ISO 13041-8:2004参照ISO 230-3规定了适用于评估数控（NC）车床和车削中心机床结构和定位系统（长度不超过2000 mm）热变形的试验。ISO 13041-8:2004定义了三项测试，分别是:环境温度变化误差测试、旋转主轴引起的热变形测试和移动线性轴引起的热变形测试

ISO 13041-8:2004 specifies, with reference to ISO 230-3, the tests which apply for the evaluation of thermal distortions of the machine structure and positioning system, up to 2 000 mm in length, of numerically controlled (NC) turning machines and turning centres. ISO 13041-8:2004 defines three tests which are: the environmental temperature-variation error test, the test for thermal distortion caused by a rotating spindle, and the test for thermal distortion caused by moving linear axes
