DIN EN 14125:2013-09

This standard (EN 14125:2013) has been prepared by Technical Committee CEN/TC 393/WG 6 "Equipment for storage tanks and for filling stations" (secretariat: DIN, Germany), Working Group WG 6 "Underground pipework systems for petrol filling stations" (secretariat: BSI, United Kingdom). The responsible German body involved in its preparation was Steering Committee NA 104-02 FBR "Fachbereichsbeirat Ausrüstung für Tanks" ("Steering Committee of the Section Equipments for Tanks") of the Tank Installations Standards Committee (NATank) of DIN, the German Institute for Standardization e. V. This European Standard specifies requirements for underground 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 degree 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 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. Compared with edition 2007, the following fundamental changes are given: - new definitions included; - new types of secondary containment included; - multilayer pipes included; - requirements for static electricity revised; - new test fuels added; - test procedures revised. This standard contains an A-deviation in Annex A (informative) regarding permeation for Germany.
