Conclusions:
In a test conducted according to ASTM E659-14 method, no auto-ignition temperature was observed up to 600°C for Alfalfa, ext.
Executive summary:

A test, conducted according to ASTM E659-14 method, was performed to determine auto-ignition temperature of Alfalfa, ext.

Increments of test sample were admitted to a 500 ml round bottom borosilicate glass flask held within a temperature-controlled enclosure. Samples were injected into the flask over a range of predetermined temperatures and the flask contents were observed in a dark room for 10 minutes following insertion of the sample, or until auto-ignition occurred.

No auto-ignition temperature was observed up to 600°C.

Description of key information

No auto-ignition temperature was observed up to 600°C

Key value for chemical safety assessment
