MODUK DEF STAN 95-24 PDF

This standard 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 160 mm (medium hardness) and 3 mm through 100 mm (high hardness) for the protection of crew and mechanism of armoured fighting vehicles against attack. 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 Defence Standard 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. 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 for the first time, the designations used in this standard for Class 1 and Class 2 armour have been interchanged from MVEE 816 and preceding standards. Class 1 armour from MVEE 816 is now Class 2 in Def Stan 95-24 and Class 2 armour from MVEE 816 is now Class 1 in Def Stan 95-24.

USERS MUST CONFIRM THAT THEY ARE USING THE CORRECT CLASS OF ARMOUR.
