Room temperature: 20 to 21°C

Atmospheric pressure: 100.81 to 102.29 kPa

Conclusions:

The test material has been determined not to have an auto ignition temperature below 400°C.

Executive summary:

The auto-ignition temperature was determined by heating aliquots of the test material in a flask and observing for any ignition. Testing was conducted using Method A15 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).

 

The test flask was heated in a flask heater. Aliquots of test material (tested as received) were dropped into the flask which was observed for signs of ignition over a 300 second period. This procedure was repeated, varying the sample size, as necessary, until the lowest temperature at which ignition, if any, occurred within 300 seconds of insertion, was determined.

 

The test material has been determined not to have an auto ignition temperature below 400 °C.
