BS EN 14125:2013EN 14125:2013 (E) 5 Introduction The purpose of this document is to ensure the suita

23、bility of underground pipework for conveying liquid fuels and their vapours at petrol filling stations. Pipework should have a designated means of fitting specified by the manufacturer or supplier. Pipework for underground installation at petrol filling stations generally has a diameter less than 10

24、0 mm and is therefore outside the scope of the Pressure Equipment Directive (PED) 97/23/EC. Pipework with an internal diameter greater than or equal 100 mm could be within the scope of the PED. BS EN 14125:2013EN 14125:2013 (E) 6 1 Scope This European Standard specifies requirements for underground

25、pipework systems used to transfer liquid fuels and their vapours at petrol filling stations. Minimum performance requirements covering fitness for purpose, safety and environmental protection are given. This European Standard applies to pipework made from thermoplastics, which may include some degre

26、e of reinforcement, and to flexible metal pipework. It does not apply to fibre reinforced thermosets, commonly referred to as glass fibre reinforced plastic (GRP), nor to rigid metals. This document applies to: delivery pipes from tanks to dispensers, including positive pressure, vacuum suction and

27、siphon modes; fill pipes from road tankers to tanks; vapour recovery and vent pipework; pipework for secondary containment; fittings. It does not apply to pipework for use with liquefied petroleum gas. 2 Normative references The following documents, in whole or in part, are normatively referenced in
