Qualifier:
according to guideline
Guideline:
UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
Deviations:
no
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Other quality assurance:
ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
Key result
Test procedure:
burning time over 250 mm for metal powders or metal alloys
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

A preliminary screening test was performed to determine if propagation by burning with flame or smoldering occurs without wetted zone. Solvent Violet 36 was formed into a powder train about 250 mm long by about 20 mm wide by about 10 mm high on a non-combustible, nonporous and low heat-conducting base plate. If propagation over 200 mm of the train occurs within a specified time then the full test program to determine the burning rate is carried out. Solvent violet 36 melted on approach of the flame. No ignition and no burning of Solvent Violet 36 was observed. Therefore, the performance of the full test was not necessary.

Interpretation of results:
GHS criteria not met
Conclusions:
Solvent Violet 36 is a non-flammable solid according to EU method A.10 and did not deliver indications of pyrophoric properties during the realization of other tests. Therefore the determination according to UN-MTC Procedure N.2 is not necessary. The chemical structure of the substance contains no metals or metalloids. Testing according to UN-MTC*) procedure N.5 is not necessary with reference to Appendix 6, chapter 5.3.. Solvent violet 36 is not self-heating according to UN-N.4.
Executive summary:

a.) Flammability:Solvent Violet 36 is a non-flammable solid according to EU method A.10.

b.) Pyrophoric properties:Solvent Violet 36 did not deliver indications of pyrophoric properties during the realization of other tests. The determination according to UN-MTC Procedure N.2 is not necessary.

c.) Contact with water:The chemical structure of the substance contains no metals or metalloids. Testing according to UN-MTC procedure N.5 is not necessary with reference to Appendix 6, chapter 5.3..

d.) Self-heating substances:Solvent Violet 36 is not self-heating according to UN-N.4.

Result:
negative outcome (no effect observed)

In the temperature/time diagram was no exothermic reaction. At the end of the test the wire-mesh basket was empty.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
Solvent violet 36 is not self-heating according to UN-N.4.
Executive summary:

The test was performed as stipulated in UN-MTC procedure N.4. As a screening test the Grewer oven test (VDI guideline 2263, part 1, 1990) was made. Solvent Violet 36 under test was placed in a wire basket with 8 ml volume in an tube shaped oven at room temperature. The oven was heated up at a rate of 0.5 K/min up to 420 °C. The temperature of the center of the sample and the temperature of an inert reference sample, which was placed in another tube of the same oven, were recorded. Both samples were vented with air at a rate of 20 L/h. In the temperature/time diagram was no exothermic reaction. At the end of the test the wire-mesh basket was empty. With respect to appendix 6, chapter 5.2.2 of UNMTC there were no additional tests necessary. Solvent Violet 36 is not self-heating according to UN-N.4.

Endpoint:
substances / mixtures which in contact with water emit flammable gases
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied
Endpoint:
pyrophoric solids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied
