Madeira-320 renews to ISO 11611:2015 certificate

November 2017. Our fr-fabric Madeira-320 has been re-certified for EN ISO 11611:2015. Due to this ISO certificate is valid only for 5 years, and the original testing was done in 2012, XM FireLine™ has tested this flame retardant fabric once again. The testing has been done at international lab AITEX (Spain).

ISO 11611:2015 specifies minimum basic safety requirements and test methods for protective clothing during welding and allied processes with comparable risks. This type of protective clothing is intended to protect the wearer against spatter (small splashes of molten metal), short contact time with flame, radiant heat from an electric arc used for welding and allied processes.

Madeira-320 is pure cotton flame-retardant fabric made of long-staple 100% cotton. It can be used for protective clothing of welders and for FR-clothing for different metal processing works in heavy machinery, automotive manufacturing, etc.

This fr-fabric is comfortable to wear and protects from the risks of flash fire and electric arc. Madeira-320 can be used for everyday flame-retardant workwear such as FR-pants, FR-jackets, FR-bibs, and FR-overalls.
According to EN ISO 11611:2015, Madeira-320 has been successfully tested to the following tests:

  1. Limited Flame Spread (ISO 15025:2002, Method A) – performance level – A1, A2

    Requisites to be met according to ISO 15025
