Abstract: In the design of any electrotechnical product,the hazards of abnormal heat need to be considered. The results of ball pressure test is one of the basis for the selection of non-metallic materials In the process of the entire product testing certification; and it is chosen as proficiency testing projects in domestic and foreign laboratories which shows the importance of the ball pressure test ability. The testing process of ball pressure is complicated and there are many factors influencing the results of ball pressure test; this paper analyzed using devices and operation methods in the process of ball pressure test according to new standard GB/T 5169.21-2017 and IEC 60695-10-2:2014.

Key words: Testing certification, Ball pressure test, Proficiency testing, Factors
