These are descriptions rather than measured values, so they are kept out of the table above and quoted here with the source that reported them.

Fire and explosion

The primary hazard is blast where the entire load can explode instaneously and not from flying projectiles and fragments. Under prolonged exposure to fire or heat they can explode. /Pentaerythrite tetranitrate; Pentaerythrite tetranitrate, wetted/
