Dear Colleagues,
As you know with the advent of the Globally Harmonized Standard, the Safety Data Sheets no longer generally contain actual data on autoignition temperatures but now use the GHS definition of ignites in air for ascribe an H250 code.

Our state fire folks still want to regulate by the autoignition temperature of less than or equal to 130F for pyrophoric substances.

Does anyone know of a good reliable source for this data (in addition to Brethericks)?

Thanks in advance,
