Specifies design and construction requirements for tanks together with certain of their appurtenances, but does not deal with their installation or with road, rail, or marine tanks, or with fuel tanks for vehicles. It does not apply to the storage of materials that are not liquid at normal temperatures and pressures. It provides for six categories of tank, ranging from those in Category 1 of up to 1200 L capacity and for above ground use principally for the storage of oil fuel in domestic premises, to those in Category 6 of any capacity and of a size and type that is usually erected on site. The specification requirements may be applied to tanks constructed of other than steel. Typical acceptable joints are illustrated.

This Standard specifies requirements for the design and construction of tanks for the storage of flammable and combustible liquids, together with certain accessories. It does not deal with their installation, nor does it deal with road, rail, or marine tankers, or with fuel tanks for vehicles. It is applicable only to the storage of materials that are liquid at normal temperatures and pressures.NOTES:1. This Standard is basically oriented towards cylindrical tanks of commercial grade low carbon steel for petroleum fuel storage, this being the most common application for tank storage, but it also provides for stainless steel tanks. Glass-fibre reinforced plastics are recognized alternative materials, but are dealt with in other Standards, notably BS 4994 and AS 2634. It is recognized that the storage of other types of liquid, or the use of other materials of construction, may render part or all of this Standard inappropriate; any such substitutions should be the subject of specific approval.2. Attention is drawn to Appendix A, which sets out details of particular information that the purchaser needs to supply in order that the manufacturer can complete the tank.
