Results and discussion

Flammable solids

Key result

Test procedure:

burning rate test: preliminary screening test

Remarks on result:

substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

Applicant's summary and conclusion

Interpretation of results:

GHS criteria not met

Conclusions:

The study was performed according to UN N.1 with acceptable restrictions (no GLP) and therefore reliability of Klimisch 2 has been assigned. No ignition or burning through of the test item was observed during the preliminary screening test and hence, a full test is not necessary.

Executive summary:

The test was performed as stipulated in UN test procedure ‘Recommendations on the Transport of Dangerous Goods - Manual of Tests and Criteria’ (UN-MTC), Part III, sub-section 33.2.1.4.1, Test N.1 ‘Test method for readily combustible solids’ (no GLP).

The substance was formed into a powder train about 250 mm long by 20 mm wide by 10 mm high on a non-combustible, non-porous and low heat-conducting base plate. 30 – 40 mm beyond the 100 mm timing zone, 1 mL of a wetting solution was added to the pile. A hot flame from a gas burner was applied to one end of the powder train until the powder ignites or for a maximum of 2 minutes. A preliminary screening test was performed to determine if propagation by burning with flame or smoldering occurs without wetted zone. If propagation over 200 mm of the train occurs within a specified time then a full test programme to determine the burning rate was carried out. The substance in its delivery state was measured. A burner flame was used as ignition source. The test substance melted when approached by the ignition flame. The substance did not burn up. No further testing was required.

‘1,8-Dichlorantrachinon' is classified as a not readily combustible solid when tested according to UN-MTC Procedure N.1.
