BS EN 13081:2008+A1:2012EN 13081:2008+A1:2012 (E) 5 Introduction The vapour collection adaptor and coupler are part of the 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
26、and coupler establish a vapour tight path between the transport tank and the stationary loading and unloading facilities. BS EN 13081:2008+A1:2012EN 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 th
27、e transport tank and the stationary loading and unloading facilities. This European Standard specifies the performance requirements and the critical 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
28、 and unloading facilities. It also specifies the tests necessary to verify the compliance of the equipment with this standard. The equipment specified 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 p
29、ressure not exceeding 110 kPa, at 50 C and 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.

34、 highest effective pressure allowed in the tank during filling (maximum filling pressure allowed) b) highest effective pressure allowed in the tank during discharge (maximum discharge pressure allowed) c) effective gauge pressure to which the tank is subjected by its contents (including such extrane
35、ous gases as it may contain) at the maximum working temperature BS EN 13081:2008+A1:2012EN 13081:2008+A1:2012 (E) 7 !3.2 probe device used to displace the obturator (poppet) of the adaptor“ 4 Function The vapour collection adaptor and coupler shall provide the following: a quick action vapour tight
36、mechanical connection between the transport tank and the stationary loading and unloading facilities for the transfer of vapour; vapour tightness when not connected. The vapour collection adaptor may be capable of accepting interlock actuators and similar devices, see Annex C. The vapour collection
37、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 of liquid. 5 Design characteristics 5.1 General The vapour collection adaptor and coupler shall permit the transfer of vapour only after initiation of t
