标准范围

本文件规定了处理建筑物外埋地管道系统的未增塑聚酰胺（PA-U）管道和配件的实施规范，这些管道和配件用于运输气体燃料（如ISO？16486-1中定义的，例如甲烷、液化石油气、人造气体和氢气）。温度范围-20？°C到+40？°C。该文件还给出了适当的温度相关要求。该业务守则涵盖其组件准备熔合或机械连接的干线和服务管线，并就PA-U管道和配件的设计、储存、处理、运输、铺设条件和熔合质量控制以及随后的接头测试、回填、管道系统测试和调试提供了指导。笔记？康复的主要信息可以在ISO 11295中找到分类，ISO 11299-1和ISO 11299-2用于翻新，ISO 21225-1和ISO 21225-2用于非开挖更换。可以存在更详细的国家标准或行为准则。本文件旨在与与上述基本原则有关的此类国家标准或业务守则一并适用。本文件涵盖的连接方法有:—？对接熔接（见附件？A）；—？电熔接（见附录B）和—？机械连接（见附录？C）。在地面运动或摇晃（如地震等）的情况下。）本文件中提到的预防措施可能需要按照权威机构提供的指南（如EN 1998-4、EN 12007-1:20 12、附录A？等等。）.工人的健康和安全问题超出了本文件的范围

This document specifies a code of practice dealing with unplasticized polyamide (PA-U) pipes and fittings for buried pipeline systems outside buildings and designed to transport gaseous fuels (as defined in ISO 16486-1, e.g. methane, LPG, manufactured gas and hydrogen) within the temperature range –20 °C to +40 °C. This document also gives appropriate temperature-related requirements.

The code of practice covers mains and service lines whose components are prepared for fusion or mechanical jointing and gives instructions for the design, storage, handling, transportation, laying conditions and fusion quality control of PA-U pipes and fittings as well as subsequent joint testing, backfilling, pipe system testing and commissioning.

NOTE          Principal information for rehabilitation can be found in ISO 11295 for classification, ISO 11299-1 and ISO 11299-2 for renovation, and ISO 21225-1 and ISO 21225-2 for trenchless replacement.

More detailed national standards or codes of practice can exist. This document is intended to be applied in association with such national standards or codes of practice related to the above-mentioned basic principles.

The jointing methods covered by this document are:

—     butt fusion jointing (see Annex A);

—     electrofusion jointing (see Annex B) and

—     mechanical jointing (see Annex C).

In the case of ground movement or shaking (e.g. earthquakes, etc.) precautions mentioned in this document can need to be implemented following guidelines provided by authorities (e.g. EN 1998-4, EN 12007-1:2012, Annex A etc.).
