Sioen Professional Protective Clothing - 2016

CHEMICAL
Protection against the risks
caused by handling of chemicals
When handling dangerous chemicals in industry
the risk of an accidental exposure to the hazards
of these chemicals cannot be excluded. Sioen has
developed a range of fabrics that offer a high level
of protection against those chemicals according to
different standards.
EN 14605: Protective clothing against liquid
chemicals (including permeation resistance test)
EN 14605
Type X
This standard specifies the minimum
requirements for the following types of
chemical protective clothing:
• Full-body protective clothing with spraytight
connections between different
parts of the clothing (Type 4: spraytight
clothing) and, if applicable, spraytight
connections to component parts,
such as hoods, gloves, boots, visors or
respiratory protective equipment, which
may be specified in other European
Standards. Examples of such clothing are
one-piece coveralls or two-piece suits.
• Full-body protective clothing with liquidtight
connections between different
parts of the clothing (Type 3: liquid-tight
clothing) and, if applicable, with liquidtight
connections to component parts,
such as hoods, gloves, boots, visors or
respiratory protective equipment, which
may be specified in other European
Standards.
Examples of such clothing are one-piece
coveralls or two-piece suits.
• Partial body protection garments
offering protection to specific parts of
the body against permeation of chemical
liquids. (Type PB (4) or PB (3))
Examples of such garments are e.g.
laboratory coats, jackets, trousers, aprons,
sleeves, hoods etc.
As partial body protection leaves some parts
of the body unprotected this document
specifies only the performance requirements
for the clothing material and the seams.
Note: Partial body chemical protective
garments which offer only protection against
penetration of a small amount of low risk
chemical liquids are within the scope of
EN 13034 (Type PB [6] clothing).
Chemical protective clothing materials
are tested according to the test methods
specified in EN 14325. Performance levels are
to be obtained for all of the following:
• Resistance to permeation of liquids:
permeation is the process whereby a
chemical product slowly moves through
the protective layers on a molecular
level.
• Resistance to penetration by liquids
• Minimum mechanical requirements:
resistance to abrasion, flex cracking (at
normal and at low temperatures), tear
resistance, tensile strength, puncture or
perforation resistance, resistance
to ignition
• Requirements for seams, joints
and assemblages
Crumple flex test Puncture test Trapezoidal tear resistance test Abrasion resistance test
