中文名称：防护服 对液体化学品的防护 通过防护服材料测定液体杀虫剂配方的驱避性、滞留性和渗透性

标准范围
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.
