This document is currently submitted to the CEN Enquiry.
This document will supersede EN 943-2:2002.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document.
Annex B includes significant technical changes between this document and the previous edition of this
European Standard.
EN 943 consists of the following parts:
EN 943-1: Protective clothing against solid, liquid and gaseous chemicals, including liquid and solid
aerosols — Part 1: Performance requirements for ventilated and non-ventilated gas-tight (Type 1) suits
EN 943-2: Protective clothing against solid, liquid and gaseous chemicals, including aerosols — Part 2:

1 Scope
This European Standard specifies the minimum requirements, test methods, marking and information supplied
by the manufacturer, for chemical protective suits for use by emergency teams (ET), including component
parts such as gloves, bootees and boots which may be specified elsewhere.
It describes personal protective ensembles to be worn during hazardous materials activities involving solid,
liquid, gaseous and particulate hazards only.
This standard does not establish minimum criteria for protection for non-chemical hazards, e. g.
radiological, fire, heat, explosive hazards. 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 performance criteria for the accessories, gloves, boots or respiratory protective equipment are given in
other European Standards.
NOTE Gas-tight suit, a one piece garment with hood, gloves and boots which, when worn with self-contained
breathing apparatus provides the wearer a high degree of protection against harmful liquids, particles and gaseous or
vapour contaminants.

3 Terms and definitions
For the purposes of this European Standard, the terms and definitions in CEN ISO/TR 11610, EN 132 and
in EN 943-1 together with the following apply.
3.1
Type 1a-ET
gas-tight chemical protective suit for use by emergency teams with breathable air supply independent of the
ambient atmosphere, e. g. a self contained open-circuit compressed air breathing apparatus, worn inside the
chemical protective suit
3.2
Type 1b-ET
gas-tight chemical protective suit for use by emergency teams with a breathable air supply, e. g. a self
contained open-circuit compressed air breathing apparatus, worn outside the chemical protective suit
3.3
Attachment point
fixing to the outside of the chemical protective suit to enable equipment required to be fitted, e.g. a torch
4 General requirements
The chemical protective suits type 1a-ET and type 1b-ET shall fulfil the requirements of EN 943-1. Beyond
that the additional or restrictive requirements of this European Standard shall be fulfilled. The performance
class requirements given below are the minimum performance requirements.
NOTE As these chemical protective suits are intended for use in emergency situations it is recommended that the
use of a “pass-thru” on type 1a-ET suits is considered, even though this is an optional requirement.

If only Class 2 is achieved for puncture resistance the instructions for use shall identify that the chemical protective
clothing may not be suitable for use where there is a high risk of puncture.

Pressure pot end point test shall be used for abrasion, flex cracking and flame resistance testing.
5.2 Resistance to permeation by chemicals
The chemical protective clothing materials refer to EN 943-1, (seams, safety footwear, bootees, gloves and
visor or face piece) if fitted, shall be tested for resistance to permeation against the following liquid and
gaseous standard test chemicals given in table 2.

Any material, seams or component shall achieve class 2, not more than 3 chemicals of 15 (table 2) shall have
class 1.
If class 2 is not achieved for any material or component part tested, the instructions for use shall identify that
this chemical protective suit is not suitable for use for this chemical under continuous exposure.
Where safety footwear also provides the chemical permeation resistance, the test specimen shall be taken
from the thinnest point of the footwear according EN 15090 above the join to the sole.
NOTE The test chemicals identified above have been selected to represent a range of aggressive chemicals so as to
ensure that chemical protective suit which meets the requirements of this European Standard will offer protection against a
wide range of chemicals (Classes and Properties). However, it should be recognised that this approach only provides
basic guidance against groups represented by these chemicals and that the performance against chemicals other than
those listed can only be determined by individual tests. See Annex A.

5.3 Protective gloves and safety footwear
5.3.1 Protective gloves
Protective gloves shall also meet the requirements of EN 374-1.
NOTE As EN 374-1 has only very limited mechanical and thermal requirements it may be necessary to use an over-
glove e.g. according to EN 659 to provide greater mechanical or thermal protection.
5.3.2 Safetey footwear
Where safety footwear is fitted, it shall also meet the requirements of EN 15090:2012, type 3.
Where safety footwear is not permanently fitted to the chemical protective suit, any external bootee supplied
by the manufacturer shall comply with the requirements of EN 15090:2012, type 3.
NOTE This standard does not require the performance of bootees to match the chemical protective clothing material
and users should be aware that the performance of a bootee may differ from that of the chemical protective clothing
material. Consequently it may be necessary to specify the required levels of performance specifically for the bootees when
procuring chemical protective clothing.
5.4 Visor
The visor shall meet the requirements of EN 943-1:2013, 5.6, as well as the requirements given below.
When tested in accordance with 8.2 the visor shall pass for each chemical listed in 5.2. This test shall only be
carried out with those test chemicals for which the test according to 5.2 has led to any indication of harm to
the visibility.
6 Performance requirements for seams, joins and assemblages
6.1 Resistance to permeation of closures by chemicals
Closures or closure assemblies shall be tested in accordance with 5.2 for each chemical listed in Table 2.
The basic requirement of this clause is for the main closure component (usually a zipper) to be tested for
resistance to permeation. In many cases the closure system includes one
