Variable Sample Mass Test with the MKIII Ballistic Mortar

6 Variable sample mass test with the MKIII ballistic mortar 5 5 G  

Propagation of deflagration Detonatable substances cannot be tested because the apparatus will be broken. 

The MKIII ballistic mortar is the same mortar used in the test with variable initiators. 

The sample vessel in the variable sample mass test is made of a thin polyethylene tube with a diameter of 23 mm. The bottom is closed by adhesive tape. The initiating explosive with a No.6 electric detonator and 0.6 g of PETN is inserted into the inner tube used in the variable initiator test. A sample vessel assembly is shown in Fig.3.138.
