August 2019, AITEX lab (Spain) has tested Etna fr fabric to the new version of safety standard for Protective clothing for use in welding and allied processes. Etna confirmed its compliance to ISO EN 11611:2015 and received a new certificate, which you can see below.
According to EN ISO 11611:2015, Etna has been successfully tested to the following tests:
- Limited Flame Spread (ISO 15025:2002, Method A) – performance level – A1
Etna 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
- Limited Flame Spread (ISO 15025:2002, Method A) – performance level – A2
Etna 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
- Fabric Tensile Strength and Elongation (EN ISO 13934-1:2013) – performance level – PASS
- Wrap: 1300N – PASS (must resist ≥ 400 N)
- Weft: 790N – PASS (must resist ≥ 400 N)
- Determination of Rupture elongation (EN ISO 13934-1:2013) – performance level – PASS
- Warp: 19% –PASS (must be ≥ 15N)
- Weft: 21,2% – PASS (must be ≥ 15N)
- Small Molten Metal Splash (ISO 9150:1988) – performance level – Class 2
- Average value Molten iron (g): > 28
| Class 1 | Minimum 15 drops |
| Class 2 | Minimum 25 drops |
- Radiant Heat (ISO 6942) – performance level – Class 1
- Average value for RHTI 24 (s): 14,8
Heat transfer index RHTI 24 | Class 1 | Class 1 |
| RHTI 24 | ≥ 7s | ≥ 16s |
- Vertical Resistance (EN 1149-2:1997) – performance level – Pass
- Average value: 2,27∙107
According to the Standard UNE-EN ISO 11611:2015, the vertical electric resistance must be greater than 105 Ohm
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.
Etna flame retardant fabric is made of 350 gsm cotton with antistatic yarn and designed for use in Metallurgy and other industries. This fabric is best used for protective jackets, pants, overalls and other FR clothing.
