IEC TR 60493-3:20 17(E)阐明了如何使用少量样本进行统计分析。 当加速测试方法难以实施时，例如在测试样本（包括测试设备）的尺寸非常大或测试样本的成本很高的情况下，本文件将是有用的。通过使用户能够减少测试样本的数量来促进测试。

IEC TR 60493-3:2017(E) clarifies how a statistical analysis can be done with a small number of samples.
This document will be useful when the accelerated test method is difficult to carry out, for example in cases where the dimensions of test specimens (including test devices) are very large in scale or the cost of test specimens is high. Testing is facilitated by enabling users to reduce the number of test specimens.
