Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
No self-ignition temperature was observed up to the maximum test temperature of 405°C
Key value for chemical safety assessment
Additional information
The self-ignition temperature of Mordant Black 9 was determined according to the European Commission Regulation (EC) No. 440/2008, Method A.16.
8 cm³ (5.3 g) of the test item were placed in an oven at 22°C. The temperature/time curve relating to conditions in the centre of the sample was recorded while the temperature of the oven was increased to 400°C at a rate of 0.5°C/min. The temperature of the oven at which the sample temperature reaches 400°C by self-heating is called the self-ignition temperature for the purpose of this test.
The test item showed an exothermic effect in the temperature range of 235 – 265°C oven temperature with a sharp peak in the test item temperatures of 310°C and subsequent decline to 265°C.
Between oven temperatures of 265°C and 405°C (the final temperature of this test) a broad exothermic effect was observed with a broad peak at approx. 350 °C and the sample temperature remained permanently above the oven temperature.
Due to the low temperature difference between oven and sample at 400°C oven temperature no self-ignition in the sense of the guideline was identified.
No self-ignition temperature was observed up to the maximum test temperature of 405°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
