本推荐规程涵盖水下化学注入输送系统（不包括修井和地下设备）的设计、规范、测试、鉴定、安装、调试和操作。它涵盖了从位于主设施（陆上或海上）上的化学品储罐到水下注入点的水下化学品注入输送系统。它讨论了平台上部、水下和地下范围之间的接口，以及工程、机械设备和控制之间的接口。

This recommended practice covers the design, specification, testing, qualification, installation, commissioning, and operation of subsea chemical injection delivery systems (excluding workover and subsurface equipment). It covers subsea chemical injection delivery systems from the chemical storage tank located on a host facility (onshore or offshore) to injection points subsea with a holistic approach. It discusses interfaces between topsides, subsea, and subsurface scopes, as well as between engineering, mechanical equipment, and controls.
