30、EN 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 harmful effects of these chemicals can range from acute trauma such

31、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 use of personal protective equipment (PPE) that resists permeation

32、, 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 permeation by liquid chemicals. This method does not assess the chemical deg

33、radation 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 for example ISO 13994 11. Resistance to chemical degradation can be

34、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 the challenge chemical. Such information is used in the comparison

35、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 correlation between protection and the toxicity of the chemicals tested, on

36、ly 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 understanding of analytical chemistry. Appropriate precautions sho

37、uld 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. DINEN 16523-1:2015-04EN 16523-1:2015 (E) 6 1 Scope This European Standard specifies a test

38、method for the determination of the resistance of protective clothing, gloves and footwear materials to permeation by potential hazardous liquid chemicals under the condition of continuous contact. This test method is applicable to the assessment of protection against liquid chemicals that can be co

39、llected only by liquid or gaseous collecting media. This test method is not adapted for the assessment of chemical mixtures, except for aqueous solutions. This standard is used with the specifications given in the products standards (for example EN 374-1 for gloves) where the following information i

40、s defined: any pre-conditioning; precise sampling (place, size, number); associated levels of performance. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the editio

41、n cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 374-1, Protective gloves against chemicals and micro-organisms - Part 1: Terminology and performance requirements 3 Terms and definitions For the purposes of this document, t

42、he following terms and definitions apply. 3.1 analytical technique method of identifying and quantifying the amount of permeated chemical in the collection medium Note 1 to entry: Such methods are often specific to individual chemical and collection-medium combinations. EXAMPLE Applicable analytical

43、 techniques can include ultraviolet (UV) or infrared (IR) spectrophotometry, mass spectrometry, pH measurement, ion chromatography, conductimetry, colourimetry, atmospheric analytical detector tubes and radionuclide tagging/detection counting. Although liquid and/or gas chromatography are separation

44、 techniques rather than detection methods they can be used in conjunction with suitable detectors to quantify the amount of permeated chemical in the collection medium (see Annex C). 3.2 liquid challenge chemical liquid chemical that is used to challenge the protective clothing, gloves and footwear

45、material specimen 3.3 collecting medium liquid or gas on the inner “clean” side of the test sample in which any permeated chemical is collected 3.4 response time time between the actual arrival of the challenge chemical on the collecting side of the specimen and the time when the analytical instrume

46、ntation responds to it DIN EN 16523-1:2015-04 EN 16523-1:2015 (E) 7 3.5 limit of quantification minimum quantity of a substance which can be measured Note 1 to entry: It is the value where the uncertainty of measurement is equal to 50 % of the determined value. 3.6 loop 3.6.1 closed loop system in w

47、hich the collecting medium is re-circulated or stirred through the sampling compartments of the test cell Note 1 to entry: Closed loop systems are not commonly used with gaseous collection media. 3.6.2 open loop system where the collecting medium passes through the sampling compartment of the test c

48、ell without re-circulation Note 1 to entry: Open loop systems may be used with either liquid or gaseous collection media. 3.7 minimum detectable permeation rate MDPR lowest rate of permeation that is measurable with the complete permeation-test system Note 1 to entry: This value is not necessarily the intrinsic limit of detection for the analytical instrument. Note 2 to entry: MDPR is usually based upon 3 times the average background noise. Note 3 to entry: Useful information can be found on the following webs
