FR fabric Gefest-480 updates EN ISO 11611 to version :2015

January 2018, AITEX lab (Spain) has tested Gefest-480 fr fabric to the new version of safety standard for Protective clothing for use in welding and allied processes. Gefest-480 confirmed its compliance to ISO EN 11611:2015 and received a new certificate, which you can see below.

According to EN ISO 11611:2015, Gefest-480 has been successfully tested to the following tests:

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

    Gefest-480 results for new samples and after 5 washes @60ºC ISO 6330:2012, method 6N, F drying (tumble dry)

  • Flaming to top or either side edge: No – PASS
  • Hole formation: No – PASS
  • Loose waste: No – PASS
  • After flame time (s): No – PASS
  • Afterglow time (s): No – PASS

 

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

    Gefest-480 results for new samples and after 5 washes @60ºC ISO 6330:2012, method 6N, F drying (tumble dry)

  • Flaming to top or either side edge: No – PASS
  • Hole formation: No – PASS
  • Loose waste: No – PASS
  • After flame time (s): No – PASS
  • Afterglow time (s): No – PASS

 

  1. Determination of Breaking Strength and Elongation (EN ISO 13934-1:2013) – performance level  PASS
  • Wrap: 2400N PASS (must resist ≥ 400 N)
  • Weft: 1100N PASS (must resist ≥ 400 N)

 

  1. Determination of Tear Resistance (EN ISO 13937-2:2000) – performance level – PASS
  • Warp 110NPASS (must be ≥ 15N)
  • Weft 140NPASS (must be ≥ 15N)

  • Average value for RHTI 24 (s): 16,8

Heat transfer Index RHTI 24

Class 1

Class 2

RHTI 24

 ≥ 7s

≥ 16s

ª: Heat transfer index, as defined in ISO 6942

 

  1. Small Molten Metal Splash (ISO 9150:1988) – performance levelClass 2
  • Average value Molten iron (g): > 25
Class 1 Minimum 15 drops 
Class 2 Minimum 25 drops 

 

  1. Vertical Resistance EN 1149-2:1997)  – performance level PASS
  • Vertical Resistance (Ohm): 1,95∙106

According to the Standard UNE-EN ISO 11611:2015, the vertical electric resistance must be greater than 10Ohm

 

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.

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.
