- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Deviations:

- Type of method:
- effusion method: vapour pressure balance
- Specific details on test material used for the study:
- - Substance type: Organic
- Physical state: Solid
- Composition of test material, percentage of components: relative proportions components 1, 2 and 3 are 100:60:40 - Temp.:
- 25 °C
- Vapour pressure:
- 0 Pa
- Remarks on result:
- other: It is proposed that the above result be taken as a satisfactory assessment of maximum vapour pressure for the substance.
- Conclusions:
- The vapour pressure was determined to be 1.1 E-05 Pascals at 25 °C.
- Executive summary:
Vapour pressure was determined in accordance with EEC Method A4 and OECD Method 104 using the vapour pressure balance method.
The vapour pressure was determined to be 1.1 E-05 Pascals at 25 °C.
Reference
See attached background material for calculation method, results table and vapour pressure curves.
The curvature evident in the displays of the vapour pressure relationship jeopardises the applicability of a linear extrapolation and it is felt prudent to estimate a maximum room temperature value by imposing a shallow slope of -2000 for the vapour pressure relationship. This yields for the initial data of Run 3 (mass difference 0.3 µg at l15.5°C) a rounded value of Vp(25°C) = 1.1 E-05 Pascals.
It is proposed that the above result be taken as a satisfactory assessment of maximum vapour pressure for the substance.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
