Investigation of burning behaviour
The determination of the burning behaviour was carried out on the dried substance according to VDI 2263, sheet 1 on a ceramic surface. The sample was applied 2 cm wide and 4 cm long on a ceramic plate. For inflammation, a micro burner with temperatures greater than 1000 °C was used. The reaction of the test substance was assessed visually after the burner was removed. Additionally, the burning behaviour was determined at a higher temperature (100 °C) in a drying oven with sufficient air supply.

The product is grounded and mixed in air. For safety assessment, sample is analyzed on dust screening test and dried to constant mass.
GLP compliance:
no
Specific details on test material used for the study:
Sample: Macrolex Violett B, PZD111405
Sample entry: 2005-10-28
Purity not specified
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
Remarks:
No burning of delivered sample visually observed at room temperature
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
Remarks:
No burning of sample visually observed at a temperature of ca. 100°C

Results:

 Conditions Burning index/ class number  Annotation
 at room temperature, sample as delivered  1 Melting on testing surface
 at room temperature, dried sample  1  Testing in a tray
 at room temperature, with 20 mass-% kieselguhr  5  Testing in a tray
 with a surrounding temperature of ca. 100 °C  1  Testing in a tray
with a surrounding temperature of ca. 100 °C and  with 20 mass-% kieselguhr  5  Testing in a tray

Explanation of combustion factors:

1: No Burning

2: Short ignition and rapid extinction

3: Local burning or glow with minor propagation

4: Annealing without sparks or slow flame-free decomposition

5: Burning away with appearance of flames or sparks spreading

6: Deflagration-like burning or rapid flame-free decomposition

Interpretation of results:
not classified based on GHS criteria
Conclusions:
No burning of Solvent Violet 13 was visually observed neither at room temperature nor at a temperature of ca. 100°C. A burning index of 1 was determined.
Executive summary:

Burning behaviour of Solvent Violet 13 is analyzed according to VDI 2263.

The determination of the burning behaviour was carried out on the dried substance on a ceramic surface. The sample was applied 2 cm wide and 4 cm long on a ceramic plate. For inflammation, a micro burner with temperatures greater than 1000 °C was used. The reaction of the test substance was assessed visually after the burner was removed. Additionally, the burning behaviour was determined at a higher temperature (100 °C) in a drying oven with sufficient air supply.

No burning of Solvent Violet 13 was visually observed neither at room temperature nor at a temperature of ca. 100°C. A burning index of 1 was determined.

Description of key information
