Materials and methods

Principles of method if other than guideline:
Recommendations on the transport of dangerous goods, manual of tests and criteria, second revised edition, section 33.3
Tests are performed to determine if substances in a 25 mm or 100 mm cube, at test temperatures of 100°C, 120°C or 140°C, undergo spontaneous ignition or dangerous selfheating, which is indicated by a 60°C rise in temperature over the oven temperature within 24 hours.
GLP compliance:
no
