ISO 14137:2015

ISO 14137:2015, with reference to ISO 230-1, ISO 230-2, and ISO 230-4, geometric tests, tests of accuracy and repeatability of numerically controlled positioning axes, machining test and circular test for general purpose and normal-accuracy wire electro-discharge machines (wire EDM). It also specifies the applicable tolerances, corresponding to the above-mentioned tests.
ISO 14137:2015 is applicable to cross-slide table type machines and double-column type machines.
ISO 14137:2015 deals only with the verification of accuracy of the machine. It does not apply to the testing of the machine operation (vibrations, abnormal noises, stick-slip motion of components, etc.) nor to the checking of its characteristics (such as speeds, feeds, etc.), which should generally be checked before the testing of the accuracy.
ISO 14137:2015 provides the terminology used for the principal components of the machine and the designation of the axes with reference to ISO 841.
