scope:

This Defence Standard specifies the material and performance requirements for a weldable aluminium alloy armour plate, 6 mm and above, of nominal 4% Zinc 2% Magnesium Aluminium alloy in the solution treated and aged condition for the protection of crew and mechanism of armoured fighting vehicles against attack. See Def Stan 95-032 for the supply of this armour material in the form of extrusions or forgings.

It includes a requirement for suppliers to validate their proposed material production route and for the assessment of product quality by ballistic and other tests of pre-production or prototype material. The quality of production shall be assured by quality control, inspection and testing procedures defined in a Process Control Schedule (PCS).

Relevant parts of this Def Stan may be used to control the quality of components made from the alloy plate but whose final shape is achieved by a working process during which the cross-section of the plate is not substantially changed.

For fabrication aspects of this material, reference should be made to Def Stan 08-039. See also the precautionary notes in clauses 8 and 9.

Where the "design end use" of the armour material is primarily for protection against overmatch or shock then the ballistic testing for release purposes may be amended to test for these attributes only. In this case, any purchase orders must be clearly annotated and the armour material clearly identified to reflect the reduced testing and hence limited use of the material.
