A collaborative approach, involving resources and expertise from several countries, was used to develop a test cell to measure cumulative permeation by a solid-state collection technique. The new technique was developed to measure the permeation of pesticide active ingredients and other chemicals with low vapor pressure that would otherwise be difficult to test via standard techniques. The development process is described and the results from the final chosen test method are reported. Inter-laboratory studies were conducted to further refine the new method and determine repeatability and reliability. The revised test method has been approved as a new ISO/EN standard to measure permeation of chemicals with low vapor pressure and/or solubility in water.
采用一种协作方法，整合了来自多个国家的资源和专业知识，开发了一个测试单元，用于通过固态收集技术测量累积渗透率。开发这项新技术是为了测量农药活性成分和其他蒸气压低的化学品的渗透率，否则通过标准技术很难进行测试。描述了开发过程，并报告了最终选定测试方法的结果。进行了实验室间研究，以进一步完善新方法并确定其重复性和可靠性。修订后的测试方法已被批准为一项新的ISO/EN标准，用于测量蒸气压低和/或在水中溶解度低的化学品的渗透率。
