Any other information on results incl. tables

The weight loss of the test substance at 110°C, 120°C, 130°C and 140°C was lower than the weight loss of reference substance hexachlorobenzene at the same temperatures. Based on this, it was safely concluded that vapour pressure of the test substance is lower than the vapour pressure of this reference substance.

Applicant's summary and conclusion

Conclusions:
In a GLP-compliant study in accordance with EC A.4, OECD 104 and EPA OPPTS 830.7950 using the isothermal thermogravimetric effusion method, the vapour pressure of the substance has been determined as < 9.6E-03 Pa at 25°C and <1.5E-03 Pa at 20°C.
