April 2020, BTTG lab (UK) has tested Gefest-420 fr fabric to the new version of safety standard for Protective clothing for use in welding and allied processes. Gefest-420 certified to EN ISO11611 CLASS 2 welding clothing.
EN 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.
This standard has two classes. EN ISO 11611 includes two heat transmission tests, both of which should be carried out on material from the test garment, i.e. impact of molten metal droplets, and resistance to the transfer of radiant heat. The test results are classified according to the performance achieved into either class 1 or class 2 .
Class 1 – Protects against less hazardous welding techniques and situations, causing lower spatter and radiant heat
End Use (Manual welding with light spatter and drop; such as Gas, TIG, MIG welding (Low current) spot welding)
Environmnet (Operating machines such as oxygen cutting, plasma cutting, resistance and bench welding)
Class 2 – Protects against riskier welding techniques and situations, which causes higher levels of spatter and radiant heat
End Use (Manual welding with heavy spatter and drop; such as plasma cutting, oxygen cutting and thermal spraying Operating machines in confined spaces or in constrained positions)
Environmnet (Clothing will also minimise the possibility of electrical shock by short term, accidental contact with live conductors at voltages up to approximately 100V dc.)
According to EN ISO 11611:2015, Gefest-420 has been successfully tested to the following tests:
Gefest-420 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 is extremely useful in protective overalls, bibs or aprons of welders and other workers letting molten metal drops go off easily from the smooth surface of the fabric.
You can find all the certificates and additional information on the Gefest-420 product page.
