Materials and methods

Test guideline
Qualifier:
equivalent or similar to guideline
Guideline:
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
Principles of method if other than guideline:
The relative self-ignition temperature was determined according to “Annex A.16” in EC Regulation No.440/ 2008. A certain volume of the sample is placed in an oven and is heated at a constant but slow rate. The temperatures of the oven and in the center of the sample are continuously recorded at the same time. The temperature of the oven at which the sample temperature reaches 400°C by self-heating is called the self-ignition temperature.
GLP compliance:
no
Other quality assurance:
ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
