1.1 The purpose of this guide is to provide a recommended list of both liquid and gaseous chemicals for evaluating protective clothing materials in testing programs. 1.2 Results derived from testing programs using these lists of challenge chemicals are not intended for the definitive characterization of protective clothing materials. 1.3 This list of challenge chemicals is not inclusive of all chemical challenges; the chemicals were chosen to represent broad ranges of liquid and gaseous chemical classes and properties. Not all chemical classes are represented. Other chemicals, especially those of interest to the manufacturer or user, should be tested in addition to those recommended in this guide. 1.4 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. A specific hazards statement is given in Section 7.
This guide establishes a recommended list of challenge chemicals to encourage those who evaluate chemical protective clothing to test a minimum number of chemicals in common. This list will simplify the comparison of data from different sources. This guide may also serve material developers or evaluators in screening candidate protective clothing materials. Test methods applicable to the use of this guide include, but are not limited to, Test Methods F 903 and F 739. 5.3.1 The battery of chemical gases shall not be used for testing material penetration resistance because Test Method F 903 has been designed for measuring liquid penetration only. 5.3.2 Evaluation of materials against the gaseous chemical battery is primarily intended for those materials used in the construction of totally-encapsulating protective suits or other clothing items that are designed to prevent exposure to chemical vapors or gases. 1.1 The purpose of this guide is to provide a recommended list of both liquid and gaseous chemicals for evaluating protective clothing materials in testing programs. 1.2 Results derived from testing programs using these lists of challenge chemicals are not intended for the definitive characterization of protective clothing materials. 1.3 This list of challenge chemicals is not inclusive of all chemical challenges; the chemicals were chosen to represent broad ranges of liquid and gaseous chemical classes and properties. Not all chemical classes are represented. Other chemicals, especially those of interest to the manufacturer or user, should be tested in addition to those recommended in this guide.This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
