FR fabric Gefest-480 updates EN ISO 11612 to version:2015

January 2018, AITEX lab (Spain) has tested Gefest-480 fr fabric to the new version of safety standard for Protective clothing – Clothing to protect against heat and flame. Gefest-480 confirmed its compliance to ISO EN 11612:2015 and received a new certificate, which you can see below.

According to EN ISO 11612:2015, Gefest-480 has been successfully tested to the following tests:

  1. Heat Resistance (ISO 17493:2000) – performance level – PASS

    Gefest-480 results for samples and after 5 washing cycles at 60ºC, according to the standard ISO 6330:2012, method 6N, F drying (tumble dry)

ISO 12127-1:2007 specifies a test method for the determination of contact heat transmission. It is applicable to protective clothing (including hand protectors) and its constituent materials intended to protect against high contact temperatures. ISO 12127-1:2007 is restricted to contact temperatures between 100°C and 500°C.

The performance requirements set out in ISO 11612:2015 are applicable to garments which could be worn for a wide range of end uses, where there is a need for clothing with limited flame spread properties and where the user can be exposed to radiant or convective or contact heat or to molten metal splashes.

Gefest-480 flame retardant protective fabric is purposed for professional welders clothing in different areas such as Machinery, Metallurgy, Oil and Gas Pipeline construction, Automotive etc. 
Satin weave of Gefest-480 is extremely useful in protective overalls, bibs or aprons of welders letting molten metal drops go off easily from the smooth surface of the fabric. 
Made of natural fibers it is very soft and comfortable to wear and at the same time the fabric protects from the risks of Flash Fire and Electric Arc.

You can find all the certificates and additional information on the Gefest-480 product page.
