Reference

Reference 1

Endpoint:

vapour pressure

Type of information:

calculation (if not (Q)SAR)

Remarks:

estimated by calculation

Adequacy of study:

key study

Study period:

14.05.2014

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Remarks:

The calculation method is detailed in the following guidelines: - Method A4 of Commission Regulation (EC) No 440/2008 of 30 May 2008, Part A Methods for the determination of physico-chemical properties - Method 104 of the OECD Guidelines for Testing of Chemicals, 23 March 2006

Key result

Temp.:

25 °C

Vapour pressure:

< 0 Pa

Remarks on result:

other: Estimation (calculation)

Transition / decomposition:

yes

Remarks:

decomposition

Transition temp.:

> 700 °C

Conclusions:

In accordance with column 2 of REACH Annex VII, the vapour pressure study (required in section 7.5) does not need to be conducted if the melting point is above 300 °C. The substance's melting point is > 450 °C as determined in the Melting/Freezing Temperature test performed according to test guidelines. The substance has also been found to decompose before melting at temperatures above 700 °C and therefore it was not deemed necessary to perform the actual study. An estimation was, however, thought to be informative for the consideration of human exposure through air. Through calculation the vapour pressure of the substance has been estimated to be less than 1.2 x 10^-9 Pa at 25 °C.

Executive summary:

The vapour pressure of the substance has been calculated to be less than 1.2 x 10^-9 Pa at 25 °C using a procedure detailed in Method A.4 of Commission Regulation (EC) No 440/2008 of 30 May 2008, Part A: Methods for the determination of physico-chemical properties and Method 104 of the OECD Guidelines for Testing of Chemicals, 23 March 2006. The actual study does not need to be conducted.
