Description of key information

Auto-flammability (1,1,1,3,3,3-hexamethyldisilazane): 331°C at 1013 hPa (ASTM E659-78)

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
331 °C

Additional information

Several auto-flammability data are available for the substance. The results are considered reliable where (i) they have been conducted according to international or national standard methods (even where no further information about the study is available) or (ii) the data is taken from a reliable handbook. A measured auto-flammability value of 331°C was determined for the substance using a relevant National Standard Method. The result is considered to be reliable and selected as key study. Other reliable sources gave auto-flammability values of 325 - 380°C for the substance. The key study has been selected because it contains the most details about the test methods. In other secondary sources to which reliability could not be assigned, an auto-flammability of 325°C was reported for the substance.
