BS EN 1499 specifies a test method simulating practical conditions for establishing whether a product for hygienic handwash reduces the release of transient microbial flora on hands when used to wash the artificially contaminated hands of volunteers

A description of achievable uncertainty and rules for the presentation of the calibration data are provided

Testing of insulating stand-offs and insulating down-conductors components for an explosive atmosphere is not covered by this document
