There is a lack of global agreement on SSL test standards and mutual recognition of regional accreditation programmes. This situation creates trade barriers and increases the costs of doing business, slowing down the adoption of LEDs and associated energy savings. 

The SSL Annex seeks collaboration with accreditation bodies worldwide in support of mutual recognition of regional accreditation of SSL product testing. Coordination of international accreditation of SSL testing laboratories is important for traceability of SSL products. By comparing 110 LED testing laboratories around the world, the 2013 Interlaboratory Comparison (see Final Report) produced a common proficiency test that:

  • Testing laboratories can use to compare their LED product testing performance (integrated sphere) with other laboratories around the world and
  • Regional accreditation bodies can use in support of mutual recognition of other accreditation programmes, thereby lowering product testing costs.

The SSL Annex is now working on an interlaboratory comparison (IC 2017) for goniophotometers, which is based on the test method CIE S 025/E:2015.  For more information on this work, please visit the News Item and the Registration Page for IC 2017.
