1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

GLP compliance:

yes (incl. QA statement)

Key result

Remarks on result:

no self ignition observed under the test conditions

Temperature data

The temperatures which were measured in the experiment are presented in the following table. Many values were recorded, here only the values at every 60 minutes (until the oven had reached the chosen temperature) are presented.

Table 1: Presentation of temperatures versus time

Time in min	Temperature (test item) in °C	Temperature (oven) in °C
5	21.1	20.6
60	34.8	46.6
120	66.1	81.9
180	98.3	117.8
240	131.5	153.5
300	167.4	189.1
360	204.3	224.3
420	242.8	259.3
480	281.2	293.7
540	315.2	326.0
600	354.5	361.1
660	391.8	393.7
670	400.0	399.8

After the end of the test, the test item was completely black and carbonized.

No increase in the temperature of the sample in comparison to that of the oven could be detected. No signs of ignition could be observed.

Conclusions:

No increase in the temperature of the sample in comparison to that of the oven could be detected. No signs of ignition could be observed. The test item was considered as not auto-flammable under the test conditions. After the end of the test, the test item was completely black and carbonized.

Executive summary:

A study was performed according to Regulation (EC) No 440/2008, Method A.16 in order to determine the relative self-ignition temperature of the test product with the help of an ZPA-3 oven. The test item was placed into a stainless steel cube and should be heated from room temperature to an oven temperature of 400 °C (heating rate 0.57 K/min). No increase in the temperature of the sample in comparison to that of the oven could be detected. After the end of the test, the test item was completely black and carbonized.

No signs of ignition could be observed. The test item was considered as not auto-flammable under the test conditions.

Description of key information

The test item was considered as not auto-flammable under the test conditions.
