The British Standards BS2050 (1978) and DIN 22104 are the recognized specifications which cover the test procedures and accepted levels for rubber and Polyurethane timing belts relating to antistatic properties.
TransDev has developed a post manufacturing electrically conductive black coating which complies with the above specifications and is available on all Polychloroprene type rubber timing belts and currently on 3 different Polyurethane belt substrates (All BRECO®/BRECOFLEX® & SYNCHROFLEX® belts).
The antistatic timing belt is, therefore, a specific and new solution for all those who operate in hazardous industrial fields, where static build-up would present potentially disastrous circumstances (e.g. chemical, mining, oil and electronics). Elimination of RFI also makes for easier FCC and CE certification. It is obvious that during the working life of the drive that the eventual reduction of conductivity means that the testing of the belt’s resistance in a planned maintenance schedule is important. TransDev is also able to supply you with a belt surface conductivity tester.
