求助 UL 62 电线老化试验取样要求

有哪位知道，符合UL62 标准的电线进行老化试验时取样数量是多少？似乎UL1581中未提及，在哪个标准内有详细说明吗？

UL 2556
4.2.4 Preparation of specimens
4.2.4.1 Sample selection and number of specimens
Samples shall be taken from a wire, cable or cord, finished or during manufacture, at any time following
curing of the compound, where applicable.
A minimum of six specimens per sample shall be tested ²as received² and after accelerated aging or liquid
immersion. If the specimen breaks outside of the gauge marks or the grips of the mechanical
extensometer at a value below that specified as the acceptable minimum, the test results shall be
disregarded and the test shall be repeated with another specimen.

要求最少取6個樣板.
