The SSL Annex has today published the Nucleus Laboratory Comparison Report, which is an important milestone in the IEA 4E SSL Annex’s 2017 Interlaboratory Comparison (IC 2017). It is part of the quality assurance process of IC 2017, and serves as the link between the two Nucleus Laboratories and the individual participant laboratories’ test results by establishing equivalence between the measurements of the two nucleus labs – KILT in Korea and LNE in France.
The report demonstrates that these two laboratories are equivalent for the measurement of the samples tested. The report provides detail on labs, the sample tested, the procedure followed, the results measured, the calculation of correction factors and the comparison.
Participant laboratories in IC 2017 have been assigned to one of our two nucleus laboratories for comparison of their results. This report establishes that any participant’s results can be compared to those of any other participant in IC 2017, regardless of which of the two nucleus laboratories they were assigned to.
Following the publication of this report, the individual results reports will be issued to the participants. Following that process, we can all look forward to a very exciting comparison and analysis of 43 goniophotometers in 37 laboratories in 18 countries. A comparison of goniophotometers at this scale has never been done before, and we are excited about what lies ahead.
About the IEA 4E SSL Annex:
Launched in July 2010, the IEA-4E SSL Annex is a joint initiative of eight countries working together to address common challenges with SSL technologies. The Annex member countries understand there are significant advantages in engaging in an international collaboration and joint activities relating to SSL performance and quality. Sponsoring governments of the SSL Annex include Australia, Canada, Denmark, France, Korea, the Netherlands, Sweden and the United Kingdom. China also participates as an expert member of the SSL Annex. The Annex member countries believe that there are significant advantages in engaging in an international collaboration in order to develop a consensus on harmonised approaches to SSL performance and quality. The work of the SSL Annex spans a wide range of initiatives which can be found on the Annex’s website http://ssl.iea-4e.org/, including guidance for policy makers, quality and performance tiers and support for laboratory accreditation.
