定义了获取和评估必要数据的程序，这些数据是为声称具有不同于国际公认性能的钢材的承压钢材建立长期应力断裂值所必需的。标准程序的目的是尽量减少由于所用数据的数量和持续时间以及分析数据的方法不同而在不同国家获得的长期估计数的任何差异。

Defines a procedure for obtaining and for assessing the data necessary to establish long-time stress rupture values for steels for pressure purposes for steels where properties different from those internationally agreed are being claimed. The purpose of a standard procedure is to minimize any differences in long-time estimates obtained in different countries due to differences in the quantity and duration of the data used and differences in the method of analysing the data.
