BS EN 943-1:2002 Protective clothing against liquid and gaseous chemicals, aerosols and solid particles. Performance requirements for ventilated and non-ventilated "gas-tight" (Type 1) and "non-gas-tight" (Type 2) chemical protective suits
This European Standard specifies the minimum requirements, test methods, marking and information supplied by the manufacturer for the following ventilated and non-ventilated limited use and re-usable chemical protective suits, including component parts such as gloves and boots which can be specified elsewhere.
Type 1 - "gas-tight" chemical protective suit
Type 1a - "gas-tight" chemical protective suit with a 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.
Type 1b - "gas-tight" chemical protective suit with a breathable air supply, e.g. a self-contained opencircuit compressed air breathing apparatus, worn outside the chemical protective suit.
NOTE As chemical protective suits are used with respiratory devices, special attention should be given to the
adequate selection of respiratory protective equipment. The limiting factors for the use of respirator filters (e.g. oxygen deficiency) should be taken into consideration.
Type 1c - "gas-tight" chemical protective suit with breathable air providing positive pressure, e.g. air lines.
Type 2 -”non-gas tight” chemical protective suit "Non-gas-tight" chemical protective suit with breathable air providing positive pressure.
Specifications for total inward leakage test see annex A.
Specifications for test methods and performance classification for materials, seams, joins and assemblages see annex B.
Specifications for glass paper and glass cloth see annex C.
