experimental study

Adequacy of study:

key study

Study period:

1995

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: Valid method

Principles of method if other than guideline:

Grewer test according to company guideline and hot storage test

Relative self-ignition temperature:

>= 240 °C

Remarks on result:

other:

Remarks:

at atm. press. of ca.1013.0 hPa

The sample shows self-ignition in the Grewer oven starting at 240 °C.

The hot storage test at 140 °C reveals warming of the sample to max. 141 °C.

time to temperature equalisation: 8 h 14 min

time from temp. equalisation to max. temp.: 59 min

total time to max. temp.: 9 h 13 min

Conclusions:

The test substance shows self-ignition at 240 °C in the Grewer screening test. Hot storage test at 140 °C in the 1 L wire basket results in a max. sample temp. of 141 °C.

Executive summary:

Self-heating of the test substance was determined by a screening test in the Grewer oven and by a hot storage test. The test substance shows self-ignition at 240 °C in the Grewer screeningtest. The hot storage test at 140 °C in the 1 L wire basket results in a max. sample temp. of 141 °C. The test substance is not self-heating at 140 °C.
