ISO 14137:2015，参考ISO 2301，ISO 2302和ISO 2304、几何测试、数控定位轴的精度和重复性测试、通用和普通精度线切割机（线切割机）的加工测试和圆形测试。它还规定了与上述试验相对应的适用公差。 ISO 14137:2015适用于十字滑台式机器和双柱式机器。 ISO 14137:2015仅涉及机器精度的验证。它不适用于机器操作的测试（振动、异常噪音、部件的粘滑运动等）。 )也不涉及其特性（如速度、进给等）的检查，通常应在精度测试之前进行检查。 ISO 14137:2015提供了机器主要部件使用的术语以及参考ISO 841的轴名称。

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.
