本文件定义了四项测试:-环境温度变化误差（ETVE）测试；-旋转主轴引起的热变形试验；-线性轴移动引起的热变形试验；-由部件旋转运动引起的热变形试验。移动线性轴引起的热变形试验（见第7条）仅适用于数控（NC）机床，旨在量化热膨胀和收缩以及结构角变形的影响。出于实际原因，第7条中所述的试验方法适用于直线轴长度不超过2000 mm的机器。如果它们用于轴长超过2000 mm的机器，则在每个轴的正常范围内选择代表性长度为2000 mm的试验。这些试验符合ISO/TR 16015:2003，A.4.2中所述的漂移试验程序，适用于机床，特别考虑了移动线性部件的热变形和移动旋转部件的热变形。在配备热效应补偿的机床上，这些试验证明了由于热膨胀系数的不确定性而产生的标称热膨胀的任何不确定性，以及由于温度测量而产生的任何长度不确定性。

This document defines four tests:— an environmental temperature variation error (ETVE) test;— a test for thermal distortion caused by rotating spindles;— a test for thermal distortion caused by moving linear axes;— a test for thermal distortion caused by rotary motion of components.The tests for thermal distortion caused by moving linear axes (see Clause 7) are applicable to numerically controlled (NC) machines only and are designed to quantify the effects of thermal expansion and contraction as well as the angular deformation of structures. For practical reasons, the test methods described in Clause 7 apply to machines with linear axes up to 2 000 mm in length. If they are used for machines with axes longer than 2 000 mm, a representative length of 2 000 mm in the normal range of each axis is chosen for the tests.The tests correspond to the drift test procedure as described in ISO/TR 16015:2003, A.4.2, applied for machine tools with special consideration of thermal distortion of moving linear components and thermal distortion of moving rotary components. On machine tools equipped with compensation for thermal effects these tests demonstrate any uncertainty in nominal thermal expansion due to uncertainty of coefficient of thermal expansion and any uncertainty of length due to temperature measurement.
