AS 5602 pdf download – Refined petroleum products—Vehicle bottom loading and vapour recovery
This Standard provides requirements 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.
This 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.
