In each test, test material vented with a flame through the orifice. No explosions occurred and the test tube was not fragmented. Each test was suspended after a total heating period of five minutes.

Applicant's summary and conclusion

Interpretation of results:

GHS criteria not met

Conclusions:

The limiting diameter is less than 2 mm and the substance shows no violent effect on heating under confinement and is considered as not explosive.

Executive summary:

The sensitivity of the substance to the effect of intense heat under high confinement was studied under GLP in accordance with UN Test 2(b), Koenen Test, UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Sixth Edition. The substance was contained in a steel tube, the open end of which was closed by an orifice plate secured to the tube by means of a nut and threaded collar. The tube assembley was located within a test chamber, where it was heated by means of four propane burners. A test was conducted using a plate with an orifice diameter of 1 mm, with three independent runs. During each test, after a time t1 and lasting for a time t2, test material vented with flame through the orifice. No explosions occurred and each test was suspended after a total heating period of five minutes. The tube was recovered unchanged in all runs. Therefore in the absence of a positive result using the 1 mm orifice, no further tests at larger orifice diameters were required. No explosions were observed using the 1 mm orifice and the limiting diameter was <1 mm. In accordance with the criteria of the UN Test 2(b), the outcome of the test is considered to be negative, and the substance shows no violent effect on heating under confinement.
