This machine mainly tests and evaluates safety shoes, protective shoes and professional shoes with anti-static function, and evaluates whether the test specimen has antistatic performance through the tested specimen, the closed circuit composed of steel balls and copper and copper plates, the resistance of the test specimen, the antistatic and insulating resistance range values of the test specimen at a certain standard voltage. The test can complete the antistatic performance of protective shoes/soles according to European standards, national standards, plus marks, and American standards. 【Relevant Standards】

GB/T20991-2007, EN ISO20344-2012, CSA/CAN-Z195, SATRA, GB/21146-2007 and other standards.
