What is BS EN-13617-4 about?
BS EN-13617-4 specifies safety requirements for the construction and performance of swivels to be fitted to delivery hose assemblies. It includes delivery hose assemblies fitted on metering pumps and dispensers installed at filling stations that are used to dispense liquid fuels and aqueous urea solution into the tanks of various vehicles and into portable containers at flow rates up to 200I.min−1.
The requirements apply to swivels at ambient temperatures from −20 °C to +40 °C with the possibility for an extended temperature range.
BS EN-13617-4 applies mainly to hazards related to the ignition of liquid fuels being dispensed or their vapour. BS EN-13617-4 also addresses electrical and mechanical hazards of swivels.
BS EN-13617-4 applies to fuels of subdivision Group IIA according to EN ISO/IEC 80079-20-1 and aqueous urea solution in accordance with ISO 22241-1.
NOTE: BS EN-13617-4 does not apply to equipment dispensing compressed or liquefied gases.
Who is BS EN-13617-4 for?
BS EN-13617-4 on safety requirements of swivels used at metering pumps and dispensers is relevant to:
- Manufacturers and installers of swivels
- Petrochemical and gas industry
- Management/regulatory authorities of petrol filling stations
Why should you use BS EN-13617-4?
Metering pumps are pumps that are designed to dispense specific amount of fluid and measured flow control. They use expanding and contracting chambers to move the liquids.
BS EN-13617-4 is useful as it guides you with the safety requirements for the construction and performance of swivels through distinct types of tests like electrical resistance test, burst test, drop test, leak test. Compliance to these testing parameters will help you avoid product failure that could lead to fuel spillage and damage to the equipment. Thus, you will be assured of operationally efficient and safe-to-use swivels.
Given the potentially explosive atmosphere, it is vital to ensure all electrical and non-electrical equipment and components, intended for use at petrol filling stations are designed and constructed according to good engineering practice to ensure avoidance of any ignition source. BS EN 12617-4 is your one-stop guide to ensure the same.
What’s changed since the last update?
BS EN-13617-4: 2021 supersedes BS EN 13617‑4:2012, which is withdrawn. In comparison with the 2012 edition, the following significant changes were made:
- Swivels for aqueous urea solution added
- Table 1 corrected to ensure compatibility between components according to EN13012:2021, EN 13617-2:2021, EN 13617-4:2021, and EN 1360:2013
- The liquid compatibility preconditioning fluid for shear valves is defined in EN 13617-1
