Asuperscript epsilon (e) 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 significant num

3、ber 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 chemical proce

4、ss 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, and fit.Some of t

5、hese 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 F23s standards re

6、quires 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 potential hazard and

7、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 safety and health of

8、 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 ChemicalResistance, Mate

9、rial 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 appropriate clo

10、thing. 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 of the other, wi

11、thoutcombining 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 regulatorylimitations prior

Evaluation of Material Chemical Resistance5.1 Applicable Standards:5.1.1 Test Method F 739 (Resistance of Protective ClothingMaterials to Permeation by Liquids or Gases Under Condi-tions of Continuous Contact)The resistance of a protectiveclothing material to permeation by a test chemical is

41、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 separates the test chemical fromthe collection me

42、dium. 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 F 739 permits several configurations ofthe test, including the choice of coll

43、ection media, detectionsystems, the test temperature, and length of the test.5.1.2 Test Method F 1383 (Resistance of Protective Cloth-ing Materials to Permeation by Liquids or Gases UnderConditions of Intermittent Contact)This test method is avariation of Test Method F 739 and is used to measurebrea

44、kthrough detection time and permeation rate throughspecimens of protective clothing under the conditions ofintermittent contact of the test chemical with the specimen.5.1.2.1 Test Method F 1383 is designed to simulate the typeof chemical exposures where chemical contact occurs throughperiodic exposu

45、re or through repeated splashes depending onthe type of task in which the clothing wearer is involved.5.1.2.2 Test Method F 1383 permits several options forspecifying the frequency and length of chemical contact withthe material specimens. Because chemical contact with thespecimen is varied, the tes

46、t method specifies the reporting ofcumulative permeation as opposed to permeation rate. One ofthe options for using Test Method F 1383 is to measure thelength of time for a specific chemical to permeate through acandidate clothing material after a single “splash” exposurefollowed by a saturated vapo

47、r exposure. This test protocol cansimulate how clothing is exposed during actual use.5.1.3 Test Method F 1407 (Resistance of Chemical Protec-tive Clothing Materials to Liquid PermeationPermeationCup Method)In this test method, permeation of chemicalsthrough a clothing specimen is measured gravimetri

48、cally. 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 calculated and the breakthrough time est

49、i-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 F 1407 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 mixture.5.1.4 Test Method F 903 (Resistance of M
