IC 2023 Nucleus Lab Comparison Report – Part 2 Published

Today, the SSL Annex has published the Nucleus Laboratory Comparison report – Part 2 of the 2023 Interlaboratory Comparison (IC 2023).  IC 2023 is investigating the degree of agreement in the measurements of temporal light modulation (TLM) quantities, in particular, short-term flicker indicator (PstLM), and stroboscopic effect visibility measure (SVM).

IC 2023 consists of two parts: Part 1 used a set of four LED lamps with different TLM characteristics as comparison artefacts; Part 2 used a TLM waveform generator programmed with five different waveforms. Part 1 was designed to comply with ISO/IEC 17043 to serve as a proficiency test for SSL testing accreditation programmes that recognise this comparison as was done in IC 2013 and IC 2017. Part 2 was offered as an option for participants to provide further technical study for more varieties of waveforms that are not available with lamps.

Laboratories that conduct testing of LED lamps and luminaires for these TLM quantities have participated in IC 2023. This comparison was organised primarily to investigate the degree of agreement in the measurements of these TLM quantities among the participants as technical study as well as to provide verification of each participating laboratory’s measurement capabilities. This report presents the results of the comparison between the Reference Laboratories of the TLM generator artefact (ART-5) in IC 2023.
