Protective clothing - Protection against liquid chemicals - Performance requirements for chemical protective clothing with liquid-tight connections between different parts of the clothing for emergency teams (Type 3 ET Equipment)

This European Standard specifies the minimum requirements, test methods, marking and information supplied by the manufacturer for the following ventilated and non-ventilated liquid-tight chemical protective suits.
Full body protective clothing with liquid-tight connections between different parts of the clothing (Type 3 liquid-tight clothing) and, with liquid-tight connections to component parts, 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, with or without hood or visor, with or without boot-socks or over-boots, with gloves attached liquid tight to the suit.
It describes personal protective ensembles for use by emergency teams, e.g. first responders or fire brigades, in situations where the chemical hazards are known. Type 3- ET suits are generally used during rescue operations, salvage work, cleanup and decontamination procedures, especially to protect against liquid and solid chemicals. Chemical protective clothing conforming to this standard is not designed to provide protection against gases and vapours, nor substances with a high vapour pressure.
Suits described in this standard have to completely cover the body. It is designed with liquid tight connections to suit socks, or booties and liquid tight gloves. They are not designed as respiratory protection, but they need to provide adequate liquid protection (Jet test) where joints to respiratory devices are required. Minimum performance classes for mechanical properties are defined.
This standard specifies special performance requirements for both the materials of construction of the chemi-cal protective suit and for the suit as a whole, including component parts, such as respiratory protective de-vices, gloves, boots, seams, joins and assemblages. This standard does not establish minimum criteria for protection for non-chemical hazards, e.g. radiological, fire, heat, explosives etc. This type of equipment is not intended for total immersion in liquids. Chemical protective clothing conforming to this standard is not designed to provide protection against gases and vapours.
The basic performance criteria for the component parts: gloves, boots or respiratory protective equipment are given in other European Standards, (these Type 3-ET garments need to fulfil the requirements of the related product standards for gloves or boots etc, and the minimum requirements defined in this Standard). The chemical protection suits specified in this standard are designed to be used with respiratory protective devices.

1 Scope
This European Standard specifies the minimum requirements, test methods, marking and information supplied
by the manufacturer for the following ventilated and non-ventilated liquid-tight chemical protective suits.
Full body protective clothing with liquid-tight connections between different parts of the clothing (Type 3 liquid-
tight clothing) and, with liquid-tight connections to component parts, gloves, boots, visors or respiratory protec-
tive equipment, which may be specified in other European Standards. Examples of such clothing are one-
piece coveralls or two piece suits, with or without hood or visor, with or without boot-socks or over-boots, with
gloves attached liquid tight to the suit.
It describes personal protective ensembles for use by emergency teams, e.g. first responders or fire brigades,
in situations where the chemical hazards are known. Type 3- ET suits are generally used during rescue opera-
tions, salvage work, cleanup and decontamination procedures, especially to protect against liquid and solid
chemicals. Chemical protective clothing conforming to this standard is not designed to provide protection
against gases and vapours, nor substances with a high vapour pressure.
Suits described in this standard have to completely cover the body. It is designed with liquid tight connections
to suit socks, or booties and liquid tight gloves. They are not designed as respiratory protection, but they need
to provide adequate liquid protection (Jet test) where joints to respiratory devices are required. Minimum per-
formance classes for mechanical properties are defined.
This standard specifies special performance requirements for both the materials of construction of the chemi-
cal protective suit and for the suit as a whole, including component parts, such as respiratory protective de-
vices, gloves, boots, seams, joins and assemblages. This standard does not establish minimum criteria for
protection for non-chemical hazards, e.g. radiological, fire, heat, explosives etc. This type of equipment is not
intended for total immersion in liquids. Chemical protective clothing conforming to this standard is not de-
signed to provide protection against gases and vapours.
The basic performance criteria for the component parts: gloves, boots or respiratory protective equipment are
given in other European Standards, (these Type 3-ET garments need to fulfil the requirements of the related
product standards for gloves or boots etc, and the minimum requirements defined in this Standard). The
chemical protection suits specified in this standard are designed to be used with respiratory protective de-
vices.

4.3 Strength of detachable joins
The strength of detachable joins between the suit and detachable parts e.g., between gloves (chemical resis-
tant) and sleeves, boots and trouser legs, and bonded in facemasks, shall not be less than 100 N when tested
in accordance with 6.4.
If additional, separate outer gloves are used to fulfil additional mechanical and thermal requirements the pull
force of the outer gloves shall be more than 30 N.
4.4 Chemical permeation
Chemical protective clothing materials of construction (garment, bootees, boots, gloves, visor, if fitted) shall
fulfil liquid permeation requirements given in Table 3.
If the manufacturer claims a suit is reusable after cleaning and disinfection (not decontamination), the suits
shall be treated as described in clause 4.1 of this standard.
If the type 3-ET suit only achieves class 2 or lower after testing with a chemical in accordance with this stan-
dard the chemical protective suit may be unsuitable for use with this chemical under continuous exposure.
NOTE 1 The list of permeation test chemicals specified in Table 2 is not inclusive of all the chemicals for which the type
3-ET suit may be used.
NOTE 2 The standard test chemicals in Table 4 are representative of a number of different groups or classes of chemi-
cals regardless of their physical state (i.e. their generic representation
NOTE 3 Despite obtaining favourable permeation performance results, exposure of the type 3-ET suit material to a
given chemical or chemicals can result in significant chemical permeation into that material. After operational use, the user
should ascertain whether permeation has occurred and, if so, whether such permeation either presents a hazard to sub-
sequent wearers or compromises the future level of protection afforded by the material.
The permeation performance requirements in table 3 shall be fulfilled when tested with the battery of chemi-
cals listed in table 4. Additional chemicals may be tested if the manufacturer wishes to claim additional suit
performance beyond the minimum performance requirements specified by this standard. If claiming these
additional chemicals in the user instructions, the manufacturer shall provide the corresponding test reports.
The fabric, seams and all suit components shall be tested against the same chemicals. The manufacturer
shall select at least 5 chemicals from Table 4, these 5 chemicals shall be used for all testing.
