Reference

Endpoint:

vapour pressure

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study without detailed documentation

Qualifier:

according to guideline

Guideline:

EU Method A.4 (Vapour Pressure)

GLP compliance:

yes

Type of method:

effusion method: vapour pressure balance

Key result

Temp.:

25 °C

Vapour pressure:

< 0 Pa

Since no weight displacement was observed below 150 °C it can be inferred that the vapour pressure at 298K (25 °C) is lower than the detection limit of the blance i.e. less than 2.6 x 10E-4 Pa.

Conclusions:

For the test substance a vapour pressure of below 2.6E-04 Pa at 25 °C was determined.

Executive summary:

Vapour pressure determination was performed in accordance with EU method A.4 (University of Leeds, ECHA RSS, 2017). The vapour pressure of the test substance is below 2.6E-04 Pa at 25 °C.
