Key result

Remarks on result:

other: no spontaneous ignition occured at 140°C

No spontaneous ignition occurred and no exothermic effect of the test item was observed at 140°C. It demonstrated that 1,3-Bis (4-hydroxy benzoyl) benzene

is “not a self-heating substance”. According to the UN guideline, no further testing is required.

After the experiment, the consistency of the sample was unchanged, therefore it was concluded that no reaction and/or decomposition of the test item was observed.

Conclusions:

The test item is not classified as "self-heating" according to GHS criteria, based on the negative results obtained at 140°C using a 10 cm sample cube.

Executive summary:

The self-heating temperature of the test item was determined (Brekelmans, 2018) according to a recognised guideline and in compliance with GLP. No deviation from the guideline was observed during the test.

A sample of the test item was maintained at 140°C in a sample cube of 10 cm inside an oven during 24 hours.

No spontaneous ignition occurred and no exothermic effect of the test item was observed at 140°C. According to the guideline no further test was required and the test item is not classified as "self-heating" according to GHS criteria.

Description of key information

The self-heating properties of test item were detemined in a key study of Klimisch validity 1 performed according to recognised guidelines and in compliance with GLP (Brekelmans, 2018).

No deviation from the guideline was observed in the study.

Additional information

Based on the experimental results obtained in the key study (Brekelmans, 2018), the test item is not classified for self-heating hazard according to UN GHS criteria.
