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/DIS 16486-4:2024)
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.

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.
