scope:

This Defence Standard specifies requirements for polyethylene terephthalate, chopped fibre, type QX for use in explosives.

The designation 'Type QX' indicates that the material is suitable for certain applications where a high degree of compatibility with explosives is a requirement. However, its compatibility with all explosives in all environments has not been established. Design Authorities requiring advice on particular applications should in the first instance contact the Directorate of Standardization, Stan 5, Kentigern House, 65 Brown Street, Glasgow, G2 SEX for guidance.

Attention is drawn to Defence Standard 13-102, Testing of Materials which are Required to be Compatible with Explosives.
