本标准旨在制定用于公共饮用水处理和生产的袋式过滤器、筒式过滤器和微滤（MF）或超滤（UF）膜的最低性能要求。本标准旨在描述用于去除微生物污染物的全尺寸UF和MF膜组件、袋式过滤器和筒式过滤器的产品特定挑战性试验（PSCT）的性能评估（PE）试验程序。本标准提供了根据EPA发布在40 CFR第141部分W子部分中的长期2强化地表水处理规则（LT2ESWTR）的要求，制定挑战性测试日志去除值（LRVC-TEST）的程序。

It is the purpose of this Standard to establish minimum performance requirements for bag filters, cartridge filters, and microfiltration (MF) or ultrafiltration (UF) membranes used in the treatment and production of public drinking water.This Standard is designed to describe the performance evaluation (PE) test procedure for the product specific challenge testing (PSCT) of full scale UF and MF membrane modules, bag filters, and cartridge filters for the removal of microbial contaminants. This Standard provides procedures to develop challenge testing log removal values (LRVC-TEST), as required in the EPA's Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR) published in 40 CFR Part 141, Subpart W.
