Reference

Endpoint:

vapour pressure

Type of information:

experimental study

Adequacy of study:

key study

Study period:

1997-11-03 to 1997-12-15

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study with acceptable restrictions

Qualifier:

according to guideline

Guideline:

EU Method A.4 (Vapour Pressure)

Version / remarks:

Directive 92/69/EEC, A.4.

Deviations:

not specified

GLP compliance:

yes

Type of method:

effusion method: vapour pressure balance

Temp.:

20 °C

Vapour pressure:

< 0 hPa

Remarks on result:

other: temperature range between 20 and 150 °C

Precautionary a Different Scanning Calorimetry was done. The test substance shows an endothermic effect beginning at 160°C and an exothermic decomposition after.

In the temperature range between 19.8 °C and 150.4 °C no increase in weight and therefore no vapour pressure of the test substance was registered with the balance.

Conclusions:

A vapour pressure value of lower than 0.00001 hPa was determined between 20 and 150 °C in a reliable study conducted according to EU method A.4.

Executive summary:

The vapour pressure of the test item was determined according to EU method A.4. and is 0.00001 hPa in the temperature range between 20 and 150 °C. No increase in weight was registered on the balance within this temperature range and therefore no increase in vapour pressure could be detected.

Description of key information

The test item has a vapour pressure of lower than 0.00001 hPa between 20 and 150 °C.

Key value for chemical safety assessment

Vapour pressure:

0 hPa
