Title Antistatic safety footwear - Assessment of the main methods used to determine insulation resistance
Original title Chaussures de sécurité anti-électrostatique. Evaluation des principales méthodes de détermination de la résistance d'isolement [in French]
Bibliographic information 2nd Quarter 1990, No.139, Note No.1781-139-90, p.405-419. Illus. 9 ref.
Abstract The main methods used by manufacturers and test laboratories are DIN 4843, ISO 2878, draft ISO-TC 94/SC3 and tentative standard T 47-132. The test results provide useful information for users and manufacturers as to the suitability of antistatic footwear commercially available in France. To test the different methods used, an apparatus was developed and validated on the basis of on-foot tests (considered as a reference). 40 antistatic shoes representing most of the products on the market in France were tested to evaluate ISO, AFNOR and DIN methods. The results of these standard methods differed considerably from those obtained by the INRS: the differences varied from a ratio of 1 to 3 in the case of the ISO-TC 94/SC3 draft (the best of the standard methods currently in use) to a ratio of 1 to 360 in the case of the DIN 4843 method. The factors at the root of these differences were identified and studied by using the INRS method. Almost all the shoes tested were satisfactory from the point of view of electrical risk protection, but over 40% were too well insulated for adequate static charge dissipation.
