ASTMF903–03防护服用材料耐液体渗透性的试验方法

Designation: F 903 – 03Standard Test Method forResistance of Materials Used in Protective Clothing toPenetration by Liquids 1This standard is issued under the fixed designationF 903; the number immediatelyfollowing the designationindicates the year oforiginal adoption or, in the case of revision, 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 liquid chemicals can be exposed tonumerous compounds capable of causing harm upon contact with the human body. The deleteriouseffects of these chemicals can range from acute trauma such as skin irritation and burn to chronicdegenerative disease, such as cancer. Since engineering controls may not eliminate all possibleexposures, attention is often placed on reducing the potential for direct skin contact through the useof protective clothing that resists permeation, penetration, and degradation.This test method determines resistance to penetration only. Resistance to permeation anddegradation should be determined by other test methods.1. Scope1.1 This test method is used to test specimens of protectiveclothing and candidate materials and constructions to be usedin protective clothing. The resistance to visible penetration ofthe test liquid is determined with the liquid in continuouscontact with the normally outside surface of the test specimen.1.2 In some cases, significant amounts of hazardous mate-rials will permeate specimens that pass the penetration tests.For more sensitive analysis use Test Method F 739 to deter-mine permeation.1.3 This test method is not applicable to fi...
