Abstract: In order to understand the capability of working noble metal thermocouple after implementation the JJG 141——2013 Verification Regulation of Working Noble metal Thermocouple. China National Accreditation Service for Conformity Assessment（CNAS） organized the proficiency test of working noble metal thermocouple.88 laboratories form 28 provinces/cities/municipals took part in the proficiency test.In this paper， the implementation process of the test was described， including project design，sample preparation，homogeneity stability test，result statistic and analysis， etc. The resulted showed that 98.86% laboratories have satisfactory results.In conclusion，most laboratories taking part in the proficiency test have good competence in calibrating working noble metal thermocouple.
