EN 467:1995 – PROTECTIVE CLOTHING – PROTECTION AGAINST LIQUID CHEMICALS – PERFORMANCE REQUIREMENTS FOR PROTECTIVE CLOTHING
(EN 14605:2005 supersedes EN 467:1995)
This standard specifies the minimum requirements for clothing (e.g. aprons, sleeves, and hoods) that provides protection for the wearer against liquid chemicals and the performance requirements for the material used to manufacture chemical protective clothing. Since garments made in compliance with these requirements and those specified in EN 340 and EN 467 may be worn with garments that do not comply with these standards, this standard does not outline requirements for outfits comprised solely of chemical protective clothing.
If risks to the wearer are associated with occasional splashes from corrosive and non-volatile chemicals, type 3 chemical protective clothing is sufficient when worn in combination with protective boots, gloves, and a visor. This apparel and protective equipment provide sufficient protection against commonly encountered acids and alkalis.
Manufacturing and expiration dates (formatted as “month and year”) must be added to the clothing’s labels. In addition to the pictogram that denotes the clothing’s resistance to chemicals, the following capacities may be specified (note: a higher number indicates better performance):
- abrasion resistance class (1 to 6)
- resistance to heat blocking class (1 or 2)
- flex cracking resistance class (1 to 5)
- puncture resistance class (1 to 5)
- tear resistance class (1 to 5)
- coating adhesion strength class (1 to 5)
- resistance to permeation by liquids class (1 to 6)
- seam strength class (1 to 5)
