Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From July 25 to 31, 2014
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. No deviation was reported. The test substance is adequately characterised. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Version / remarks:
- 2006
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Version / remarks:
- Regulation (EC) N°440/2008
- Deviations:
- no
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- UK GLP compliance programme (inspected on March 12 to 14, 2014 / signed on May 12, 2014)
- Type of method:
- gas saturation method
- Key result
- Temp.:
- 25 °C
- Vapour pressure:
- 3.2 Pa
- 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, gas saturation method.
Determinations were conducted at 25, 35 and 45 °C, with three flow rates per temperature. Mass of evaporated test item was quantified by GC. Vapor pressure at 25 °C was interpolated from the regression.
The vapor pressure of the test item has been determined to be 3.2 Pa at 25 °C.

Validation
The linearity of the detector response with respect to concentration was assessed over the concentration range of 1.07 to 1.07 X 103 mg/L (n = 7). The results were satisfactory with a correlation coefficient of 1.000 being obtained.
The concentrations in the sample solutions from traps 1 ranged between 42.2 and 189 mg/L, and therefore, were within the calibration range. For traps 2 (0.05 —0.14 mg/L), inaccuracy in the determination is considered negligible as this collected fraction represents less than 0.5% of the total amount.
Description of key information
Low volatility.
Key value for chemical safety assessment
- Vapour pressure:
- 3.2 Pa
- at the temperature of:
- 25 °C
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. Therefore, it is considered as a key study, and the result is retained as key data for purpose of CSA.
