scope:

This Defence Standard specifies requirements for a grade of expanded polystyrene granules suitable for the production of natural or coloured expanded polystyrene mouldings and blocks, of apparent density 16kg/m³ or greater. The mouldings are primarily used as spacers and packing pieces in the transport and packaging of munitions.

The material may be suitable for certain applications where compatibility with explosives is a requirement. However, compatibility with all explosives in all environments has not been established and Design Authorities should seek advice on particular applications. Further information may be obtained from Defence Standard 13-102: Testing of Materials which are Required to be Compatible with Explosives.
