Guidance: In-service testing handbook for gas and electricity meters

The in-service testing (IST) handbook is a culmination of the IST group 1 and 2 report and the IST group 3 report. It is designed to provide stakeholders who are undertaking sample testing with an understanding of the sampling methodology, test processes, assessment methods and final assessment criteria. The handbook includes details of IST test stations that have been approved by the Office for Product Safety and Standards for the in-service testing of gas and electricity meters.

The handbook is a working document and amendments will be made when necessary as the implementation of IST develops over time.
