bottom loading and vapour recovery, which has been withdrawn.the purpose of this standard is to ensure that all tank vehicles fitted for bottom loading and vapour recovery are compatible and can be safely loaded at fill stands equipped for bottom loading, including those equipped for vapour recovery. this standard also covers unloading into receiving tanks.this standard is intended to apply in conjunction with, but not take precedence over, regulatory requirements issued bystatutory authorities havingjurisdiction over environmental matters and the storage and handling of dangerous goods.individual companies may have requirements and procedures that are additional to those set out in this standard.the standard is downloaded from standard sharingstatements expressed in mandatory

and recommendations for use by the refined petroleum industry in terms of vapour recovery equipment for vehicles equipped for bottom loading and for vehicle fill stands designed for bottom loading and having vapour recovery facilities. it covers the design and operation of vapour recovery equipment on vehicles and fill stands.the purpose of this standard is to ensure that all tank vehicles fitted for bottom loading and vapour recovery are compatible and can be safely loaded at fill stands equipped for bottom loading, including those equipped for vapour recovery. it also covers unloading into receiving tanks.it is intended to be used in conjunction with regulations relating to environmental matters and the storage and handling of dangerous goods.1.2 applicationthis standard applies to the following: (a)product connections for loading. (b)vapour connections.(c) overfill protection systems. (d)interlocks on the fill stand.(e) requirements when unloading.(f) requirements when vapour recovery is not required.this standard covers those elements that need to be standardized in order to achieve safe operation.1.3 referenced documentsthe following documents are referred to in this standard: as2809road tank vehicles for dangerous goods2809.1part 1: general requirements for all road tank vehicles2809.2part 2: road tank vehicles for flammable liquidsus department of defensemil-c-27487coupling halves, quick-disconnect, cam-locking type1.4 definitions and abbreviationsfor the purposes of this standard, the following definitions apply: standards a.au1.4.1 adaptorthe male part of a connection between a pipe and a hose.1.4.2 adg codethe australian dangerous goods code, published by the national transport commission.1.4.3 aipthe australian institute of petroleum.1.4.4 apithe american petroleum institute.1.4.5 approvedapproved by the purchaser.1.4.6 couplerthe female part of a connection between a pipe and a hose.1.4.7 shallindicates that a statement is mandatory.1.4.8 shouldindicates a recommendation.1.4.9 switch loadingthe loading of a low vapour pressure product into a compartment that previously contained a high vapour pressure product.1.4.10 vrvapour recovery.1.4.11 vtvapour transfer.1.5 road tank vehiclesvehicles shall comply with as 2809, parts 1 and 2.s e c t i o n2p r o d u c tc o n n e c t i o n sf o r l o a d i n g2.1 scope of sectionthis section sets out requirements for adaptors and couplers used when loading product.2.2 adaptor specificationadaptors fitted to vehicles shall be self-sealing 100 mm api industry standard adaptors as shown in figure 2.1.valve head sealing surface travel fr om sealing surface the standard is downloaded from standard sharingsealing surface figure 2.1 typical 100 mm standard tank vehicle adaptor2.3 coupler specificationsthe following requirements apply to couplers:(a) the coupler fitted to the fill stand shall be a self-sealing 100 mm api industry standard coupler to mate with the industry adaptor.(b) the loader coupler shall accommodate adaptors mounted at any slope between 0 and25 downwards from horizontal.(c) the coupler adaptor shall be interlocked so that it cannot be opened or closed unless it is connected.2.4 location of adaptorsadaptors shall be located on the tank vehicle generally as illustrated in figure 2.2.notes:1figure 2.2(a) illustrates the connection envelope of fittings, not including handles.2figure 2.2(b) illustrates the angle of connections (dry break to loading arm).3figure 2.2(c) illustrates the recommended distances from underrun protection to ground and dry break fittings (these distances can be minimized if a gate facility is operated to ensure unimpeded access).1280 overall 2000 max. overall product connections at 300 min. and 350 max. centres 100 to 800 *100 to 400 *overfill pr otection socket permanent vapour hose 350 min. gr ound clearance * connection gr ound level * p o s i ti o n w i th i n e n ve l o p e s o n o i n t e r f e r e n c e o c c u r s w h e n hose is in use * to c o m p l y w i th a s 2 8 0 9note: envelope of outer surfaces of fittings does not include handles.(a) truck connection location envelopesfor r oad tank vehicles for all other tankers 380 max. 100 min. 300 max. 100 min. centre of valve head outer face of adaptor (refer to fig. 2.1) flexible joint if r equir ed 100 hose 15 m a x.
