What is BS EN 13617-2 - Safety criteria for metering pumps and dispensers' safe breaks about?
BS EN 13617-2 specifies safety requirements for the construction and performance of safe breaks to be fitted to metering pumps and dispensers installed at filling stations and used to dispense liquid fuels and aqueous urea solution into the tanks of motor vehicles, boats and light aircraft and into portable containers at flow rates up to 200 l · min−1.
BS EN 3617-2 applies to fuels of subdivision Group IIA according to EN ISO/IEC 80079-20-1 and also aqueous urea solution according to ISO 22241-1.
The requirements apply to safe breaks at ambient temperatures from −20 °C to +40 °C with the possibility for an extended temperature range.
BS EN 13617-2 pays particular attention to electrical, mechanical, and hydraulic characteristics of, and electrical equipment incorporated within or mounted on, the safe break.
BS EN 13617-2 applies mainly to hazards related to the ignition of liquid fuels being dispensed or their vapor. BS EN-13617-2 also addresses electrical and mechanical hazards.
NOTE: BS EN 13617-2 does not apply to equipment dispensing compressed or liquefied gases.
Who is BS EN 13617-2 - Safety criteria for metering pumps and dispensers' safe breaks for?
BS EN 13617-2 on Safety requirements for construction and performance of safe breaks for use on metering pumps and dispensers are beneficial for:
- Petrol pump attendants
- Gas jockeys
- Fuel attendants
- Construction sectors
- Civil engineers and contractors
- Pharmaceutical industries
- Petroleum industries, petrochemical and gas industries
- Locksmiths
- Safe technicians
Why should you use BS EN 13617-2 - Safety criteria for metering pumps and dispensers' safe breaks?
Metering pumps, also called dosing pumps, are pumps that are designed to dispense specific amounts of fluid and measure flow control. They use expanding and contracting chambers to move the liquids.
BS EN 13617-2 assists the user with requirements for the construction and performance of safe breaks to be fitted to metering pumps and dispensers installed at filling stations which is useful for dispensing liquid fuels and aqueous urea solution into the tanks of motor vehicles.
BS EN 13617-2 pays particular attention to electrical, mechanical, and hydraulic characteristics of, and electrical equipment incorporated within or mounted on, the safe break.
Overall, BS EN 13617-2 gives complete guidance on the requirements for construction and performance of safe breaks for use on metering pumps and dispensers which can be very helpful for your business. For fuel safe breaks, preconditioning mechanical impact tests are conducted immediately after removal from the saturated atmosphere. Environmental aspects are kept in mind.
What’s changed since the last update?
BS EN 13617-2: 2021 supersedes BS EN 13617 2:2012, which is withdrawn.
In comparison with the 2012 edition, the following significant changes were made:
- Safe breaks for aqueous urea solution added
- The production acceptance tests are modified to test at least every 500th unit
- The liquid compatibility preconditioning fluid for fuel safe breaks is defined in EN 13617-1
