Proficiency Testing for Global Solar Collector Certification

The IEA-SHC launched Task43 about 3 years ago. Now all of the preparations for the program are almost ready and practical application for certification will begin. In order to increase the confidence of all of the interested parties in the testing report and certified documents, peer review will be undertaken by the global solar collector networks for laboratories, certification bodies and inspection agencies. This article is regarding proficiency testing as an important method to assess the laboratory's competence. The following are the key points during the proficiency testing procedure, namely homogeneity and stability for samples, assigned values and uncertainty, and standard deviation for proficiency assessment. Based on ISO/IEC 17043:2010, ISO 13528:2005 and ISO/ FDIS 9806:2013 the proficiency testing scheme for solar collectors is discussed in this article in detail.
