本标准描述了在水处理中用作过滤介质和吸附剂的原始颗粒和挤压活性炭。它涉及颗粒活性炭（GAC）在过滤吸附器中的选择、放置和使用，其中GAC必须作为过滤介质和吸附剂，以及在主要功能为吸附的系统中。本标准可在采购和接收GAC的文件中引用，并可作为测试GAC样品物理性能的指南。本标准的规定适用于引用本文件的情况，且仅适用于供水服务应用中使用的GAC。

This standard describes virgin granular and extruded activated carbons for use as a filter medium and adsorbent in water treatment. It involves the selection, placement, and use of granular activated carbon (GAC) in filter adsorbers where the GAC must function as filter medium and adsorbent, as well as in those systems where the primary function is adsorption.This standard can be referenced in documents for purchasing and receiving GAC and can be used as a guide for testing the physical properties of GAC samples. The stipulations of this standard apply when this document has been referenced and only to GAC used in water supply service applications.
