Testing of sensitivity

Torpedo friction test. A test of sensitiveness to impact and friction (see p. 70). 

Elliot, M. A. et al., Kept. Invest. No. 4169, Washington, US Bin. Mines, 1948 Tests of sensitivity to initiation by heat, impact, shock or ignition sources were made on mixtures of a variety of absorbent materials containing a stoicheiometric amount of 40-70% perchloric acid. Wood meal with 70% acid ignited at 155°C and a mixture of coal and 60% acid which did not ignite below 200° C ignited at 90° C when metallic iron was added. Many of the mixtures were more sensitive and dangerous than common explosives. 

The OECD, US-EPA, and EU have no adopted test guidelines for in vitro testing of sensitization. 

The Gap Test, sometimes called Barrier Test or Booster Test, was first suggested by H. Muraour in MAF 12, 559(1933), but the first systematic study of the phenomenon was done by G. Herzberg R. Walker, Nature 161, 647(19-48). Since that time many expls labs both in the US and abroad have adopted and standardized it as a practical test of sensitivity. The apparatus used by... 

NOTE Neither a Series 1 type (a) propagation of detonation test nor a Series 2 type (a) test of sensitivity to detonative shock is required if the exothermic decomposition energy of organic materials is less than 800 J/g. 

NOTE 2 Two systems of dilutions in liquid media for testing of sensitivity to antibiotics are presented in tabular form, followed by disc sen.-sitivity and special liquid concentrations not fitting in either of the two dilution series.]...
