标准范围
本文件规定了一种测试方法，用于测量已知体积的液体杀虫剂在防护服材料上的驱避性、滞留性和渗透性。在施用液体农药期间或之后，不得向试样施加外部静水压或机械压力。污染程度取决于多种因素，如接触类型、施用技术和农药配方。由于暴露水平可能会有很大差异，该方法旨在评估个人防护装备（PPE）材料在两种污染水平下的相对性能。使用0.1毫升的液体配方可达到低污染水平，使用0.2毫升的液体配方可达到高污染水平。本试验方法不测量抗渗透性或抗降解性。本试验方法适用于场强和浓缩农药制剂。该方法可能不适用于测试防护服材料的挥发性农药制剂。本文件适用于评估新材料或经过清洗或模拟磨损等处理的材料。应报告治疗的细节。本试验方法也可用于测定防护服材料对新农药制剂渗透的抵抗力。
This document specifies a test method to measure the repellency, retention and penetration of a known volume of liquid pesticide when applied to a protective clothing material. No external hydrostatic or mechanical pressure is applied to the test specimen during or after the application of the liquid pesticide.
The degree of contamination depends on numerous factors such as the type of exposure, application technique, and pesticide formulation. As the level of exposure can vary considerably, this method is designed to rate the relative performance of personal protective equipment (PPE) materials at two levels of contamination. Low level of contamination is achieved by applying 0,1 ml of liquid formulation and high level by applying 0,2 ml.
This test method does not measure the resistance to permeation or degradation.
This test method is suitable for field strength and concentrated pesticide formulations. This method may not be suitable for testing protective clothing materials against volatile pesticide formulations.
This document is applicable to the evaluation of materials that are new or those that have undergone treatment such as laundering or simulated abrasion. Details of the treatment shall be reported. This test method can also be used to determine the resistance provided by protective clothing materials against penetration of new pesticide formulations.
