scope:

This Standard relates to two type QX natural rubber-resin adhesives suitable for use where temperatures within the range -20 ºC to + 60 ºC may be encountered.

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, compatibility with all explosives in all environments has not been established, and Design Authorities should seek advice on particular applications from the Director, Propellants, Explosives and Rocket Motor Establishment, Waltham Abbey, Essex, EN9 1BP.

The adhesive, natural rubber-resin, type QX, No 2 shall not be used in stores containing double-base propellants because of the solvent action of 1, 1, 1-trichloroethane on ingredients (especially nitroglycerine) of propellant compositions.
