Results
140 °C, 100 mm cube sample
a) temperature profile of the test using a 100 mm cube sample (weighed mass: 546.5 g) at an oven temperature of 140 °C: The temperature in the centre of the sample did not exceed the oven temperature within a storage time of 48 hours.
b) the test item after the test at 140 °C in the 100 mm cube sample:
Since the temperature increase is below the threshold of 60 °C within 24 hours the result of the test is negative.
Due to the negative result in the 100 mm cube sample at an oven temperature of 140 °C further tests do not have to be performed.
Applicant's summary and conclusion
- Conclusions:
- The test item is not classified as self-heating substance according to CLP Regulation EC 1272/2008 Annex 1: 2.11.
- Executive summary:
The Bowes-Cameron-Cagetest in the 1 L wire basket at 140 °C showed no self-heating of the test item 2,4-Dihydroxybenzoic acid within 24 hours. Due to this result further tests were not necessary.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
