Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of the test item was determined to be 0.02Pa at 25 degrees C and 0.344 Pa at 55 degrees C
- Executive summary:
The vapour pressure of the test substance was determined by a vapour pressure balance method according to guidelines given in EU method A.4. Nine replicate measurements were made between 55 - 65 degrees C. The vapour pressure of the test substance was determined to be:
0.02 Pa at 25 deg. C
0.344 Pa at 55 deg. C
The test substance did not change in appearance under the conditions used in the determination
