Vapour pressure
Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 23 January - 22 April, 2015
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: The study was conducted according to an internationally recognised method, and under GLP. No deviation was reported. Test substance is adequately specified with isomer purity. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Deviations:
- no
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- UK GLP compliance programme (inspected on 05 February 2014 / signed on 07 October 2015)
- Type of method:
- effusion method: vapour pressure balance
- Key result
- Temp.:
- 25 °C
- Vapour pressure:
- 0.07 Pa
- Remarks on result:
- other: interpolated
- Conclusions:
- Low volatility (based on volatility bands criteria for occupational exposure (Chesar / ECETOC TRA), < 500 Pa).
- Executive summary:
The vapour pressure of the test substance was measured under GLP according to OECD 104 / EU A4 guideline by an effusion method using a vapour pressure balance. Two definitive runs were performed between temperatures of 21 and 60 °C. Vapour pressure at 25 °C was interpolated from the regressions.
The runs yielded a mean vapour pressure value at 25 ºC of 0.071 Pa.
The vapour pressure of the test item has been determined to be 0.07 Pa at 25 °C.

- 25 °C
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EU method, is available. It is considered as a key study. The result is retained as key data.
