EN ISO 11611 Protective clothing for use in welding and allied processes
Supersedes EN 470-1:1995
The protective clothing is intended to protect the wearer against small splashes of molten material, short contact time with flame, radiant heat from ARC, the clothing minimizes the possibility of electrical shock by short accidental contact with live electrical conductors up to 100 V d.c. voltage.
The following parameters are used:
PROTECTIVE CLOTHING FOR USE IN WELDING AND ALLIED PROCESSES.
The fabric has been tested by EN ISO 11611:2007 standards for a number of qualities including : LIMITED FLAME SPREAD, HEAT TRANSFER. IMPACT OF MOLTEN METAL SPLASHES
Class 1 : protects against less hazardous welding techniques and situations, which
produce less spatter and radiant heat.
Class 2: protects against more hazardous welding techniques and situations, which
produce more spatter and radiant heat.
А indicates that the garment meets the requirements for limited flame spread.
А1 — surface ignition method,
А2 — edge ignition method.
А1 + А2 — both methods.
EN ISO 11611 Protective clothing for use in welding and allied processes
ISO 11611:2007 specifies minimum basic safety requirements and test methods for protective clothing including hoods, aprons, sleeves and gaiters that are designed to protect the wearer’s body including head (hoods) and feet (gaiters) and that are to be worn during welding and allied processes with comparable risks. For the protection of the wearer’s head and feet, ISO 11611:2007 is only applicable to hoods and gaiters. ISO 11611:2007 does not cover requirements for hand protection.
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 the arc, and minimizes the possibility of electrical shock by short-term, accidental contact with live electrical conductors at voltages up to approximately 100 V d.c. in normal conditions of welding. Sweat, soiling or other contaminants can affect the level of protection provided against short-term accidental contact with live electric conductors at these voltages.
ISO 11611:2007 specifies two classes with specific performance requirements, i.e. Class 1 being the lower level and Class 2 the higher level.
Class 1 is protection against less hazardous welding techniques and situations, causing lower levels of spatter and radiant heat.
Class 2 is protection against more hazardous welding techniques and situations, causing higher levels of spatter and radiant heat.
For adequate overall protection against the risks to which welders are likely to be exposed, personal protective equipment (PPE) covered by other standards should additionally be worn to protect the head, face, hands and feet.
