Any other information on results incl. tables

Test 1 : BAM Fall Hammer

Sample Condition:   Performed on sample passing a 0.5 mm sieve

Result : 10kg weight, 40cm drop height Result N, N, N, N, N, N

Where N = No signs of ignition or explosion on impact. When the test assemblies were dismantled there were no signs of decomposition.

 

Test 2: BAM Friction Test

Sample Condition:   Performed on sample passing a 0.5 mm sieve

Result: Weight 9, Position VI, ie 36 kgf load.

Result:     D, D, D, D, D, D

Where D = No sign of ignition or explosion during friction but possible slight decomposition as indicated by dark mark on porcelain plate.

 

Critical load for ignition = >36kgf

 

Test 3: Koenen Steel Tube Test

 

Sample Condition: As received

 

Results:

 

2 mm nozzle "0" "0"  "0"

 

tl/t2 = 45 secs/5 mins; 43 secs/5 mins; 44 secs/5 mins

 

6mm Nozzle:   "0" "0"  "0"

tl/t2 = 39 secs/5 mins; 43 secs/5 mins; 44 secs/5 mins

 

where '0' = tube recovered unchanged

 

tl = time from application of flame to noticeable effect from nozzle.

t2 = time from t1 to recorded event (eg explosion)

 

or as in all trials here to end of trial with no recorded effect.
