The development of proficiency testing programme for electrical and mechanical safety tests

The laboratory accreditation is essential for most consumer product testing providers. In the current laboratory accreditation criteria, interlaboratory correlation study or proficiency testing is one of the mandatory requirements. Proficiency testing can help to find out the weakness and potential errors sources of measurement in the testing providers. However, there is a problem of lack of electrical and mechanical proficiency testing programme in Hong Kong and South China region. This paper aimed to explain the development process of a proficiency testing programme that is suitable for electrical and mechanical safety tests. The process tested for homogeneity and stability of specimen will also be discussed in this paper.
