- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- 92/69/EEC
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Swiss GLP compliance programme (inspected on September 09 and 30, 2002/ signed on December 2002)
- Type of method:
- method according to Siwoloboff
- Specific details on test material used for the study:
- - Physical state: liquid
- Storage condition of test material: refrigerator (0-10°C) under nitrogen - Atm. press.:
- 98 kPa
- Decomposition:
- yes
- Decomp. temp.:
- ca. 294 °C
- Executive summary:
The boiling point of the test substance was determined under GLP according to OECD103/EU A2 guideline, Siwoloboff (capillary) method.
Two main runs were performed, and the lower temperature was retained.
The test material has been determined to decompose from approximately 294 °C, prior to boiling at a pressure of 98.0 kPa.
Reference
Individual measurements: (1) 567 K, (2) 572 K.
Accuracy not specified.
Description of key information
Decomposition before boiling, from ca 294°C. (experimental)
Key value for chemical safety assessment
Additional information
A reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. Despite minor restrictions on accuracy, it is considered as a key study. As decomposition was observed, no key value can be retained.
