We are producer of the electrical insulating matts class 2, which complies with international norm PN-IEC 61111:2002/A1:2004 

Each roll of the product has included protocol with voltage test performed.

Electrical insulating matt is entirely subjected to the voltage test using alternating test voltage of 20 kV.

The effective value of AC voltage withstand is a minimum of 30 kV.
 
Electrical insulating matt is resistant to:
* acid – test according to PN-IEC 61111 norm in H2SO4 23o/8h
* oil – test according to PN-IEC 61111 norm in oil no. 1 70oC/24h
* low temperature – test according to PN-IEC 61111 norm in -25oC/1h

The electrical insulating matts are manufacter as standard grey color with dimensions:
* width: 1220 ± 25mm;
* length: 1.00 ÷ 8.0m;
* thickness: 5 ± 0,5mm
