Materials and methods

Test guidelineopen allclose all
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.
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.
