1 Scope
This European Standard specifies the minimum requirements, test methods, marking and information
supplied by the manufacturer for ventilated and non-ventilated gas-tight chemical protective suits.
It specifies full body personal protective ensembles to be worn for protection against solid, liquid and
gaseous chemicals, including liquid and solid aerosols.
!This standard does not establish minimum criteria for protection for non-chemical hazards, e.g.
radiological, fire, heat, explosive hazards, infective agents." This type of equipment is not intended for
total immersion in liquids.
!The seams, joins and assemblages attaching the accessories are included within the scope of this
standard. The basic performance criteria for the components such as gloves, boots or respiratory
protective equipment are given in other Standards, supplemantary requirements are provided in this
standard."
Particulate protection is limited to physical penetration of the particulates only.
!Chemicals such as violently air sensitive reagents, unstable explosives and cryogenic liquids have
not been considered since protection against these additional hazards is beyond the scope of this
standard."

3 Terms and definitions
For the purposes of this document, the terms and definitions given in CEN ISO/TR 11610 and EN 132
together with the following apply.
3.1
assemblage
permanent fastening between two or more different garments, or between the protective clothing and
accessories obtained for example by sewing, welding, vulcanizing, gluing
[SOURCE: EN 1073-1:1998]
3.2
join
non-permanent fastening between two different garments, or between protective clothing and
accessories
3.3
bootees
sock like gastight extension of the suit leg that encapsulates the entire foot
Note 1 to entry: Intended to be worn inside separate (i.e. not attached) protective boots or protective shoes.
3.4
cleaning
removal of contamination or soiling
Note 1 to entry: There are several separate types of cleaning that may be applicable to chemical protective
clothing. The purpose of each type of cleaning is distinct, though the same operation may, under some
circumstances, fulfil the requirements of more than one type of cleaning.
3.4.1
hygienic cleaning
operation to remove soiling that originates from the body of the wearer of the suit
Note 1 to entry: The purpose of this type of cleaning is to render the inside of the suit sufficiently clean that
another wearer can then safely and comfortably wear it. Hygienic cleaning can consist of rinsing or wiping the
inside of the suit with a disinfectant solution.
Note 2 to entry: An example of soiling intended to be removed by hygienic cleaning is perspiration.

EN 943-1:2015+A1:2019 (E)
3.4.2
washing
operation to remove general soiling that does not originate from either the wearer of the suit or the
chemical hazards against which the suit is worn as protection
Note 1 to entry: An example of soiling intended to be removed by washing is mud.
3.4.3
decontamination
operation to remove chemical contamination from the outside of the suit
Note 1 to entry: The primary purpose of decontamination is to render the outside of the suit sufficiently clean
that the wearer can remove the suit without coming into contact with those chemicals from which the suit has
been protecting him or her. A secondary aim of decontamination may be to render the suit sufficiently chemically
clean that it will not contaminate future wearers or personnel involved in the maintenance and/or storage of the
suit before it is next used. Decontamination may involve wiping or rinsing the suit with copious amount of water,
or treatment with a solution, liquid or solid in order to neutralize the contamination or otherwise render it
harmless.
3.5
disinfection
purposeful reduction of the number of certain unwanted microorganisms by physical or chemical
inactivation, so that they can cause no more infection under the given circumstances
3.6
external ventilating hose
hose that is used to supply a type 1 suit with breathable air providing internal ventilation
3.7
integral overshoe
gas-tight integrated footwear, connected to the chemical protective suit and intended to be worn with
personal footwear inside thus protecting the wearer’s feet and footwear
Note 1 to entry: The integral overshoe and the personal footwear together fulfil the requirements of footwear.
An overshoe may have either a permanent or detachable outsole.
3.8
!gas-tight chemical protective suit
one-piece garment with hood, gloves and boots which, when worn with appropriate respiratory
protective devices, provides the wearer a high degree of protection against harmful liquids, particles
and gaseous or vapour-phase contaminants"
3.8.1
Type 1a - gas-tight chemical protective suit
(type 1a suit)
gas-tight chemical protective suit to be used in conjunction with a breathable air supply which is both

Note 1 to entry: e.g. a self-contained open-circuit compressed-air breathing apparatus.
3.8.2
Type 1b - gas-tight chemical protective suit
(type 1b suit)
gas-tight chemical protective suit to be used in conjunction with a breathable air supply independent of
the ambient atmosphere supplied from or worn outside the suit

EN 943-1:2015+A1:2019 (E)
Note 1 to entry: e.g. a self-contained open circuit compressed air breathing apparatus.
Note 2 to entry: As chemical protective suits are used with respiratory devices, special attention should be
given to the adequate selection and fit of respiratory protective equipment. The limiting factors for the use of
respirators should be taken into consideration.
3.8.3
Type 1c - gas-tight chemical protective suit
(type 1c suit)
gas-tight chemical protective suit to be used in conjunction with breathable air providing positive
pressure where the suit is the face piece
Note 1 to entry: e.g. air lines where the wearer breathes from the suit.
3.8.4

4 Performance requirements
4.1 General
This European Standard requires that various materials of construction and components of the suit be
tested for resistance to chemical permeation. In cases where more than one chemical is tested, each
component and material of construction shall be tested against each chemical.
!Pre-conditioning and conditioning shall be carried out in accordance with EN 14325:2018, 4.2 and
4.3 for those mater
