What is BS EN 62059-32-1 – Stability of metrological characteristics of electricity metering equipment about? 
The stability of metrological characteristics is one important aspect of durability.
BS EN 62059 is a European Standard that discusses electricity metering equipment. 
BS EN 62059-32-1 is a one of the parts in the series that covers general aspects of the dependability and durability of electricity metering equipment based on elevated temperature testing. The stability of metrological characteristics is one important aspect of durability.
BS EN 62059-32-1 specifies a method for testing the stability of metrological characteristics of electricity meters, by operating a test specimen at the upper limit of the specified operating range of temperature, voltage and current for an extended period.
BS EN 62059-32-1 is applicable to all types of electricity meters in the scope of IEC TC 13.
Note: Functional performance other than the accuracy of energy measurement is out of the scope of BS EN 62059-32-1.
Who is BS EN 62059-32-1 - Stability of metrological characteristics of electricity metering equipment for?  
BS EN 62059-32-1 on stability of metrological characteristics of electricity metering equipment is relevant to:  
- Electricity metering manufacturers and purchasers 
- Anyone involved in design, installation, and maintenance of electric metering equipment
- Power distribution and transmission companies  
- Local authorities  
- Inspection authorities 
- Regulatory bodies 
- Engineers 
Why should you use BS EN 62059-32-1 - Stability of metrological characteristics of electricity metering equipment? 
When it comes to electricity supply systems, performance and reliability of electricity metering equipment is essential for fair and accurate meter readings.  Electricity meters are products designed for high reliability and durability to operate continuously for extended periods without supervision. To manage metering assets effectively, it is important to have tools for predicting and estimating life characteristics of various types.
It is, for this reason, BS EN 62059-32-1, walks you through a test method to evaluate one important aspect of durability, the stability of metrology characteristics, by operating a test specimen at the upper limit of the specified operating range of temperature, voltage and current for an extended period.
If the MUT passes the test, this gives a reasonable level of confidence that the meter type tested is free from serious design errors and material flaws that may prevent it from maintaining its specified accuracy for the period of use estimated by the manufacturer.
As a result, if you are a manufacturer of electricity metering equipment, compliance with BS EN 62059-32-1 guidelines can ensure your products provide service over longer period of time facilitate provision of accurate meter readings.
