ANS 59.52-1998（R2020）规定了柴油发电机润滑油系统的功能、性能和设计要求，柴油发电机为轻水反应堆核电厂提供现场应急电源。本标准涉及与润滑油系统相关的所有机械设备，发动机安装部件除外。这些直接安装在发动机结构本身上的部件不包括在内，但用于定义接口要求的部件除外。本标准还包括润滑油系统仪表和控制功能要求。 它不包括电机、电机控制中心、开关设备、电缆和润滑油系统运行中使用的其他电气设备，但定义接口要求的除外。

ANS 59.52-1998 (R2020) provides functional, performance and design requirements for lubricating oil systems for diesel generators that provide emergency on-site power for light water reactor nuclear power plants. The standard addresses all mechanical equipment associated with the lubricating oil system with the exception of engine-mounted components. These components, which are mounted directly to engine structure itself, are excluded, except to define interface requirements. This standard also includes the lubricating oil system instrumentation and control functional requirements. It excludes motors, motor control centers, switchgear, cables, and other electrical equipment used in the operation of the lubricating oil system, except to define interface requirements.
