1、Designation: F1296 08 (Reapproved 2015)Standard Guide forEvaluating Chemical Protective Clothing1This standard is issued under the fixed designation F1296; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision.

2、A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONASTM Committee F23 was established in 1976 for the purpose of producing standards for use inthe evaluation of protective clothing. A

3、significant number of these standards have applied toprotection against chemicals. Chemical protective clothing ranges from aprons and gloves to totallyencapsulating ensembles. Chemical protective clothing is widely used throughout in several differentapplications including the general industry, the

4、 chemical process industry, oil refining, agriculture,hazardous materials remediation, and emergency response.The effective development and selection of chemical protective clothing requires information onseveral aspects of the clothing, including chemical resistance, physical integrity, comfort, an

5、d fit.Some of these characteristics can be evaluated using swatches of the materials from which the clothingis fabricated. Other characteristics require testing of the finished items of clothing. Committee F23 hasdeveloped test methods for both types of evaluations.The successful use of Committee F2

6、3s standards requires an awareness and understanding of eachstandard as well as the interrelationship of the standards.The successful application of chemical protective clothing requires the careful matching of theproper level of protection and performance characteristics of clothing with the potent

7、ial hazard and thefunctional requirements of the tasks to be performed while wearing the clothing.1. Scope1.1 This guide is intended to aid in the application ofstandards for the development, specification, and selection ofchemical protective clothing with the ultimate goal of main-taining the safet

8、y and health of workers who come into contactwith hazardous chemicals.1.2 This guide provides a short description of each refer-enced standard and then makes specific recommendations forthe use of these standards. The referenced standards areorganized under the following headings: Material ChemicalR

9、esistance, Material Physical Properties, Seam and ClosurePerformance, and Overall Clothing Performance.1.3 No protocol can ensure the selection of protectiveclothing that guarantees worker protection. The purpose oftesting is to generate data and information that will allow theselection of the most

10、appropriate clothing. Ultimately, clothingselection is based on technical evaluation of available infor-mation and professional assessment of risk.1.4 The values stated in SI units or in other units shall beregarded separately as standard. The values stated in eachsystem must be used independently o

11、f the other, withoutcombining values in any way.1.5 This standard does not purport to address the safetyconcerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety andhealth practices and determine the applicability of regulatorylim

32、tee F23and other technical committees can be used individually or aspart of an integrated protocol in the development, selection,specification, and use of chemical protective clothing.4.2 The standards are intended as a means by whichinformation can be requested, generated, and reported in aconsiste

Test methods offer procedures forevaluating chemical protective clothing at standardized condi-tions to allow comparison.4.4 The information on clothing performance must be com-bined with profession

34、al judgment, and a clear understanding ofthe clothing application, to provide the best protection to theworker. All chemical protective clothing use must be based ona hazard assessment to determine the risks for exposure tochemicals and other hazards. Conduct hazard assessments inaccordance with 29

38、ticeF2061.4.7 Appendix X1 is an example of how several of thereferenced standards can be combined into a protocol to selectthe most suitable chemical protective clothing for a givenapplication. Briefly, the process is one of defining the require-ments of the application and then (by testing) elimina

39、ting thosecandidates that are unsuitable.4.8 Appendix X2 provides a chart to cross reference U.S.Standards with European and International Standards. Thischart shows only analogous standards for measuring the sameproperty or evaluating the similar chemical protective clothingand does not imply that

40、results from different tests will becomparable.5. Evaluation of Material Chemical Resistance5.1 Applicable Standards:5.1.1 Test Method F739 (Resistance of Protective ClothingMaterials to Permeation by Liquids or Gases Under Condi-tions of Continuous Contact)The resistance of a protectiveclothing mat

41、erial to permeation by a test chemical is assessedby measuring the breakthrough detection time, normalizedbreakthrough detection time, and subsequent permeation ratethrough replicate specimens of the material.5.1.1.1 In the permeation test apparatus, the protectiveclothing material specimens separat

42、es the test chemical fromthe collection medium. The liquid or gas collection medium isanalyzed quantitatively for the challenge chemical concentra-tion that permeates through the test specimen as a function oftime after it contacts the material.5.1.1.2 Test Method F739 permits several configurations

43、 ofthe test, including the choice of collection media, detectionsystems, the test temperature, and length of the test.5.1.2 Test Method F1383 (Resistance of Protective ClothingMaterials to Permeation by Liquids or Gases Under Condi-tions of Intermittent Contact)This test method is a variationof Test

44、 Method F739 and is used to measure breakthroughdetection time and permeation rate through specimens ofprotective clothing under the conditions of intermittent contactof the test chemical with the specimen.5.1.2.1 Test Method F1383 is designed to simulate the typeof chemical exposures where chemical

45、 contact occurs throughperiodic exposure or through repeated splashes depending onthe type of task in which the clothing wearer is involved.5.1.2.2 Test Method F1383 permits several options forspecifying the frequency and length of chemical contact withthe material specimens. Because chemical contac

46、t with thespecimen is varied, the test method specifies the reporting ofcumulative permeation as opposed to permeation rate. One ofthe options for using Test Method F1383 is to measure thelength of time for a specific chemical to permeate through acandidate clothing material after a single “splash”

47、exposurefollowed by a saturated vapor exposure. This test protocol cansimulate how clothing is exposed during actual use.5.1.3 Test Method F1407 (Resistance of Chemical Protec-tive Clothing Materials to Liquid PermeationPermeationCup Method)In this test method, permeation of chemicalsthrough a cloth

48、ing specimen is measured gravimetrically. Thechemical is placed in a shallow cup and the clothing specimenclamped over the top of the cup. The interior surface of theclothing surface is left open to air. The cup assembly isweighed periodically, and from the change in weight, thepermeation rate calcu

49、lated and the breakthrough time esti-mated. The clothing material specimen is also observed forvisible changes in appearance that would indicate chemicaldegradation.5.1.3.1 Physical properties of the clothing specimen can bemeasured before and after the exposure as another means forassessing chemical resistance.5.1.3.2 Test Method F1407 is applicable to chemicals withsufficiently high vapor pressure such that they will readilyevaporate upon permeation through the clothing material. Thetest cannot distinguish the permeation of different chemicalsfrom a chemical mixtur
