Description of key information

This test can be waived because tetrahydromethylphthalic anhydride is a liquid under normal environmental conditions. For liquids, the key measure of the flammability is the flash point (see section 4.11).
Experience in handling and use show that tetrahydromethylphthalic anhydride is not flammable in contact with water and has no pyrophoric properties. Tests on these parameters have thus not to be conducted.
Flash point was determined as 164 degree C at 1003 hPa measured by the closed cup method.

Key value for chemical safety assessment

non flammable

Additional information

Justification for classification or non-classification

Based on a flash point of ca. 164 degree C and a boiling point of 295.3 degree C tetrahydromethylphthalic anhydride is not classified regarding flammability according to 67/548/EEC and Annex VI of 2008/1272/EC (CLP, GHS).
