Description of 21/30405789 DC 2021

This part of ISO 16486 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 PE pipes or fittings conforming to EN ISO 16486-2 and EN ISO 16486-3 respectively.

Valves made from other material than unplasticized polyamide designed for the supply of gaseous fuels conforming to the relevant standards are permitted to be used in PA-U piping system according to ISO 16486 provided they have relevant PA-U connections for butt fusion or electrofusion ends (see ISO 16486 3). The component, i.e. the complete valve, shall fulfil the requirements of this part of ISO 16486.

It also specifies the test parameters for the test methods referred to in this part of ISO 16486.

In conjunction with Parts 1, 2, 3 and 5 of ISO 16486 EN-1555, it is applicable to PA-U PE valves, their joints and to joints with components of PA-U PE and other materials intended to be used under the following conditions:

  1. a maximum operating pressure, MOP, up to and including 18 bar1

    1

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

    or as regional CEN requirement limited to 16 bar, at a reference temperature of 20 °C for design purposes;

    NOTE 1

    For the purpose of this document and the references to ISO/DIS 8233, MOP is considered to be nominal pressure.

  2. an operating temperature of between -20 °C to 40 °C;

    NOTE 2

    For operating temperatures between 20 °C and 40 °C, derating coefficients are defined in ISO DIS 16486-5.

ISO 16486 (all parts) covers a range of maximum operating pressures and gives requirements concerning colours.

NOTE 3

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.

It is applicable to bi-directional valves with spigot end or electrofusion socket intended to be jointed with PA-U pipes conforming to ISO 16486-2 without any fittings or with PA-U fittings conforming to ISO 16486 3.

This part of ISO 16486 covers valves for pipes with a nominal outside diameter, dn, ≤400 mm.
