2、is the UK implementation of EN 943-1:2015. It supersedes BS EN 943-1:2002 which is withdrawn.BSI, as a member of CEN, is obliged to publish EN 943-1:2015 as a British Standard. However, attention is drawn to the fact that during the development of this European Standard, the UK committee voted again
3、st its approval as a European Standard.The following concerns regarding this standard have been expressed by the UK committee: This standard supersedes BS EN 943-1:2002, which specifiesperformance requirements for both Type 1 and Type 2 chemicalprotective clothing. However, EN 943-1:2015 does not in
4、clude anyrequirements for Type 2 clothing. No alternative provision has beenmade for the standardization of Type 2 chemical protective clothing. Conformance with EN 943-1 is a prerequisite of EN 943-2. The revisionof EN 943-2 has not kept pace with that of EN 943-1 with the resultthat the links betw
5、een the old part 2 and the new part 1 are nolonger compliant with one another. This will make it difficult formanufacturers to approve or re-approve EN 943-2:2002 products.However, it is intended for EN 943-2 to be revised in the future andfor the two parts to once again be mutually compatible. EN 9

45、(E) 5 1 Scope This European Standard specifies the minimum requirements, test methods, marking and information supplied by the manufacturer for ventilated and non-ventilated gas-tight chemical protective suits. It specifies full body personal protective ensembles to be worn for protection against so
46、lid, liquid and gaseous chemicals, including liquid and solid aerosols. This standard does not establish minimum criteria for protection for non-chemical hazards, e.g. radiological, fire, heat, explosive, infective agents. This type of equipment is not intended for total immersion in liquids. The se
47、ams, joins and assemblages attaching the accessories are included within the scope of this standard. This standard specifies only supplementary requirements for components. The basic performance criteria for the components gloves, boots or respiratory protective equipment are given in other European
48、 Standards. Particulate protection is limited to physical penetration of the particulates only. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
