【 摘 要 】

Creepage distance and clearance testing are the basic testing items in the safety standards for almost all electrical and electronic products. A typical sample group is designed in this paper for the purpose of proficiency testing programmes. The sample group is composed of two kinds of circuit board. The length of the creepage distance of the two circuit boards in pollution degree 2 and 3 are the same but with different paths. This sample group includes three testing points. This sample group is designed beneficial for numerical statistics and avoiding the data complicity in the laboratory. It can be used for effective laboratory monitoring.
