Liaisons with external organizations

DiiA liaisons and collaborations

DiiA works with a number of external organizations:

 


IEC (International Electrotechnical Commission)

DiiA participates in the IEC work group WG 11 of TC 34. 

WG 11 develops and maintains IEC 62386, the international DALI standard.

DiiA provides Clarifications and Recommendations to WG 11, which are used by IEC in future updates of IEC 62386.

Separately, DiiA also writes new specifications, which are then provided to IEC to be incorporated into IEC 62386.

ANSI (American National Standards Institute)

DiiA is represented on the ANSI Accredited Standards Committee (ASC) C137 on Lighting Systems.

DiiA members contributed to the development of the new standard ANSI C137.4-2019 entitled “American National Standard for Lighting Systems—Digital Interface with Auxiliary Power.”

ANSI C137.4 is based on the DALI standard IEC 62386 with additional characteristics that are aligned with the D4i family of specifications from DiiA.
