Results and discussion

Vapour pressure
Key result
Temp.:
ca. 25 °C
Vapour pressure:
< 0.001 Pa

Any other information on results incl. tables

Recorded temperatures, mass differences and the resulting calculated values of vapor pressure are shown in the joint document FV36PL.

A total of 5 runs were completed for the main sequence. The values of vapor pressure at 25 °C has

been extrapolated from each graph. (see tables of the FV36PL document).

Applicant's summary and conclusion

Conclusions:
The vapor pressure of the test item has been determined to be less than 9.8 x 10-4 Pa at 25 ºC.
Executive summary:

The vapor pressure of 1574 ACIDE CRIST has been determined to be less than 9.8 x 10-4 Pa at 25 °C, using the vapor pressure balance method, designed to be compatible with Method A.4 Vapour Pressure of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 104 of the OECD Guidelines for Testing of Chemicals, 23 March 2006.
