16、e This Technical Report provides guidance and recommendations to enable the transfer of product and vapour between the loading gantry, the tank truck and the service station. The European Parliament and Council Directive 94/63/EC (VOC Directive) requires operators to ensure that petroleum vapours ar
17、e not emitted into the atmosphere during loading and unloading. The recommendations and guidance given in this document are intended to assist users in meeting the requirements of this Directive. This Technical Report acknowledges that, for climatic and logistical reasons alternative technical solut
18、ions are commonly used in the Arctic Region. This Technical Report gives guidance and recommendations for loading at terminals and discharge at service stations or customer premises of tank trucks transporting dangerous goods (liquid petroleum fuels) which have a vapour pressure not exceeding 110 kP
19、a, at 50 C (including petrol), and which have no sub- classification as toxic or corrosive. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest editi

21、the terms and definitions given in EN 14564:2004 and the following apply. 3.1 arctic region region comprising Finland, Norway and Sweden 3.2 authorization to load authorization of a tank truck loader by a terminal operator to load the required goods into the tank truck following the verification of
22、his or her competence including any required certification and its associated validity 3.3 driver person in charge of the tank truck, having responsibility for driving and who might or might not also be responsible for its loading and/or discharge 3.4 overfill filling of a tank truck or one or more
23、of its compartments to the extent that the total volume loaded into a compartment exceeds the maximum permitted volume PD CEN/TR 15120:2005 Licensed Copy: Wang Bin, na, Tue Apr 25 03:07:04 BST 2006, Uncontrolled Copy, (c) BSI5 3.5 overfill prevention system gantry-mounted controller connected to sen
24、sors mounted at a pre-determined high level in a tank truck that will, in the event that a sensor detects liquid, signal the gantry control valve to cease loading flow in order to prevent the overfilling of the tank truck 3.6 overloading loading of a tank truck such that its total weight exceeds tha
25、t permitted by local road regulations, or the load imposed by one or more axles exceeds the local maximum authorized weight for that axle 3.7 tank truck truck which conforms to the definition of either tank-vehicle, demountable tank, tank container or tank swap body given in EN 14564 3.8 safe loadin

30、nk trucks, equipped according to this document, should be available on at least one gantry at each arctic loading facility. PD CEN/TR 15120:2005 Licensed Copy: Wang Bin, na, Tue Apr 25 03:07:04 BST 2006, Uncontrolled Copy, (c) BSI6 4.1.2 Overfill prevention system Loading gantries should have meters
31、 to determine the volume loaded into a tank truck compartment. The primary overfill prevention system should comprise the pre-setting of the gantry loading meter by the tank truck loader for each tank truck compartment separately before it is loaded. 4.1.3 Level detection Secondary shut off (overfil
32、l prevention) system The gantry-based components of the overfill prevention system should conform to EN 13922. The plug should be able to connect with the connector within the tank connection envelope as described in Annex A. It should be considered as a secondary overfill prevention system in the e
33、vent that the primary volume limiting system (meter pre-set) does not operate. NOTE In the arctic region, 2-wire thermistor sensors with a positive temperature coefficient conforming to national standards and individual tank truck mounted shut-off devices are commonly used. 4.1.4 Coupler for bottom
34、loading Couplers for bottom loading should be operationally compatible with adaptors for bottom loading and should be able to connect with them within the tank connection envelope as described in Annex A. Where tank trucks fitted with valves which can be closed against product flow are loaded, a sur
35、ge pressure of 2 500 kPa should not compromise the integrity or functions of the coupler. In order to prevent the accumulation of any electrostatic charge, there should be electrical resistance of less than 10 ohms across a metallic coupler and adaptor, and less than 10 6ohms in other cases, when co
36、nnected. NOTE In the arctic region, couplers for bottom loading with the same functionality but able to connect with an adaptor for bottom loading with a reduced diameter are commonly used. 4.1.5 Vapour collection system The vapour collection coupler should conform to EN 13081 and should be able to
37、connect with the vapour collection adaptor within the tank connection envelope as described in Annex A. NOTE In the arctic region, a vapour collection coupler with the same functionality but with a reduced diameter are commonly used. 4.1.6 Drive away restriction A system to prevent unauthorized move
38、ment of a tank truck may be provided. 4.2 Loading conditions 4.2.1 Maximum loading rates per loading arm The maximum loading rate per loading arm should not exceed the values given in Table 1. It is recommended that the tank truck be suitable for high speed loading (see 5.2.1). NOTE Table 1 has been
39、 adapted from CLC/TR 50404 and gives the flow rates for diameters of pipe used in loading systems including tank truck pipe work such that the accumulation of the electrostatic charge on the surface of the liquid does not exceed acceptable limits. Maximum loading rates (vd 0,5) are given for design
40、purposes; loading rates may be reduced for safety reasons depending upon specific circumstances. The reduced values given in brackets apply to non high speed loading tank trucks.

NOTE 3 Values in brackets apply to non high speed loading tank-vehicles. NOTE 4 The maximum loading rates given in

45、eed 1 Mpa; pressure-balanced footvalves conform to EN 13316. 4.2.3 Maximum vapour back pressure The maximum back-pressure created by the gantry vapour recovery system should be 5,5 kPa (55 mbar). NOTE 1 The maximum back pressure of 5,5 kPa is a requirement of the VOC Directive 94/63/EC. NOTE 2 Contr
46、ols may be provided to ensure that this maximum back pressure is not exceeded. PD CEN/TR 15120:2005 Licensed Copy: Wang Bin, na, Tue Apr 25 03:07:04 BST 2006, Uncontrolled Copy, (c) BSI8 4.3 Loading operations Before loading is permitted, procedures should exist to ensure that there is authorization
47、 to load and to accommodate the loading of both empty and not-empty compartments. For not-empty compartments, the volume and grade of the retained goods should be determined prior to loading. If the surface on which the tank truck is standing is not conductive (see CLC/TR 50404 for guidance), the ta
48、nk truck should be bonded to earth before any operation (for example opening fill covers, connecting loading couplers) is carried out. The bonding resistance between the tank truck and the gantry should be 10 6ohms or less. Procedures should exist to ensure that overloading does not occur. 5 Tank tr
