CEN/TC 47/WG 4 - Oil supply systems

This European Standard specifies the safety and performance requirements and tests methods for the components for supply systems. Their intended use is the supply with liquid fuel for one or more consuming units from one or more tanks.
This European Standard applies to pressurised, negative pressurised, unpressurised, underground, above ground, inside and/or outside systems to supply liquid fuels.
The components for supply systems covered by this standard are piping kits/systems and their components.
Not covered by this standard are items belonging to the consuming unit (e. g.: heating/cooling appliances in buildings) and items used for the mounting and support of components.
Not covered by this standard are items with the intended use of gas for building heating/cooling systems and any items of heating networks.
Not covered are items used for drainage (including highways) and disposal of other liquids and gaseous waste, supply of gases, pressure and vacuum systems, communications, sanitary and cleaning fixtures and storage fixtures.

This Technical Report includes application-relevant metallic materials of supply systems for liquid fuels and their blends with regard to corrosive or service life reducing influences. Assessment of the specialist literature showed possible interactions with biogenic and alternative fuels and motor fuels as well as their blends with mineral oil and motor fuels. The results of this assessment are given in this CEN/TR.

This European Standard applies to all parts of supply systems for the automatic supply of liquid fuel to one or more consuming units from one or more tanks. It applies to all parts from the tank connection(s) to the connection to the burner or the consuming units, respectively, including the direct series-connected shut-off devices.

This European Standard applies to the following parts of supply systems for the automatic liquid fuel supply of consuming units from one or more tanks:
a)   pipes;
b)   fasteners;
c)   pipeline connections;
d)   parts within pipes;
Combinations of single parts are acceptable.

This European Standard applies to the following parts of supply systems for the automatic supply of liquid fuel to one or more consuming units from one or more tanks:

This standard applies to valves, pipes, filters and meters of oil supply installations for automatic supply of one or more oil burners or oil consuming units with fuel oil from one or more central storage tanks under static or dynamic pressure. This standard covers all the above mentioned components between the connection to one or more tanks and the connection to oil burners or oil consuming units, including the direct series-connected shut-off devices.

This standard applies to oil feed pumps, oil supply tanks and corresponding control and safety devices of oil supply installations for automatic supply of one or more oil burners or oil consuming units with light fuel oil (maximum viscosity of 10 mm2/s at a temperature of 20°C) from one or more central storage tanks under static or dynamic pressure.
