BS EN 14325:2018EN 14325:2018 (E) 5 1 Scope This European Standard specifies the performance classification and test methods for materials used in chemical protective clothing, including gloves and footwear. The gloves and boots should have the same c

35、hemical protective barrier requirements as the fabric when an integral part of the clothing. This is a reference standard to which chemical protective clothing performance standards may refer in whole or in part, but this standard is not exhaustive in the sense that product standards may well requir

36、e testing according to test method standards which are not included in this standard. While these performance levels are intended to relate to the usage to which the chemical protective clothing is to be put, it is essential that the chemical protective clothing manufacturer or supplier indicate the

37、 intended use of the protective clothing and that the user (specifier) carries out a risk assessment in order to establish the correct performance level for the intended task. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are ind
