Materials and methods

Test guideline

Test guideline 1

Qualifier:

according to guideline

Guideline:

EU Method A.16 (Relative Self-Ignition Temperature for Solids)

Deviations:

yes

Remarks:

The heating rate of the oven over the complete heating range was 0.57 K/min. instead of 0.5 K/min. This was considered as uncritical as the deviation is minimal and no self- heating over 170 °C could be observed during the test.

Test guideline 2

Qualifier:

according to guideline

Guideline:

other: SOP 118 009 42 "Bestimmung der relativen Selbstentzündungstemperatur fur feste Prüfgegenstande nach EU", edition 7, valid from 15.Oct.2014

GLP compliance:

yes (incl. QA statement)

Applicant's summary and conclusion

Conclusions:

No increase in the temperature of the sample in comparison to that of the oven could be detected; also no signs of ignition could be observed.
The test item V516690 is considered as not auto-flammable up to 170 °C under the test conditions. After cooling down the test item was unchanged.
