这些推荐规程的主要目的是为促进LNG燃料系统的安全可靠设计、工程、施工、运行和维护提供基本参考。本文件可能对那些考虑使用液化天然气作为汽车燃料、希望了解这些设施如何工作的人，以及那些在投资此类设施前应考虑的设计和性能因素的信息的人有用。负责许可和检查液化天然气燃料设施的法规执行人员也可能会发现本文件是一份有用的参考文件。本文件提供了有关LNG燃料系统的基本背景信息。本文件本身不会提供成功设计、建造、操作、维修或检查ANNG燃油系统所需的所有信息。这些推荐做法提供了一些基本信息，让仔细的读者能够理解: •用于描述LNG燃料系统的术语各种类型的液化天然气燃料系统规划和设计燃油系统所涉及的概念LNG燃料系统的基本结构正确操作和维护LNG燃料系统所需的基本步骤更多信息请参考。本文件无意认可或推荐特定材料、设备、供应商或制造商。

The primary purpose of these recommendedpractices is to provide a basic reference topromote the safe and reliable design, engineering, construction,operation and maintenance of LNG fuelingsystems. This document may be useful to those consideringusing LNG for vehicle fueling and who want to learnabout how these facilities work, and to those seekinginformation about the design and performance factorsthat should be considered before investing in such a facility.Code enforcement personnel who are charged withpermitting and inspecting LNG fueling facilities also mayfind this document a useful reference.This document provides basic background informationregarding LNG fueling systems. This document by itselfwill NOT provide all of the information required to successfullydesign, build, operate, service or inspect anLNG fueling system. These recommended practices presentbasic information that should allow the careful readerto understand:• the terminology used to describe LNG fueling systems;• the various types of LNG fueling systems;• the concepts involved in planning and designing LNGfueling systems;• the basic construction of an LNG fueling system;• the basic steps required to properly operate and maintainan LNG fueling system;• references for further information.This document is not intended to endorse or recommendparticular materials, equipment, suppliers or manufacturers.
