IEC 62059-31 -1:2008, Part 31-1: Accelerated reliability testing - Elevated temperature and humidity, provides one of several possible methods for estimating product life characteristics by accelerated reliability testing. In this standard, elevated, constant temperature and humidity is applied to achieve acceleration. The method takes into account the effect of voltage and current variation. It is applicable to all types of metering equipment for energy measurement, tariff and load control in the scope of IEC TC 13.The method given in this standard may be used for estimating (with given confidence limits) product life characteristics of such equipment prior to and during serial production.This method may also be used to compare different designs.
