通过形态测量聚合物材料的液体渗透测试方法

[中文适用范围]： 本文件中描述的测试方法涵盖了一种确定程序，即确定渗透穿过塑料材料片材、薄膜或板的每种不同燃料成分的量。片材的一侧旨在与液体测试燃料或饱和测试燃料蒸气接触，另一侧旨在暴露于无燃料的环境。测试燃料可以是少量（通常小于十种）碳氢化合物、酒精和任一成分的混合物，也可以是真实汽车燃料的样品，例如可能包含数百种不同成分的燃料。此外，附录 A 还包含对成品燃油系统组件（例如燃油管路、燃油加注管、燃油发送器单元、连接器和阀门）蒸发排放的指导原则。 [外文原描述]： This test method described in this document covers a procedure to speciate that is, to determine the amounts of each different fuel constituent that permeates across sheets, films or slabs of plastic materials. One side of the sheet is meant to be in contact with either a liquid test fuel or a saturated test fuel vapor, the other side is meant to be exposed to an environment free of fuel. The test fuel can either be a mixture of a small (usually smaller than ten) number of hydrocarbon, alcohol and ether constituents or it can be a sample of a real automotive fuel, e.g., one that may contain hundreds of different constituents.Furthermore, Appendix A contains guidelines to speciate evaporative emissions from finished fuel system components such as fuel lines, fuel filler pipes, fuel sender units, connectors and valves.Cross Reference: 1999-01-0376,1999-01-0377,1999-01-0380,2001-01-1999,2002-01-0635,981360,981376,ASTMD5134,ASTME96,J1527_201102,J1527_202201,J1681_202305,J1737_201305,J1737_201908,J2260,J30_201202,J30_202205
