EN STANDARDS

EN470-1:1995 is replaced with EN ISO 11611:2007

EN531:1995 is replaced with EN ISO 11612:2008

EN533:1997 is replaced with EN ISO 14116:2008

The new EN ISO standards are similar to the previous EN standards in terms of protection but they also require more complete garment tests. See grid below showing the difference in test requirements. All existing certificates of the EN standards remain valid. At present all new products being introduced to the range are tested and certified to the new EN ISO standards.

 

FLAME PROTECTION

 

The performance requirements set out in this international standard are applicable to garments which could be worn for a wide range of end uses, where there is a need for clothing with limited flame spread properties and where the user can be exposed to radiant or convective or contact heat or molten metal splashes.

Code A: Limited flame spread
Code B: Protection against Convective Heat - 3 levels
Code C: Protection against Radiant Heat - 4 levels
Code D: Protection against Molten Aluminium Splash - 3 levels
Code E: Protection against Molten Iron Splash - 3 levels
Code F: Protection against Radiant Heat - 3 levels

EN531:1995 - Harmonised European standard for protective clothing for industrial workers exposed to heat (excluding firefighters' and welders' clothing).

The following categorisation states performance levels:
A - limited flame spread
B - protection against convective heat
C - protection against radiant heat

EN61482-1-2:2007 (current) - (Identical to IEC 61482-2:2009 (new))
This European test method measures fabrics and garment systems abilities to protect against the thermal effects of an electric arc event.
Two protection classes:
Class 1 - 4kA
Class 2 - 7kA

This international standard specifies minimum basic safety requirements and test methods for protective clothing for use in welding and allied processes (excluding hand protection).

The international standard specifies two classes with specific performance requirements:
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.

EN1149:2008 - Is the harmonised European standard for protective clothing - protection against static electricity. This standard is not applicable for protection against mains voltages.

EN1149-1:1996 Test method for surface conducting fabrics
EN1149-3:2004 Charge decay test method for all fabrics
EN1149-5:2008 Performance requirements

This standard specifies the performance requirements for the limited flame spread properties of materials, material assemblies and protective clothing in order to reduce the possibility of the clothing burning and thereby itself constituting a hazard. Additional requirements for clothing are also specified.

Limited Flame Spread

EN13034:2005 +A1:2009 Protective Clothing against Liquid Chemicals
Performance requirements for chemical protective clothing offering limited protective performance against liquid chemicals (Type 6 and Type PB[6] equipment). This standard specifies the minimum requirements for limited use and re-usable limited performance chemical protective clothing. Limited performance chemical protective clothing is intended for use in cases of potential exposure to a light spray, liquid aerosols or low pressure, low volume splashes, against which a complete liquid permeation barrier (at a molecular level) is not required.
The standard covers both chemical protective suits (Type 6) and partial body protection (Type PB[6]). Chemical protective suits (Type 6) cover and protect at least the trunk and the limbs eg. one piece coveralls or two piece suits, with or without hood, boot-socks or boot covers. Partial body protection of similar limited performance (Type PB[6]) covers and protects only specific parts of the body eg. coats, aprons, sleeves etc.


ATEX Directive
The ATEX Directive defines what equipment is permitted in an environment where an explosive atmosphere may exist. Portwest recommend using garments certified to EN1149 and EN ISO 11611 for added protection in an ATEX environment.
