Plastics piping systems - Fittings, valves and ancillaries - Determination of gaseous flow rate/pressure drop relationships

This standard specifies a method for determining the flow rate/pressure drop relationship of components for plastics piping when tested using air at 25 mbar.It is applicable to mechanical fittings, valves, tapping tees and other ancil- laries intended to be used in polyethylene (PE) piping systems for supply of gaseous fuels. The data obtained may be used to calculate the flow of such gases for a specified pressure drop.

Kunststoff-Rohrleitungssysteme - Formstücke, Armaturen und Zubehörteile - Bestimmung des Zusammenhanges zwischen Gasdurchfluß und Druckabfall

Diese Norm legt ein Verfahren für die Bestimmung des Zusammenhanges zwischen Gasdurchfluß und Druckabfall der Komponenten für Kunststoffrohrleitungen fest,wenn sie mit Luft bei 25 mbar geprüft werden. Sie ist auf mechanische Form- stücke, Armaturen, Anbohrschellen und andere Zubehörteile anwendbar, die zur Verwendung in Polyethylen (PE) Kunststoff-Rohrleitungssystemen für die Gas- versorgung vorgesehen sind. Die erhaltenen Daten können verwendet werden, um die Fließgeschwindigkeit solcher Gase für einen bestimmten Druckabfall zu berechnen.

This document provides guidance and information for drafting product standards to specify characteristics and test methods for the utilisation of thermoplastics recyclates (PVC-U, PVC-C, PE, PP, ABS) in pipes, fittings and ancillaries for thermoplastics piping systems.
This document covers recyclates with an agreed specification from all sources.
Note 1: This document does not cover characteristics for reworked material
Note 2: This document does not cover recycling processes (e.g. chemical or mechanical)
Note 3: This document does not define if recycled material can be used in a specific application. The possible use of recyclates will be defined in the applicable product standard.
This document provides guidance about the relevant characteristics to be included in the agreed specification for recyclates.
This document is applicable without prejudice to any existing legislation.
For the recycling process, transport, the testing and the use of thermoplastics recyclates National and/or European regulations (e.g. hygienic aspects) may apply.
Note 4: For example threshold levels for substances of very high concern (SVHC) as defined in the REACH-legislation which can possibly be present in thermoplastic recyclates.
