prEN 943-2:2012 (E)
Foreword
This document (prEN 943-2:2012) has been prepared by Technical Committee CEN/TC 162 “Protective
clothing including hand and arm protection and lifejackets”, the secretariat of which is held by DIN.
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:
Performance requirements for gas-tight (Type 1) chemical protective suits for emergency teams (ET)
prEN 943-2:2012 (E)
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.
