Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Specific details on test material used for the study:
SOURCE OF TEST MATERIAL
- Batch No.of test material: AN-0400-111
- Expiration date of the lot/batch: 01 January 2019
- Purity: 100% UVCB

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Approximately -20 °C under nitrogen in the dark

TREATMENT OF TEST MATERIAL PRIOR TO TESTING
- Treatment of test material prior to testing: tested as received
Key result
Auto-ignition temperature:
254 °C
Atm. press.:
>= 101 - <= 101.8 kPa
Remarks on result:
other: ± 5°C
Conclusions:
The auto-ignition of the test material was determined to be 254 ± 5 °C at an atmospheric pressure of 101.8 pKa.
Executive summary:

The auto-ignition of the test material, terpenes and terpenoids, turpentine oil, α-pinene fraction, dimers was determined using a procedure compatible with Method A.15 Auto-Ignition Temperature (liquids and gases) of Commission Regulation (EC) No. 440/2008 of 30 May 2008.

The test flask was heated in a flask heater and then aliquots of the test material (tested as received) were injected into the flask using a syringe and the flask was observed for signs of igniton over a 300 second period. The process was repeated, varying the sample size as necessary, until it was possible to determine the lowest temperature at which ignition, if any, occurred within 300 seconds of insertion. The flask was flushed with air between sample insertions, when clean flasks were not used.

Based on the evaluation of data, the test material was determined to have an auto-ignition temperature of 254 ± 5°C at an atmospheric pressure of 101.0 -101.8 pKa.
