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
