3、d application ofliquid pesticides can be affected by dermal exposure to liquid pesticide formulations.Use of protectiveclothing can assist in minimizing the danger of contact with potentially harmful pesticides.Nonporousmaterials that provide excellent protection to the user are usually not suitable
4、 for many agriculturalenvironments in which there is a potential for heat stress.Therefore,garments made of porousmaterials that can provide a balance between risk from pesticide exposure and user comfort can alsobe used as personal protective equipment(PPE)for agricultural workers.The movement of l
5、iquidpesticides through these materials is primarily a result of penetration through spaces between fibersand interstices between yarns.As these materials provide protection either by repelling or retainingliquid pesticide,the measurement of these properties is also important.This test method is use
6、d tomeasure repellency,retention,and penetration of liquid pesticides through protective clothingmaterials.The degree of contamination depends on numerous factors such as type of exposure,applicationtechnique,and pesticide formulation.Worker exposure to liquid pesticides can range from lowexposure c
7、aused by spray drift to high exposure as in the case of an accidental spill while mixing orhandling of concentrates.As the level of exposure can vary considerably,this test method is designedto rate relative performance of PPE materials at two levels of contamination.1.Scope1.1 This test method meas
8、ures repellency,retention andpenetration of a known volume of liquid pesticide whenapplied to protective clothing material.No external hydrostaticor mechanical pressure is applied to the test specimen during orafter the application of the liquid pesticide.1.2 This test method is designed to measure
9、performance ofprotective clothing materials at two levels of contamination.Low level of contamination is achieved by applying 0.1-mLliquid formulation and high level by applying 0.2 mL.1.3 This test method does not measure resistance to perme-ation or degradation.1.4 This test method is suitable for
10、 field strength pesticideformulations.This test method may not be suitable for testingprotective clothing materials against volatile pesticides.1.5 The values stated in SI units are to be regarded as thestandard.1.6 This standard does not purport to address all of thesafety concerns,if any,associate
11、d with its use.It is theresponsibility 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.2.Referenced Documents2.1 ASTM Standards:2D123 Terminology Relating to Textiles1This test method is under
