Frequently Asked Questions

CLC/SR 85 is a Technical Committee within CLC. It is named "Measuring equipment for electrical and electromagnetic quantities". This committee has published 12 standards.

CLC/SR 85 develops CLC standards in the area of V17 - ELECTRONIC MEASURING EQUIPMENT. Currently, there are 12 published standards from this technical committee.

CLC is a standardization organization that develops and publishes standards to support industry, commerce, and regulatory requirements.

A Technical Committee (TC) in CLC is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
