Plastics piping systems for the supply of gaseous fuels - Unplasticized polyamide (PA-U) piping systems with fusion jointing and mechanical jointing - Part 4: Valves (ISO 16486-4:2022)

This document specifies the characteristics of valves made from unplasticized polyamide (PA-U) in accordance with ISO 16486-1, intended to be buried and used for the supply of gaseous fuels.
It is applicable to isolating unidirectional and bi-directional valves with spigot ends or electrofusion sockets intended to be fused with PA-U pipes or fittings conforming to ISO 16486-2 and ISO 16486-3 respectively.
Valves made from material other than unplasticized polyamide designed for the supply of gaseous fuels conforming to the relevant standards are permitted to be used in PA-U piping systems according to the ISO 16486 series provided they have relevant PA-U connections for butt fusion or electrofusion ends (see ISO 16486-3). The component, i.e. the complete valve, is required to fulfil the requirements of this document.
This document also specifies the test parameters for the test methods it describes.
In conjunction with ISO 16486-1, ISO 16486-2, ISO 16486-3 and ISO 16486-5, this document is applicable to PA-U valves and their joints and to joints with components of PA-U and other materials intended to be used under the following conditions:
a) a maximum operating pressure (MOP) of up to and including 18 bar[1], or limited to 16 bar under regional CEN requirements, at a reference temperature of 20 °C for design purposes;
NOTE 1    For the purpose of this document and the references to ISO 8233, MOP is considered to be nominal pressure.
b) an operating temperature of −20 °C to 40 °C;
NOTE 2    For operating temperatures between 20 °C and 40 °C, derating coefficients are specified in ISO 16486-5.
This document covers valves for pipes with a nominal outside diameter, dn, ≤ 400 mm.
[1] 1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm².

Kunststoff-Rohrleitungssysteme für die Gasversorgung - Rohrleitungssysteme aus weichmacherfreiem Polyamid (PA-U) mit Schweißverbindungen und mechanischen Verbindungen - Teil 4: Armaturen (ISO 16486-4:2022)

Dieses Dokument legt die Eigenschaften von Armaturen fest, die nach ISO 16486 1 aus weichmacherfreiem Polyamid (PA U) hergestellt sind und unterirdisch verlegt und für die Gasversorgung verwendet werden sollen.
Es ist anzuwenden für Absperrarmaturen mit einer und mit zwei Durchflussrichtungen, die über Schweißenden oder Heizwendelschweißmuffen verfügen, und dafür vorgesehen sind, mit Rohren oder Formstücken aus PA U nach ISO 16486 2 bzw. ISO 16486 3 verschweißt zu werden.
Armaturen aus einem anderen Werkstoff als weichmacherfreiem Polyamid für die Gasversorgung, die den jeweiligen Normen entsprechen, dürfen nach der Normenreihe ISO 16486 in PA U Rohrleitungssystemen verwendet werden, wenn sie über jeweilige PA U Anschlüsse für Stumpfschweiß- oder Heizwendel¬schweißenden verfügen (siehe ISO 16486 3). Das Bauteil, d. h. die vollständige Armatur, muss die Anforderungen dieses Dokuments erfüllen.
Dieses Dokument legt auch die Prüfparameter für die beschriebenen Prüfverfahren fest.
In Verbindung mit ISO 16486 1, ISO 16486 2, ISO 16486 3 und ISO 16486 5 ist dieses Dokument anzuwenden für Armaturen aus PA U und deren Verbindungen untereinander sowie mit Rohrleitungsteilen aus PA U und anderen Werkstoffen, die für die Verwendung unter den folgenden Bedingungen vorgesehen sind:
a)   ein maximal zulässiger Betriebsdruck (MOP, en: maximum operating pressure) bis einschließlich 18 bar  oder unter regionalen CEN Anforderungen begrenzt auf 16 bar, bei einer Bezugstemperatur von 20 °C für Auslegungszwecke;
ANMERKUNG 1   Für die Anwendung dieses Dokuments und der Verweisungen auf ISO 8233 wird MOP als Nenndruck angesehen.
b)   eine Betriebstemperatur von −20 °C bis 40 °C.
ANMERKUNG 2   Für Betriebstemperaturen von 20 °C bis 40 °C sind die Abminderungskoeffizienten in ISO 16486 5 festgelegt.
Dieses Dokument behandelt Armaturen für Rohre mit einem Nenn-Außendurchmesser dn ≤ 400 mm.

Systèmes de canalisations en matières plastiques pour la distribution de combustibles gazeux - Systèmes de canalisations en polyamide non plastifié (PA-U) avec assemblages par soudage et assemblages mécaniques - Partie 4: Robinets (ISO 16486-4:2022)

Le présent document spécifie les caractéristiques des robinets en polyamide non plastifié (PA-U) conformément à l’ISO 16486-1, destinés à être enterrés et utilisés pour la distribution de combustibles gazeux.
Il s’applique aux robinets d’isolement unidirectionnels et bidirectionnels avec des extrémités à bout mâle ou des emboîtures électrosoudables prévues pour être soudées à des tubes ou à des raccords en PA-U conformes à l’EN ISO 16486-2 et à l’EN ISO 16486-3 respectivement.
Il est autorisé d’utiliser des robinets constitués d’un autre matériau que le polyamide non plastifié, conçus pour la distribution de combustibles gazeux et conformes aux normes pertinentes pour le système de canalisations en PA-U selon la série ISO 16486, à condition qu’ils aient des raccords en PA-U appropriés pour les extrémités soudées bout à bout ou électrosoudables (voir l’ISO 16486-3). Le composant, c’est-à-dire le robinet complet, doit satisfaire aux exigences du présent document.
Le présent document spécifie également les paramètres d’essai pour les méthodes d’essai qu’il décrit.
Conjointement avec ISO 16486-1, l’ISO 16486-2, l’ISO 16486-3 et l’ISO 16486-5, le présent document s’applique aux robinets en PA-U et à leurs assemblages, ainsi qu’aux assemblages avec des composants en PA-U et en d’autres matières destinés à être utilisés dans les conditions suivantes:
a) une pression maximale de service (MOP), inférieure ou égale à 18 bar,[1] , ou limitée à 16 bar en tant qu’exigence régionale du CEN, à une température de référence de 20 °C pour les besoins des calculs;
NOTE 1        Pour les besoins du présent document et en référence à ISO 8233 la MOP est considérée comme la pression nominale.
b) une température de service de –20 °C et 40 °C;
NOTE 2        Pour des températures de service comprises entre 20 °C et 40 °C, les facteurs de réduction sont spécifiés dans l’ISO 16486-5.
Le présent document couvre les robinets conçus pour être raccordés à des tubes d’un diamètre extérieur nominal dn ≤ 400 mm.
[1] 1 bar = 0,1 MPa = 105 Pa ; 1 MPa = 1 N/mm2.
