Result Summary of LED Bulb Interlaboratory Comparison in Taiwan

Interlaboratory comparison is organization, performance and evaluation of measurements or tests on the same or similar items by two or more laboratories in accordance with predetermined conditions, which is the way to demonstrate the measurement capability of each laboratory. In order to understand the LED bulb measurement capability of each laboratory in Taiwan, CMS/ITRI held a LED bulb interlaboratory comparison scheme. This activity can help the participants to understand the differences of their measurement capabilities compared with others and then seek the solution to improve their measurement competence. This LED bulb interlaboratory comparison scheme was carried out according to ISO/IEC 17043:2010. Percent difference |D%| was chosen as the performance statistic to indicate the measurement capabilities of participants, and the measured values of National Measurement Laboratory (NML), R.O.C. were used as the assigned values. From the analysis of this LED bulb interlaboratory comparison, most of participants’ results were satisfactory, which implied that most of LED bulb test laboratories in Taiwan have good measurement competence.
