MODUK DEF STAN 95-024 PDF

This Def Stan specifies the material and performance requirements for five classes of rolled steel armour in the form of hardened and tempered homogeneous plate of nominal thickness 3 mm through to 160 mm (medium hardness) and 3 mm through to 100 mm (high hardness) for the protection of crew and mechanisms of armoured fighting vehicles against attack. The standard 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 within a Process Control Schedule (PCS).

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

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.

NOTE: In order to provide a coherent classification, including the high hardness armours listed in this standard, the designations used in this standard for Class 1 and Class 2 armour have been interchanged from Military Vehicles and Engineering Establishment (MVEE) 816 and preceding standards. Class 1 armour from MVEE 816 is now Class 2 in Def Stan 95-024 and Class 2 armour from MVEE 816 is now Class 1 in Def Stan 95-024.
