Executive summary:

Maximum ignition temperature for a powder layer was measured according to SOP-08, using a controlled hot plate and Pico-log data acquisition system, based on IEC Standard 1241 -2 -1, Part 2. Two screening tests were performed. No ignition or exotherm was observed up to temperatures of 400C.
