Scope and application

This programme is applicable for the approval of material manufacturers of:

— Aluminium alloy castings

as referred in the Society's rules and standards. For a description of general requirements, conditions and procedures related to the approval, please refer to DNV-CP-0346 which shall be applied in combination with this programme.

Approval is given for the manufacture of main types of cast aluminium alloys, e.g.:

— unalloyed aluminium, 99%Al minimum

— AlCu alloys

— AlSiCu, AlSiMg and AlSiCuMg alloys

— AlSi alloys

— AlMg alloys

— AlZn alloys

— AlSn alloys.

The product(s) used for approval testing (see Sec.3) will place limitations on the range of approval. The approval will be limited to the casting method, maximum casting weight, maximum section/wall thickness and heat treatment/delivery condition. Approval testing of castings will cover approval of ingots and semis, but not vice versa.

Where aluminium alloy castings are repaired by welding, or two or more items are joined by welding to form a composite item, the manufacturer's welding shop shall either be approved for welding in accordance with this programme, or be approved as welding workshop. For welding workshop approval, see DNV-CP-0352.
