British Standard BS921:1976

The British Standard BS921:1976 outlines the requirements for rubber matting for electrical purposes and specifies the construction materials, thickness, width and the testing conditions and results expected to meet the standard. BS921:1976 was withdrawn in January 2013 as it is conflicting with the current UK national standard of BS EN 61111:2009 for electrical insulating matting.
