Electricity metering equipment - Dependability - Part 31-1: Accelerated reliability testing - Elevated temperature and humidity (IEC 62059-31-1:2008, IDT)
This Malaysian Standard provides one of several possible methods for estimating product life characteristics by accelerated reliability testing.
Acceleration can be achieved in a number of different ways. In this particular standard, elevated, constant temperature and humidity is applied to achieve acceleration. The method also takes into account the effect of voltage and current variation.
Of course, failures not (or not sufficiently) accelerated by temperature and humidity will not be detected by the application of the test method specified in this standard.
Other factors, like temperature variation, vibration, dust, voltage dips and short interruptions, static discharges, fast transient burst, surges, etc. - although they may affect the life characteristics of the meter - are not taken into account in this standard; they may be addressed in future parts of the MS IEC 62059 series.
This Malaysian Standard is applicable to all types of metering equipment for energy measurement
