The work of preparing International Standards is normally ca

12、rried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare Internat

14、ional Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the el

20、User-Sharabianl. ShahramteNot kx Resale. 11Z32013 2259:26 MSTISO 6529:2013(E)IntroductionPeople involved in the production, use, transportation and emergency response with liquid and gaseous chemicals can be exposed to numerous compounds capable of causing harm upon contact with the human body. The

21、deleterious 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 throug

22、h the use of protective clothing that resists permeation, penetration and degradation.The test methods described in this International Standard are intended to be used to evaluate the barrier effectiveness of materials used for protective clothing (see Note) against ingress by liqu:d or gaseous chem

23、icals. Options are provided for conducting this testing under both conditions of continuous or intermittent contact with the chemicals.These test methods provide options for reporting test results in terms Ofbreakthrough time, permeation rate and cumulative permeation. These parameters are key measu

24、res of the effectiveness of a clothing material to act as a barrier to the test chemical. Long breakthrough times, low permeation rates and low cumulative permeation mass are characteristic of high level barrier materials.Resistance to penetration by liquid chemicals should be determined by using IS

25、O 6530 while resistance to penetration by liquid chemicals under pressure should be determined by using ISO 13994. These International Standards are listed in the Bibliography.It has been assumed in the drafting of this International Standard that the execution of its provisions will be entrusted to

26、 appropriately qualified and experienced people with a sound 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.NOTE Finished items of protective clothing includ

27、e gloves, arm shields, aprons, suits, hoods, boots, etc. The phrase specimens from finished items encompasses seamed and other discontinuous regions as well as the usual continuous regions of protective clothing items.公 TCA dCopyright Intemational Organization IOr S11rights reservedVStandar citation

30、1 ScopeThis International Standard describes laboratory test methods to determine the resistance of materials used in protective clothing, including gloves and including footwear, when the footwear is an integral part of the clothing, to permeation by liquid or gaseous chemicals under the conditions

31、 of either continuous or intermittent contact.Method A is applicable to testing against liquid chemicals, either volatile or soluble in water, expected to be in continuous contact with the protective clothing material.Method B is applicable to testing against gaseous chemicals expected to be in cont

32、inuous contact with the protective clothing material.Method C is applicable to testing against gaseous and liquid chemicals, either volatile or soluble in water, expected to be in intermittent Contactwith the protective clothing material.These test methods assess the permeation resistance of the pro

33、tective clothing material under laboratory conditions in terms of breakthrough time, permeation rate and cumulative permeation. Thesetest methods also enable qualitative observations to be made of the effects of the test chemical on the material under test.These test methods are only suitable for me

34、asuring permeation by liquids and gases. Permeation by solid challenge chemicals is beyond the scope of this International Standard.NOTE It can be difficult or impossible to normalize the results of permeation tests carried out against solid challenge chemicals. The normalized rate of permeation is

35、dependent on the area of fabric exposed to the challenge chemical. In the case of solids this will, in turn, depend also on factors such as particle size, size distribution, particle shape and packing considerations.These test methods address only the performance of materials or certain materials* c

36、onstructions (e.g. seams). These test methods do not address the design, overall construction and components, or interfaces of garments, or interfaces between garments and gloves or garments and footwear, or Otherfactors which may affect the overall chemical protection offered by protective clothing

37、, gloves or footwear or combinations of chemical protective clothing, gloves and footwear.It is emphasized that these tests do not necessarily simulate conditions to which materials are likely to be exposed in practice. In most cases the conditions of the permeation test will be far more challenging

38、 than expected workplace conditions.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

40、 apply.3.1analytical techniquemethod of quantifying the amount of permeated chemical in the collection mediumNote 1 to entry: Such methods are often specific to individual chemical and collection-medium combinations.EXAMPLE Applicableanalytical techniques can include Ultraviolet(UV) and infrared (IR

41、) spectrophotometry, mass spectrometry, pH measurement, ion chromatography, conductimetry, CoIourimetry, atmospheric analytical detector tubes and radionuclide tagging/detection counting. Although gas- and liquid-chromatography are separation techniques rather than detection methods they can be used

42、 in conjunction with suitable detectors to quantify the amount of permeated chemical in the collection medium.3.2breakthrough detection timeelapsed time measured from the start of the test to the sampling time that immediately precedes the sampling time at which the test chemical is first detectedKe

43、y1 steady-state permeation (the circles represent actual measured data-points)Y permeation rate (gcm2min) time (min)NOTE 1 The breakthrough detection time is dependent on the sensitivity of the method and the frequency of sampling of the collection medium.NOTE 2 The breakthrough detection time for a

44、 method sensitivity of 0,05 gcm2mn is 23 min but would be reported at 20 min, which corresponds to the last sampling time preceding breakthrough (since interpolation of data is not permitted). The normalized breakthrough detection time at a normalization permeation rate of 0,1 gcm2min is 33 min, but

45、 similarly would be reported at 28 min, which corresponds to the preceding sampling time. The steady-state permeation rate is approximately 0,15 gcm2min.9 ISO 2013 - All rights reservedCopyright International Organization IOr StandarcizdtionProvided by MS under license wh ISCNo reproduction or netw(
