IEC and Zhaga sign liaison agreement

Posted on Tuesday December 2 2014, by Tim Whitaker

The Zhaga Consortium has signed a liaison agreement with IEC, the standards-development organization, in order to establish an active cooperation between the two organizations.

This is expected to result in IEC publications based on the Zhaga interface specifications, beginning with Zhaga Book 3, in conjunction with Book 1.

The International Electrotechnical Commission (IEC) is the world’s leading organization that prepares and publishes international standards for all electrical, electronic and related technologies.

The type-D liaison agreement has been signed between Zhaga and two IEC working groups (WGs). These are WG PRESCO, part of SC34A (the IEC subcommittee on Lamps) and WG COMEX, which is part of SC34C (the IEC subcommittee on Auxiliaries for Lamps, which includes lamp control gear).

As part of the liaison agreement, preparatory work is now underway to transfer Zhaga interface specification Book 3 into a Publicly-Available Specification (PAS).

A PAS is a publication responding to an urgent market need, and in this case represents a consensus in an industrial consortium external to IEC. The objective of a PAS is to speed up standardization in areas of rapidly-evolving technology.

IEC will work with the current Edition (1.3) of Zhaga Book 3, together with Zhaga Book 1 which contains information that is referenced by all the other Zhaga Books.  Once transferred to IEC, future amendments to Zhaga Books will be considered, commented on, and voted on according to IEC rules.

Zhaga’s mission is to develop and publish interface specifications (Books) for interchangeable LED light engines, but this does not include the development of international standards. Instead, the final phase of Zhaga’s Book Development Process is “maintenance by a standards-development organization (SDO)”.

The stated procedure is that Zhaga “intends to transfer all its Books to an SDO such as, for example, IEC. That transfer will take place once a Zhaga specification is stable and widely used.”

Zhaga is investigating the potential for other liaison agreements with IEC, in areas such as cap-holder systems for replaceable LED light engines.
