Description of key information

A preliminary flammability screening test was performed by applying a flame to a loosely-packed linear pile of TMA for 2 minutes. The pile failed to ignite. According to the UN Recommendations on the Transport of Dangerous Goods, trimellitic anhydride is therefore not classified as readily combustible solid of Division 4.1 and further flammability testing is not required.

Key value for chemical safety assessment
