Applicant's summary and conclusion

Conclusions:
The test material has been determined to have a vapour pressure of 1.8 x 10^-5 Pa at 25ºC using a vapour pressure balance.
Executive summary:

The test procedure was Method 104 specified in the OECD Guidelines for Testing of Chemicals,

 

The vapour pressure was determined using a vapour pressure balance. The temperature of the sample was controlled electronically. The mass and temperature reading were recorded automatically into a computer file.

 

The test material has been determined to have a vapour pressure of 1.8 x 10^-5 Pa at 25ºC using a vapour pressure balance.
