Modified Influence (Propagation) Test. Gawthrop (Ref 1) and others used a modified gap test to determine the relative ability of a shielded donor charge to transfer detonation over an air gap to an acceptor charge. Clark (Ref 2) also used this method for the determination of the gap in the transmission of detonation from a small charge (0.5 to 2g) of HE to a cartridge of 40% straight dynamite... 

Gap Tes/(Propagation Test or Sympathetic Detonation Test). In order to ascertain the relative ability of the disturbance sent out by the explosion of a shielded detonator charged with pentryi as the base charge to transfer deton over an air gap to a receiving charge of an expIosive(such as dynamite), Clark used the same method as he described fa DDNP in IEC 25,668(1933)... 

The propagation test may also be conducted similarly to the pin method described by Cook(Ref 6)...

An SD-DSC test is highly useful for screening the danger of explosion of self-reactive substances. When the result of an SD-DSC test lies in the border zone between the explosive and nonexplosive regions, however, a more reliable standard propagational test should be conducted to determine which quality is accurate.

The authors discussed in the following such detonation-propagation tests as the 50/60 steel tube test under sand, the 50/60 steel tube test under water and the variable initiator test using the ballistic mortar or ballistic pendulum. If one or more of these tests is used, the detonation-propagation of self-reactive substances can be evaluated. The limitations of these methods is listed in Table 3.40.
