Type of information:
experimental study
Adequacy of study:
key study
Study period:
23rd December 1994 to 31st March 1995
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Study conducted in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of relevant results.
according to guideline
EU Method A.2 (Boiling Temperature)
GLP compliance:
yes (incl. QA statement)
Date of inspection: 31st January 1994 Date of signature: 16th March 1994
Type of method:
method according to Siwoloboff
Specific details on test material used for the study:
Container: metal canister
Storage conditions: Room temperature until 1st December 1994, thereafter room temperature in the dark.
Key result
Boiling pt.:
278 °C
Atm. press.:
> 100.6 - < 103.6 kPa

Mean of two measurements

The boiling temperature of ST 02 C 94 was determined to be 278 +/- 2 °C, at atmospheric pressure (ranging from 100.6 to 103.6 kPa).
Executive summary:

Method: The experimental procedure used complied with that specified in EU Method A2.

Procedure: The determination was carried out using the Siwoloboff method.

Results: The boiling temperature of ST 02 C 94 was determined to be 278 +/- 2 °C at atmospheric pressure (ranging from 100.6 to 103.6 kPa).

Description of key information

Experimental normal boiling point.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
278 °C

Additional information

An experimental study on boiling point measurement of the test material, was conducted under GLP, and considered as fully reliable. Therefore the result is considered as key data.
