1、Designation: F 1001 99a (Reapproved 2006)Standard Guide forSelection of Chemicals to Evaluate Protective ClothingMaterials1This standard is issued under the fixed designation F 1001; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision,

2、the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.INTRODUCTIONWorkers involved in the production, use, and transportation of chemicals can be exposed tonumerous compou

3、nds capable of causing harm upon contact with the human body. The deleteriouseffects of these chemicals can range from acute trauma, such as dermatitis or burns, to chronicdegenerative disease, such as cancer or pulmonary fibrosis. Because engineering controls may noteliminate all possible exposures

4、, attention is often given to reducing the potential for direct skincontact through the use of protective clothing that resists degradation, penetration, and permeation.Standard test methods are being established to measure degradation, penetration, and permeationchemical resistance of protective cl

5、othing materials. Chemical resistance information for a number ofchemicals often accompanies many protective clothing articles. However, because there are so manypossible protective clothing and chemical combinations, the number and type of chemicals appearingin chemical resistance tables vary exten

6、sively.This guide establishes a standardized list of chemicals to be used in evaluating protective clothingmaterials. The list of chemicals includes a broad range of representative chemical classes andproperties. This guide is intended to provide a minimum set of chemicals in generating test results

7、 forprotective clothing users and to aid in screening new materials.1. Scope1.1 The purpose of this guide is to provide a recommendedlist of both liquid and gaseous chemicals for evaluatingprotective clothing materials in testing programs.1.2 Results derived from testing programs using these listsof

8、 challenge chemicals are not intended for the definitivecharacterization of protective clothing materials.1.3 This list of challenge chemicals is not inclusive of allchemical challenges; the chemicals were chosen to representbroad ranges of liquid and gaseous chemical classes andproperties. Not all

9、chemical classes are represented. Otherchemicals, especially those of interest to the manufacturer oruser, should be tested in addition to those recommended in thisguide.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility

10、of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.

20、s of protective clothing terms used inthis guide, refer to Terminology F 1494.4. Summary of Guide4.1 In this guide, two lists of challenge chemicals arerecommended to be used in testing programs to evaluatechemical/protective clothing material interactions or compat-ibility. One list includes 15 liq

21、uid chemicals while the other listincludes six gaseous chemicals. Users of this guide mayevaluate protective clothing materials against either list or bothlists in combination.4.2 Types of testing programs are not specified. However,when a protective clothing material is tested in accordance withthi

22、s guide and any appropriate test method, all results anddocumentation required by the test method should be reportedfor each chemical tested.5. Significance and Use5.1 This guide establishes a recommended list of challengechemicals to encourage those who evaluate chemical protectiveclothing to test

23、a minimum number of chemicals in common.This list will simplify the comparison of data from differentsources.5.2 This guide may also serve material developers orevaluators in screening candidate protective clothing materials.5.3 Test methods applicable to the use of this guide include,but are not li
