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: The data was created by testing using GLP principles
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Deviations:
- no
- Principles of method if other than guideline:
- The vapour pressure was determined using a vapour pressure balance system with measurements being made at several temperatures and linear regression analysis used to calculate the vapour pressure at 25°C. Tesing was conducted using a method designed to be compatible with Method A4 Vapour Pressure of Commission Regulation (EC) No 440/2208 of 30 May 2008 and Method 104 specified in the OECD Guidelines for Testing of Chemicals, 27 July 1995.
- GLP compliance:
- yes
- Type of method:
- effusion method: vapour pressure balance
- Temp.:
- 25 °C
- Vapour pressure:
- < 0 Pa
- Conclusions:
- The Vapor Pressure of D.E.R. 331 was measured and found to be 4.6 x 10-8 Pa at 25°C.
