97% toluene-4-sulphonohydrazed; 3% Hydrated castor oil
Key result
sensitiveness to friction: friction load (N)
Remarks on result:
not sensitive to friction using a friction load of 360 N
Key result
thermal sensitivity - Koenen test: limiting diameter (mm)
Remarks on result:
negative (not further specified)
t1=6s; t2=25s: no explosion t1=8s; t2=24s: no explosion t1=7s; t2=22s: no explosion
Key result
sensitiveness to impact: impact energy (J)
Remarks on result:
not sensitive to impact using an impact energy of 40 J
1 test: decomposes in traces with odor development; 5 tests: no reaction. Overall: no reaction
Interpretation of results:
GHS criteria not met
The substance is not explosive.
Executive summary:

With a diameter of the hole of 2.0 mm in the nozzle plate, no explosions were found in all three experiments. In all three experiments, the pods remained unchanged

In all 6 experiments no explosions were observed at a strike energy of 40J. In one experiment, traces of traces of decomposition with odor development were found in places.

At a friction pin load of 360N, no reaction was observed in any of the 6 experiments.

The substance is not explosive.

Description of key information

The study does not need to be conducted since the Calculated Oxygen Balance is < 200.

Key value for chemical safety assessment

non explosive

Additional information

Calculated Oxygen Balance=146 = 1600/186.23*(2*7+10/2-2).

Justification for classification or non-classification

The substance does not need to be classified as explosive, because TSH is classified as a self-reactive substance Type D.
