scope:

This INTERIM Defence Standard specifies requirements for vulcanized butyl rubber suitable for the tubing of baby viper hose (also known as 'Charge, land mine clearing, No.1 ').

The test requirements are based on test pieces cut from the extruded vulcanized tubing, but this INTERIM Standard defines only the composition and physical test requirements for the material. Dimensional and other requirements to verify suitability of the tubing are defined in the drawing and/or specification for the finished hose.

NOTE: The tubing is normally produced in long pieces (up to 110ft) and is 5/8 inch in diameter and 3/32 inch in thickness of walls.

The designation 'Type OX' indicates that the materiar 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, Defence Research Agency (Military Division), Fort Halstead, Sevenoaks, Kent TN 14 7BP.

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