2、supersedes BS EN 374-3:2003 which is withdrawn.BSI, as a member of CEN, is obliged to publish EN 16523-1:2015 as aBritish Standard. However, attention is drawn to the fact that duringthe development of this European Standard, the UK committee votedagainst its approval as a European Standard.The foll

3、owing opinions regarding this standard and EN 16523-2 havebeen expressed by the UK committee: EN 16523-1 and EN 16523-2 were drafted with the intention ofhaving one test method that can be applied to gloves, footwear andclothing. However, as written, these standards do not align withclause 4.3, Perm

4、eation test, from the chemical-protective footwearstandard, EN 13832-1:2006. The dimensions outlined for the design of the permeation cells inclause 6.1 are unnecessarily restrictive. The inter-laboratory trialinadvertently showed that the size of the test cell does not have asignificant effect on t

5、he result while benefits can be gained by usingdifferent sized cells for closed loop and open loop testing, includingmaximized sensitivity and minimized uncertainty of measurement. The test methods described in EN 16523-1 and EN 16523-2 do notconsider cumulative permeation. It is increasingly recogn

6、ized thatbreakthrough time alone is a poor indicator of chemical protection,especially when considering the latest generation of barrier-laminatematerials.

NOTE CEN/TC 162 WG 13 has foreseen to work on other test methods in the future that will spread in several standard parts: Permeation by solid chemical under conditions of continuous contact; Permeation by chemical under conditions of intermittent contact; Permeation by

BS EN 16523-1:2015EN 16523-1:2015 (E) 5 Introduction Users involved in the production, use, transportation, and emergency response with liquid chemicals can be exposed to numerous compounds capable of causing harm upon contact with the human body. The h

39、armful effects of these chemicals can range from acute trauma such as skin irritation and burn to chronic degenerative disease, such as cancer. Since engineering controls may not eliminate all possible exposures, attention is often placed on reducing the potential for direct skin contact through the

40、 use of personal protective equipment (PPE) that resists permeation, penetration and degradation. The test method described in this part of EN 16523 is intended to be used to evaluate the barrier effectiveness of materials used for protective clothing, gloves and footwear materials against permeatio

41、n by liquid chemicals. This method does not assess the chemical degradation or penetration of the material. Resistance to penetration by liquid chemicals can be determined by using for example ISO 6530 10 while resistance to penetration by liquid chemicals under pressure can be determined by using f

42、or example ISO 13994 11. Resistance to chemical degradation can be determined by EN 374-4 2 for gloves and EN 13832-1:2006, 4.2 3 for footwear. This method provides tests results in terms of breakthrough time. This parameter is a key measure of the effectiveness of a material to act as a barrier to

43、the challenge chemical. Such information is used in the comparison of the performances of PPE materials during the process of selecting PPE for protection from hazardous chemicals. Long breakthrough times are characteristic of high permeation resistance. Breakthrough time does not provide a correlat

44、ion between protection and the toxicity of the chemicals tested, only cumulative permeation can provide this information. It has been assumed in the drafting of this part of EN 16523 that the execution of its provisions will be entrusted to appropriately qualified and experienced people with a sound

45、 understanding of analytical chemistry. Appropriate precautions should be taken when carrying out this type of testing in order to avoid injury to health and contamination of the environment. A future part of EN 16523 will explain the use of the series of standards EN 16523. EN 16523-1:2015 (E)BS EN
