compliance with the specifications of ISO 230-1 and/or ISO 230-7, a reference to the corresponding clause of ISO 230-1, respectively ISO 230-7. is shown before the instructions in the ObservationsN block of the tests described below. Tolerances are given for each test (see Gi to G30). 4.3 Machine levelling Prior to conducting tests on a machine tool, the machine tool should be levelled according to the recommendations of the supplier/manufacturer (see ISO 230-1:20 12, 6.1.1 and 6.1.2). 4.4 Testing sequence The sequence in which the tests are presented in this document in no way defines the practical order of testing. In order to make the mounting of instruments or gauging easier, tests may be performed in any order. 4.5 Tests to be performed When testing a machine, it is not always necessary or possible to carry out all the tests described in this document. When the tests are required for acceptance purposes, it is up to the user to choose, in agreement with the supplier/manufacturer, the relevant tests relating to the components and/or the properties of the machine. These tests are to be clearly stated when ordering a machine. A simple reference to this document for the acceptance tests, without specifying the tests to be carried out, and without agreement on the relevant expenses, cannot be considered as binding for any contracting party. 4.6 Measuring instruments Measuring instruments indicated in the tests described below are only examples. Other instruments capable of measuring the same quantities and having the same, or a smaller, measurement uncertainty may be used. When a dial gauge is referred to, it can mean not only dial test indicators (DTI) but any type of linear displacement sensor such as analogue or digital dial gauges, linear variable differential transformer (LVDTs), linear scale displacement gauges, or non-contact sensors, when applicable to the test concerned. Similarly, when a straightedge is referred to, it can mean any type of straightness reference metrological standard, such...
