Voorbeeldzinnen

1. The filling unit shall withstand a pressure of 33 MPa.
2. A damping chamber shall be installed at the exit of the multiple tube unit to minimise the pressure oscillations in the exhaust pipe EP.
3. The tank must be subjected to a hydraulic internal pressure test which must be carried out on an isolated unit complete with all its accessories.
4. A damping chamber must be installed at the exit of the multiple tube unit to minimise the pressure oscillations in the exhaust pipe EP.
5. in the case of more than one storage site in the same hydraulic unit, the potential pressure interactions are such that both sites can simultaneously meet the requirements of this Directive;
6. The flow through the filling unit, with the non-return valve mechanically opened, at a pressure difference of 50 kPa shall be at least 200 litres/min, when tested with water.
7. For a multi tube system (Figure 17), a flow controller is necessary for proportional exhaust splitting to maintain a differential pressure of zero between the exit of the multi tube unit and the exit of TT.
8. For a multi-tube system (Figure 17), a flow controller is necessary for proportional exhaust splitting to maintain a differential pressure of zero between the exit of the multi-tube unit and the exit of TT.
9. The seat of the upper non-return valve used in the assembly of a filling unit, when in the closed position, shall be free from leakage at any aerostatic pressure between 50 and 3000 kPa.
10. .20 Oil fuel unit is the equipment used for the preparation of oil fuel for delivery to an oil-fired boiler, or equipment used for the preparation for delivery of heated oil to an internal combustion engine, and includes any oil pressure pumps, filters and heaters dealing with oil at a pressure of more than 0,18 N/mm2.
11. ‘hydraulic unit’ means a hydraulically connected pore space where pressure communication can be measured by technical means and which is bordered by flow barriers, such as faults, salt domes, lithological boundaries, or by the wedging out or outcropping of the formation;
12. Directive 92/42/EEC defines useful efficiency (expressed in %) as the ratio between the heat output transmitted to the boiler water and the product of the net calorific value at constant fuel pressure and the consumption expressed as a quantity of fuel per unit time.
13. In the case of an engine equipped with a particulate filter, examples of monitoring for major functional failure are for major melting of the trap substrate or a clogged trap resulting in a differential pressure out of the range declared by the manufacturer, any electrical failure of a component (e.g. sensors and actuators, dosing control unit) of a particulate filter, any failure, when applicable, of a reagent dosing system (e.g. clogged nozzle, dosing pump failure).
14. The LPG combustion heater shall comply with the requirements of the harmonised standard on specifications for dedicated LPG appliances — Room sealed LPG space heating equipment for installation in vehicles and boats (EN 624:2000).1.1.2. In cases of a permanently installed LPG container all components of the system that are in contact with LPG in the liquid phase (all components from the filling unit to the vaporiser/pressure regulator) and the associated liquid phase installation shall comply with the technical requirements of UN/ECE Regulation No 67, Parts I and II and the Annexes 3 to 10, 13 and 15 to 17.
