本文件规定了适用于分析数据的程序，当转换为数值的对数时，这些数据具有正态分布或偏斜分布。它旨在与玻璃增强热固性塑料（GRP）管道或配件的测试方法和参考标准一起使用，以分析随时间变化的性能。然而，它也可以用于其他数据的分析。指定了两种方法，根据数据的性质使用这两种方法。使用这些技术的外推通常从大约10？000？h到50的属性预测？年，这是典型的最大外推时间。本文档仅涉及数据分析。参考标准和/或测试方法涵盖了收集数据的测试程序、所需样品数量和收集数据的时间段。条款？6讨论了数据分析方法如何应用于产品测试和设计。

This document specifies procedures suitable for the analysis of data which, when converted into logarithms of the values, have either a normal or a skewed distribution. It is intended for use with test methods and referring standards for glass-reinforced thermosetting plastics (GRP) pipes or fittings for the analysis of properties as a function of time. However, it can also be used for the analysis of other data.

Two methods are specified, which are used depending on the nature of the data. Extrapolation using these techniques typically extends a trend from data gathered over a period of approximately 10 000 h to a prediction of the property at 50 years, which is the typical maximum extrapolation time.

This document only addresses the analysis of data. The test procedures for collecting the data, the number of samples required and the time period over which data are collected are covered by the referring standards and/or test methods. Clause 6 discusses how the data analysis methods are applied to product testing and design.
