1.1本规程涵盖含光缆的天然气配气和服务管道的操作和维护以及光纤系统的操作和维护。 1.2本规程适用于用于运输天然气的配电和服务线路。 1.3本规程不适用于天然气输送线路。 1.4以英寸-磅为单位的数值应视为标准值。本标准不包括其他计量单位。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 本规程旨在帮助光缆所有者和管道运营商制定将天然气管道作为光缆导管二次使用的操作和维护程序及规程。 必须记住，天然气管道的主要用途是输送天然气，系统的任何二次使用不得对主要功能产生重大影响。光缆所有者和管道运营商有责任决定如何最好地整合管道、光纤系统和光缆的操作和维护程序，以确保安全不受损害，以最佳方式为客户服务，并将增量成本降至最低。 由于为电信目的整合天然气管道设施和光纤的做法是一项新兴活动，本标准将有助于为其快速安全部署制定指导方针，并将确保所安装的设施能够长期运行。

1.1 This practice covers the operation and maintenance of natural gas distribution and service pipelines containing optical fiber cable and the operation and maintenance of the optical fiber system. 1.2 This practice applies to distribution and service lines used to transport natural gas. 1.3 This practice does not apply to natural gas transmission lines. 1.4 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== This practice is intended to assist optical fiber cable owners and pipeline operators in developing operating and maintenance procedures and practices for the secondary use of gas pipelines as conduits for optical fiber cables. It must be kept in mind that the primary use of gas pipelines is for transportation of natural gas and any secondary use of the system must not materially impact the primary function. It is the responsibility of the optical fiber cable owner and pipeline operator to decide how best to integrate operating and maintenance procedures for the pipeline, the optical fiber system, and the optical fiber cable so that safety is not compromised, customers are served in the best way possible, and incremental costs are minimized. Since the practice of integrating gas pipeline facilities and fiber optics for telecommunications purposes is a new and emerging activity, this standard will help establish guidelines for its rapid and safe deployment and will ensure that the facilities installed are maintained to operate on a long-term basis.
