Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

The measured lowest ignition temperatures of the main test are < 300°C and do not differ by more than 10°C, thus the test is satisfactory.

The auto-ignition temperature is defined as the lowest temperature of all single results of the main test, but rounded down to multiples of 5°C.

Lowest ignition temperatures [°C]:

  • Test 1: 200
  • Test 2: 203
  • Test 3: 200

Auto-igintion temperature: 200 °C

Conclusions:
Auto-ignition temperature (A.15 / DIN 51 794; GLP): 200 °C at 1014 hPa
Executive summary:

The auto-ignition temperature of the test item was determined according to EU test method A.15 [Directive 92/69/EEC, Official Journal L 383 A 1992] and DIN 51 794:

Auto-ignition temperature: (1014 hPa): 200 °C

The test(s) used to generate this report was(were) carried out in compliance with the principles of Good Laboratory Practice (GLP) in accordance with the currently valid German Chemical Substance Act (Chemikaliengesetz – ChemG), the underlying Commission Directive 2004/10/EC of 11 February 2004 and the relevant OECD decision of the council on 26 November 1997 and that the results fully reflect those found in the study.

Description of key information

Auto ignition temperature (EU method A.15, DIN 51794; GLP; AQura, 2010): 200 °C at 1014 mbar

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
200 °C

Additional information

The auto-ignition temperature of the test item was determined according to EU test method A.15 [Directive 92/69/EEC, Official Journal L 383 A 1992] and DIN 51 794 compliant with GLP:

Auto-ignition temperature: (1014 hPa): 200 °C (AQURA, 2010).

This result was confirmed by a non-GLP supporting study (Givaudan, 2015) resulting in the same temperature (200 °C).
