Thermal test results

   T1 (seconds)  T2 (seconds)  Observations
 6 mm Orifice      
 Test 1  12  300  Burned with a yellow flame; tube recovered intact
 Test 2  11  300  Burned with a yellow flame; tube recovered intact
 Test 3  12  300  Burned with a yellow flame; tube recovered intact
2 mm orifice     
 Test 1  11  300  Burned with a yellow flame; tube recovered intact
 Test 2  12  300  Burned with a yellow flame; tube recovered intact
 Test 3  10  300  Burned with a yellow flame; tube recovered intact

 

where

TI = time from start of test to flame from nozzle

T2 = time from start oftest to explosion, or end of test (300 seconds)

Shock test results

 Replicate  1  2  3  4  5  6
 Result  N  N  N  N  N  N

where N = no evidence of explosion. In three of the tests (1,3 and 5), a small puff of smoke was observed and a brown residue noted after testing, indicating decomposition. In the other cases, there was no sign of decomposition, although the die could not be disassembled to check for decomposition after test 4.

Friction test results

 Replicate  1  2  3  4  5  6
 Result  N  N  N  N  N  N

where N=no evidence of ignition or explosion. Dark mark on plate indicative of decomposition (5 out of 6 tests), but no evidence of decomposition in test 2.

Conclusions:
ATBS was concluded not to be explosive.
