3 Terms and definitions
For the purposes of this European Standard the terms and definitions given in prEN ISO 11610 together with the
following apply.
3.1
type 1a-ET - “gas-tight” chemical protective suit
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
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
As chemical protection is used with respiratory devices, special attention shall be given to the adequate selection of
respiratory protective equipment. The limiting factors for the use of filters (e.g. oxygen deficiency) shall be taken
into consideration.
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
The chemical protective suits type 1a-ET and type 1b-ET shall fulfil the requirements of prEN 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 1 The mechanical performance requirements for component parts such as gloves, safety footwear etc. are specified in
other relevant EN's.
NOTE 2 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.
5 Performance requirements of chemical protective clothing materials
5.1 General
The chemical protective clothing shall meet the requirements given in Table 1, when tested in preconditioned
condition against the appropriate clause of prEN 943-1.
NOTE Because limited-use protective clothing is not intended to be used repeatedly the performance requirements
required to demonstrate the durability of the protective clothing material are different to those for materials intended for repeated
use. As a consequence, abrasion resistance and flex cracking resistance performance levels are specified differently for limited-
use and re-usable chemical protective clothing materials.
Table 1 — Minimum performance requirements of chemical protective clothing materials
Performance class Performance class
Property Testing reference Limited-use suits Re-usable suits
Abrasion resistance prEN 943-1 Class 4 Class 6
Flex cracking resistance prEN 943-1 Class 1 Class 4
Flex cracking resistance at low prEN 943-1 Class 2 Class 2
temperatures (-30°C)
Trapezoidal tear resistance prEN 943-1 Class 3 Class 3
Tensile Strength prEN 943-1 Class 4 Class 6
Puncture resistance prEN 943-1 Class 2 Class 3
Resistance to flame prEN 943-1 Class 1 Class 3
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.
5.2 Resistance to permeation by chemicals of chemical protective clothing material, safety
footwear, gloves and visor (if fitted)
The chemical protective clothing material, safety footwear, gloves and visor if fitted, shall be tested for resistance to
permeation against the following liquid and gaseous standard test chemicals given in Table 2:
