The EN ISO 11611 standard specifies the minimum basic security requirements and test methods for protective clothing and processes related to comparable risks.
This kind of protective clothing is dedicated to protecting the wearer against splashes (small molten metal splashes), short flame contact time, radiant heat from an electric arc used for welding, and related processes. It also minimises the potential for electric shock due to a short circuit (accidental, short-brief contact with electrical conductors at voltages of up to about 100 V)
