标准范围

本文件为根据ISO 16486系列的适用部分评估化合物、产品、接头和组件的符合性提供了指导和要求，这些部分旨在作为质量管理体系的一部分纳入制造商的质量计划，并用于建立认证程序。注1？附录中的基本测试矩阵？B提供了测试方案的概述。建议制造商拥有ISO 9001[4]或同等标准的管理体系。笔记？2？如果涉及认证，按照ISO/IEC运作的认证机构和检验机构？17065和ISO/IEC？17020被认为是合格的。连同ISO 16486系列的其他部分（见条款？2），本文件适用于未增塑聚酰胺（PA-U)打算埋在地下并用于供应气体燃料的管道系统。它适用于PA-U管道、配件和阀门，以及它们的接头和与打算在下列条件下使用的其他材料部件的接头:A）？最大工作压力（MOP）不超过18？酒吧[1]（MOP限于16？bar适用于CEN成员国，其中ISO？16486-6被CEN/TS 12007-6[1]取代）；b）？工作温度为20？℃作为参考温度。注3？对于不同于20的工作温度？℃时，可以使用降额系数（参见ISO 16486-6）。CEN成员国使用CEN/TS 12007-6[1]和ISO/TS 16486-7（本文件）作为基础，但也可以要求附加要求。对于非CEN成员国，处理PA特殊情况的信息-U可在ISO/TS 16486-7（本文件）和PPI TR-3中找到。[7]对于符合ISO 17885的机械配件，本文件中未给出合格评定指南。根据要求，用户和制造商可以根据上述测试制定质量计划。ISO 16486系列涵盖了一系列最大工作压力，并给出了有关颜色的要求。注4？买方或指定方有责任从这些方面做出适当的选择，同时考虑其特殊要求以及任何相关的国家法规和安装惯例或规范。[1]1？酒吧？=？0,1？MPa？=？105？Pa;1？MPa？=？1？N/mm2。

This document gives guidance and requirements for the assessment of conformity of compounds, products, joints and assemblies in accordance with the applicable part(s) of the ISO 16486 series which are intended to be included in the manufacturer’s quality plan as part of the quality management system and for the establishment of certification procedures.

NOTE 1    A basic test matrix in Annex B provides an overview of the testing scheme.

It is recommended for the manufacturer to have a management system such as ISO 9001^[4] or equivalent.

NOTE 2    If certification is involved, certification bodies and inspection bodies operating according to ISO/IEC 17065 and ISO/IEC 17020 are considered to be competent.

In conjunction with the other parts of the ISO 16486 series (see Clause 2), this document is applicable to unplasticized polyamide (PA-U) piping systems intended to be buried and used for the supply of gaseous fuels. It is applicable to PA-U pipes, fittings and valves, as well as to their joints and to joints with components of other materials intended to be used under the following conditions:

a)    a maximum operating pressure (MOP) up to and including 18 bar[1] (the MOP is limited to 16 bar for CEN member countries, where ISO 16486-6 is replaced by CEN/TS 12007-6^[1]);

b)    an operating temperature of 20 °C as the reference temperature.

NOTE 3    For operating temperatures different to 20 °C, derating coefficients can be used (see ISO 16486-6). CEN member countries use CEN/TS 12007-6^[1] and ISO/TS 16486-7 (this document) as a basis, but they can also request additional requirements. For non-CEN member countries, information for dealing with special cases for PA-U can be found in ISO/TS 16486-7 (this document) and PPI TR-3.^[7]

For mechanical fittings conforming to ISO 17885, guidance for assessment of conformity is not given in this document. When requested, a quality plan based on the tests mentioned can be set up in agreement between user and manufacturer.

The ISO 16486 series covers a range of maximum operating pressures and gives requirements concerning colours.

NOTE 4    It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes.
