How does DALI-2 certification differ from current DALI compliance testing?

View answer

The DALI-2 certification program is based on version 2 of the IEC 62386 standard for DALI technology, and involves verification of test results via a robust web-based tool. Current DALI version 1 compliance testing is based on self-declaration without verification of results. As well as covering many different product types, including control devices and input devices, DiiA version-2 certification offers the promise of improved interoperability of products from different manufacturers.

Why did you form a new alliance?

View answer

DiiA was formed in response to industry calls for a global, open, not-for-profit certification program based on the latest version of IEC 62386. It was felt that a new alliance was the best way to enable companies to bring their next-generation, certified DALI products to market in a timely and efficient manner.

Will you use the current DALI logo for DiiA certification?

View answer

The DiiA certification program will use the DALI-2 logo as its Certification Mark, to enable differentiation from the current DALI version-1 program. The new DALI-2 logo indicates enhanced functionality and interoperability of products. It also represents independent verification of test results; this is a foundation of the DiiA program but not part of DALI version-1 compliance testing, which is based on self-declaration.

DiiA membership gives access to the DALI-2 certification program, as well as up-to-date test sequences for both DALI-2 and DALI version 1. These benefits are not available to former DALI-AG members. DiiA membership also provides the right to use the DALI trademarks and logos.

Can companies such as luminaire makers use the DiiA logo if they do not certify their own DALI-based products?

View answer

DiiA will support luminaire manufacturers and other companies that do not certify products themselves but make use of certified DALI components as part of their products. DiiA will grant these companies a license to use its trademarks in accordance with the DiiA Trademark Guidelines. For this purpose, companies can register via the DiiA website; there is no registration fee or license fee. To preserve the integrity of its certification program, DiiA will monitor the use of its trademarked logos and Certification Marks, and will take steps to prevent improper use in the marketplace.

Will you continue to support the current DALI self-declaration program?

View answer

Yes, DiiA will provide a program for its members that supports self-declaration and registration of products that have been tested for compliance with DALI version 1. DiiA members will be able to use the current DALI version-1 logo on products.

What happened to the DALI-AG working party?

View answer

ZVEI, the German Electrical and Electronic Manufacturers' Association, provided a range of services related to DALI version-1 through its DALI working party (also known as DALI-AG). This organization was dissolved by ZVEI in late March 2017. There are no organization links between ZVEI and DiiA. The DALI trademarks and logos were acquired on behalf of DiiA from ZVEI.
