本标准适用于由航空航天标准规定的金属材料的不间断恒载拉伸蠕变应变和应力破裂试验。它定义了可能需要确定的属性以及用于描述测试和测试的术语。它规定了试件的尺寸和试验方法。符合本标准的蠕变应变和应力破裂试验的持续时间应小于10 000 h，温度不超过100℃。 本标准也适用于超过10 000 h的测试持续时间和/或超过1100°C的测试温度的金属材料，前提是制造商和采购方之间达成了以前的协议

This standard applies to uninterrupted constant-load tensile creep strain and stress-rupture testing of metallic materials governed by aerospace standards. It defines the properties that may need to be determined and the terms used in describing tests and test pieces. It specifies the dimensions of test pieces and the method of testing. The duration of the creep strain and stress-rupture tests complying with this standard shall be less than 10 000 h and at temperatures not exceeding 1 100 °C. This standard may also apply to metallic materials for test durations exceeding 10 000 h and/or for test temperatures exceeding 1 100 °C providing that previous agreement has been reached between the manufacturer and the purchaser.
