DIN EN 13081:2012-05 EN 13081:2008+A1:2012 (E) 5 Introduction The vapour collection adaptor and coupler are part of the
28、 vapour collection system that is required to comply with the European Directive 94/63/EC on Volatile Organic Compounds (VOC) 1. The vapour collection adaptor and coupler establish a vapour tight path between the transport tank and the stationary loading and unloading facilities. DIN EN 13081:2012-0
29、5 EN 13081:2008+A1:2012 (E) 6 1 Scope This European Standard covers the vapour collection adaptor and coupler used to achieve a vapour tight path between the transport tank and the stationary loading and unloading facilities. This European Standard specifies the performance requirements and the crit
30、ical dimensions of the vapour recovery adaptor fitted to the tank and the mating coupler fitted to a hose or to pipework connected to the stationary loading and unloading facilities. It also specifies the tests necessary to verify the compliance of the equipment with this standard. The equipment spe
31、cified by this European Standard is suitable for use with liquid petroleum products and other dangerous substances of Class 3 of ADR 2 which have a vapour pressure not exceeding 110 kPa, at 50 C and petrol, and which have no sub-classification as toxic or corrosive. 2 Normative references The follow

36、Working Pressure (MWP) gauge pressure maximum pressure to which the equipment is designed to operate, being the highest of the following three pressures: a) highest effective pressure allowed in the tank during filling (maximum filling pressure allowed) b) highest effective pressure allowed in the t
37、ank during discharge (maximum discharge pressure allowed) c) effective gauge pressure to which the tank is subjected by its contents (including such extraneous gases as it may contain) at the maximum working temperature DIN EN 13081:2012-05 EN 13081:2008+A1:2012 (E) 7 !3.2 probe device used to displ
38、ace the obturator (poppet) of the adaptor“ 4 Function The vapour collection adaptor and coupler shall provide the following: a quick action vapour tight mechanical connection between the transport tank and the stationary loading and unloading facilities for the transfer of vapour; vapour tightness w
39、hen not connected. The vapour collection adaptor may be capable of accepting interlock actuators and similar devices, see Annex C. The vapour collection adaptor may have provision for a sight glass to check for the presence of liquid. The vapour collection adaptor may have provision for the drainage
40、 of liquid. 5 Design characteristics 5.1 General The vapour collection adaptor and coupler shall permit the transfer of vapour only after initiation of the mating action. 5.2 Performance characteristics The manufacturer shall provide the pressure drop curves for both the vapour collection adaptor an
41、d coupler at the following conditions: flow rate up to 1 500 standard m3/h of air at 20 C (1 500 standard m3/h of air corresponds to the bottom loading of 5 compartments simultaneously each at 150 m3/h flow of substances). 5.3 Pressure ratings The vapour collection adaptor shall be capable of operat
42、ing at the MWP of the transport tank to which it is attached. The vapour collection coupler shall be capable of operating at the MWP of the stationary loading and unloading facility to which it is attached. 5.4 Temperature range Unless otherwise specified, the design temperature range shall be 20 C
43、to + 50 C. Where the vapour collection adaptor and coupler are subjected to more severe conditions, the design temperature range shall be extended to 40 C or + 70 C as applicable. 5.5 Materials of construction The manufacturer shall provide with the equipment a full material specification for those
44、parts that may come into contact with the substances described by Clause 1.
