Diese Europäische Norm legt die Mindestanforderungen, Prüfverfahren, Kennzeichnungen und Informationen des Herstellers für die folgenden belüfteten und nicht belüfteten gasdichten Chemikalienschutzanzüge fest.
Sie beschreibt die persönliche Schutzkleidung, die ausschließlich während des Ansprechens auf gefährliche Stoffe unter Einschluss flüssiger, gasförmiger und partikelförmiger Gefahren zu tragen ist.
Diese Norm gibt keine Minimalkriterien zum Schutz vor nicht-chemischen Gefahren, wie z. B. Radio¬aktivität, Feuer, Hitze, Explosionen, an. Diese Art der Ausrüstung ist nicht für das vollständige Eintauchen in Flüssigkeiten gedacht.
Nähte, Verbindungen und Verbünde zum Anbringen der Zubehörteile werden durch den Anwendungs¬bereich dieser Norm erfasst. Die grundlegenden Leistungskriterien für die Zubehörteile Handschuhe, Schuhe oder Atemschutzgeräte werden durch andere Europäische Normen bereitgestellt.

Vêtements de protection contre les produits chimiques dangereux solides, liquides et gazeux, y compris les aérosols liquids et les particules solides - Partie 1: Exigences de performance pour Type 1 (étanches au gaz) des combinaisons de protection chimique

La présente Norme européenne définit les exigences minimales, les méthodes d’essai, le marquage ainsi que les informations à fournir par le fabricant concernant les combinaisons de protection chimique ventilées et non-ventilées étanches au gaz suivantes.
Elle décrit les combinaisons de protection individuelle devant être portées dans le cadre de réactions dangereuses de matériaux, se présentant uniquement sous forme liquide, gazeuse et de particules.
La présente norme n'établit pas de critères minimum pour la protection contre les dangers non chimiques, par exemple les risques radiologiques, d’incendie, d’explosion ou liés à la chaleur. Ce type d'équipement n'est pas prévu pour une immersion totale dans des liquides.
Les coutures, les jonctions et les assemblages servant à fixer les accessoires sont inclus dans le domaine d'application de la présente norme. Les critères de performance de base pour les accessoires, c'est-à-dire les gants, les bottes ou les équipements de protection respiratoire sont définis dans d'autres Normes européennes.

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, 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.
This standard specifies only supplementary requirements for components. The basic performance criteria for
the components gloves, boots or respiratory protective equipment are given in other European Standards.
Particulate protection is limited to physical penetration of the particulates only.

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.
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.

SIST EN 943-1:2015
EN 943-1:2015 (E)
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
Type 1 - gas-tight chemical protective suit
(type 1 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
independent of the ambient atmosphere and worn inside the suit
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
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.

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.
4.2 Materials
Chemical protective clothing materials of construction (i.e. materials used in the construction of the garment,
bootees, boots, gloves, and (if fitted) visor) shall fulfil all the non-optional test requirements given in Table 1.
The optional tests listed in Table 1 may be carried out at the discretion of the manufacturer in accordance with
intended use. Components such as integral overshoes or boots, integral gloves shall also fulfil the minimum
performance requirements of the respective product standard.
Pre-conditioning and conditioning shall be carried out in accordance with EN 14325:2004, 4.2 and 4.3.
Materials of construction shall comply with all subsections of EN ISO 13688:2013, 4.2.
