防护服. 液体化学剂的防护. 防护服材料对液体农药制剂的排斥、抑制和渗透性测量

[中文适用范围]： 本文件规定了一种测试方法，用于测量已知体积的液体农药施用于防护服材料时的排斥性、保留性和渗透性。 在施用液体农药期间或之后，没有对测试样本施加外部静水压力或机械压力。 污染程度取决于多种因素，例如暴露类型、施用技术和农药配方。 由于暴露水平差异很大，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 ml 液体制剂即可实现低水平污染，使用 0.2 ml 即可实现高水平污染。 该测试方法不测量抗渗透性或抗降解性。 该测试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对挥发性农药制剂的影响。 本文件适用于新材料或经过水洗或模拟磨损等处理的材料的评估。 应报告治疗详情。 该测试方法还可用于确定防护服材料对新农药制剂渗透的抵抗力。 [外文原描述]： 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.
