Vapour pressure

Link to relevant study record(s)

Reference

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.
