Plastics piping systems for the supply of gaseous fuels — Unplasticized polyamide (PA-U) piping systems with fusion jointing and mechanical jointing — Part 1: General

This document specifies the general properties of unplasticized polyamide (PA-U) compounds for the manufacture of pipes, fittings and valves made from these compounds, intended to be buried and used for the supply of gaseous fuels. It also specifies the test parameters for the test methods to which it refers. The ISO 16486 series is applicable to PA-U piping systems, the components of which are connected by fusion jointing and/or mechanical jointing. This document establishes a calculation and design scheme on which to base the maximum operating pressure (MOP) of a PA-U piping system. NOTE For the purpose of this document the term gaseous fuels includes, for example, natural gas, methane, butane, propane, hydrogen, manufactured gas, biogas, and mixtures of these gases.

Plastics piping systems for the supply of gaseous fuels - Unplasticized polyamide (PA-U) piping systems with fusion jointing and mechanical jointing — Part 6: Code of practice for design, handling and installation

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.). Workers' health and safety issues are outside the scope of this document

Plastics piping systems for the supply of gaseous fuels — Unplasticized polyamide (PA-U) piping systems with fusion jointing and mechanical jointing — Part 7: Assessment of conformity

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. [1] 1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2.
