scope:

This specification defines the requirements for a type of rosin suitable for use in the manufacture of sealing compositions etc which may be in contact with explosives.

The designation 'Type QX' indicates that the material is of a quality suitable for application where a high degree of compatibility with explosives is a requirement. However, its compatibility with all explosives in all environments has not been established and Design Authorities should seek advice on particular applications from the Director, Royal Armament Research and Development Establishment, Waltham Abbey.
