Electrical Matting Insulating Rubber ASTM D178 ANSI JS.7 7.5kV
SM557 is a high quality fine ribbed rubber insulating matting which is fully certified to meet American National Standard ASTM D178 Type 2, Section 5:
- Class 5.1.2.1-A O-Zone Resistant,
- Class 5.1.2.2-B Flame Resistant
- Class 5.1.2.3-C Oil Resistant.
The ASTM D178 Class 1 electrical matting is fully certified and tested to 20kV with a recommended safety working voltage of 7.5kV.
Additionally the insulating electrical matting has a fine ribbed, anti-slip surface pattern on one side and a cloth impression finish on the reverse side ensuring safe electrical working conditions for users.
SM557 insulating matting is available in stock lengths of 10m x 0.91m with a thickness of 4.5mm (SM557-01), 6.5mm (SM557-02) or 10mm (SM557-03) and on request can be produced in cut length sizes and a variety of colours or with flame retardant, low emission grade materials.
