DALI standard IEC 62386

IEC 62386 - the international standard for DALI technology

IEC 62386, the international DALI standard, is published in multiple Parts by the International Electrotechnical Commission (IEC). Published Parts of IEC 62386 can be purchased by visiting the IEC website.

The table below shows the status of different Parts of IEC 62386. Parts labelled as "in progress" are being developed by the IEC working group (WG11 of TC34) that is responsible for writing and maintaining IEC 62386.

What is DALI-2? DALI-2 is based on version 2 of IEC 62386, which includes control devices (Part 103 and Parts 3xx) for the first time. All new Parts of the standard will be published as DALI-2 versions. Some (but not all) older Parts will be updated to DALI-2.

What is DiiA's role? DiiA develops testing procedures, known as test sequences, which enable companies to show compliance of their products with different Parts of the DALI-2 standard. The current status of test sequences is shown in the table below.

Our Timeline shows the planned priority for test-sequence development >> Timeline

Creation of DALI-2 test sequences relies on input from DiiA members, and is influenced by member priorities and market demand. Some Parts of DALI version-1 are unlikely to be included in the DALI-2 certification program.
