November 2019, AITEX lab (Spain) has tested Murano-250 fr fabric to the new version of safety standard for Protective clothing for use in welding and allied processes. Murano-250 confirmed its compliance to ISO EN 11611:2015 and received a new certificate, which you can see below.
According to EN ISO 11611:2015, Murano-250 has been successfully tested to the following tests:
- Limited Flame Spread (ISO 15025:2002, Method A) – performance level – A1
Murano-250 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

- 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
- Determination of dimensional change in domestic washing and drying (ISO 5077:2008) – performance level – PASS

| Direction | Dimensional change (%) |
| Warp | -2,0 |
| Weft | -2,0 |
- Fabric Tensile Strength and Elongation (EN ISO 13934-1:2013) – performance level – PASS
- Wrap: 780N – PASS (must resist ≥ 400 N)
- Weft: 600N – PASS (must resist ≥ 400 N)
- Determination of Tear Resistance (EN ISO 13937-2:2000) – performance level – PASS
- Warp: 54N –PASS (must be ≥ 15N)
- Weft: 36N – PASS (must be ≥ 15N)
- Small Molten Metal Splash (ISO 9150:1988) – performance level – Class 1
- Average value Molten iron (g): > 20
| Class 1 | Minimum 15 drops |
| Class 2 | Minimum 25 drops |
- Radiant Heat (ISO 6942) – performance level – C1
- Average value for RHTI 24 (s): 14,3

Heat transfer index RHTI 24 |
Class 1 |
Class 1 |
| RHTI 24 | ≥ 7s | ≥ 16s |
- Vertical Resistance (EN 1149-2:1997) – performance level – Pass
- Average value: 4,33∙106
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.
Murano-250 is a modacrylic fabric for fr-clothing. Made with modacrylic-cotton blend it has inherently flame retardant composition. It also includes nylon for more durability and antistatic fibers to avoid static electricity. Murano-250 is a very comfortable and versatile fr-fabric for long lasting protective performance.
