Materials and methods

Test guideline
Qualifier:
according to guideline
Guideline:
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
Deviations:
no
Principles of method if other than guideline:
PRINCIPLE OF THE TEST:
A volume of about 8 cm3 of the solid test item is placed in an oven at room temperature. The temperature / time curve (see Figure No. 1 in the attached illustration) relating to conditions in the
centre of the sample is recorded while the temperature of the oven increases to 400 °C (at least) at a rate of about 0.5 °C/min.
The temperature of the oven at which the sample temperature reaches 400 °C by self heating is called the self-ignition temperature for the purpose of this test.
GLP compliance:
yes (incl. QA statement)
