Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Vapour pressure
Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- In accordance with OECD Guidelines for The Testing of Chemicals, 104, March 23 2006, Vapor pressure is measured using a modified static method. The modification being that a direct reading MKS Baritron Capacitance Manometer Model 628B was substituted for the mercury manometer in the method. Water bath temperature was measured using a NIST traceable digital thermometer readable to 0.1°C (Certificate # 14-648-12) c
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Deviations:
- yes
- Remarks:
- Vapor pressure is measured using a modified static method. The modification being that a direct reading MKS Baritron Capacitance Manometer Model 628B was substituted for the mercury manometer in the method.
- Principles of method if other than guideline:
- In accordance with OECD Guidelines for The Testing of Chemicals, 104, March 23 2006, Vapor pressure is measured using a modified static method. The modification being that a direct reading MKS Baritron Capacitance Manometer Model 628B was substituted for the mercury manometer in the method. Water bath temperature was measured using a NIST traceable digital thermometer readable to 0.1°C (Certificate # 14-648-12) c
- GLP compliance:
- not specified
- Type of method:
- static method
- Remarks:
- Modified static method: a direct reading MKS Baritron Capacitance Manometer Model 628B was substituted for the mercury manometer in the method.
- Temp.:

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.
