DC Metering Technical Standards Committee
Basic Charter:
This standard establishes acceptable performance criteria for revenue grade dc watthour meters and demand meters. Accuracy class designations, current class designations, voltage ratings, environmental tests, and immunity tests are covered.
Test procedures for voltage and current sensors that are separate (transducers) from the meter are also covered. This document is designed as a reference for those concerned with the design of dc electricity metering, such as utilities, manufacturers, and regulatory bodies, operators / service providers.
