Thermal sensitivity (Effect of flame)

Type of orifice Plate	Replication No.	Dry Run Test - Weight of Test Item (g)			Observation
		First run (a)	Second run (b)	Total amount (a+b)
6.0mm	Rl	4.5391	7.6722	12.2113	No explosion occurred
	R2	4.5013	7.6613	12.1626	No explosion occurred
	R3	4.4918	7.6128	12.1046	No explosion occurred
2.0mm	Rl	4.4486	7.6037	12.0523	No explosion occurred
	R2	4.5011	7.5908	12.0919	No explosion occurred
	R3	4.4986	7.5991	12.0977	No explosion occurred

Heating rate calibration: The heating rate graph between temperature time was found to belinear.

The results of thermal sensitivity (effect of flame) test with FAT 41047/A TE showed that after heating the test item with flame for 5 minutes using 6.0 and 2.0 mm diameter orifice plates, there was no fragmentation of steel tubes containing test item and hence, the test item was considered as non-explosive.

Mechanical sensitivity (Shock) test

Weight of dropping mass	Replication No.	Volume of test item	Height of dropping mass	Observation
10 kg	Rl	40 mm^3	0.4 m	No bursting into flame or sparks
	R2	40mm^3	0.4 m	No bursting into flame or sparks
	R3	40 mm^3	0.4 m	No bursting into flame or sparks
	R4	40mm^3	0.4 m	No bursting into flame or sparks
	RS	40mm^3	0.4 m	No bursting into flame or sparks
	R6	40 mm^3	0.4 m	No bursting into flame or sparks

The apparatus evaluated by using the reference chemical 1,3-dinitrobenzene.Itwas observed that the reference chemical was explosively decomposed by the formation of hard mass.

The results of mechanical sensitivity (shock) test with FAT 41047/A TE showed that there was no bursting into flame or sparks when conducted the experiment with 10 kg mass from 0.4 meter height in six replications and hence, further experiment with lower weight (5 kg) and lower height (0.15 meter) was not performed. Therefore, the test item was considered as non-explosive when subjected to shock test.

Mechanical sensitivity-Friction test

Amount of loading	Replication No.	Volume of Sample	Observation
360N	R1	10 mm^3	No explosion flame, sparks and crepitation
	R2	10mm^3	No explosion flame, sparks and crepitation
	R3	10mm^3	No explosion flame, sparks and crepitation
	R4	10mm^3	No explosion flame, sparks and crepitation
	R5	10mm^3	No explosion flame, sparks and crepitation
	R6	10mm^3	No explosion flame, sparks and crepitation

The apparatus evaluated using the reference chemical 1,3-dinitrobenzene.Itwas observed that the reference chemical was explosively decomposed by the formation of hard mass.

 

The results of mechanical sensitivity (friction) test with FAT 41047/A TE showed that there was no explosion, flame, sparks and crepitation when test was performed with 360 N (5 kg+ 4.9 kg) and hence, further experiment with 120 N was not performed. The test item was considered as non-explosive when subjected to friction test.

Interpretation of results:

GHS criteria not met

Conclusions:

FAT 41047/A TE is a non­explosive when subjected to flame, shock and friction.

Executive summary:

The determination of explosive properties of FAT 41047/A TE was carried out in accordance with EEC method A.14 guideline.

The thermal sensitivity (effect of flame) test after heating the test item with flame showed that the FAT 41047/A TE is a non-explosive.

The mechanical sensitivity (shock) test with FAT 41047/A TE showed that there was no bursting into flame or sparks when assessed with 10 kg mass from 0.4-meter height in six replications.

The mechanical sensitivity (friction) test with FAT 41047/A TE showed that there was no explosion, flame, sparks and crepitation when test was performed with 360 N (5 kg+ 4.9) kg.
