The test item did not change in appearance under the test conditions. No statistical analysis were performed because the balance readings were too low and variable for a line of best fit to have any meaning. Instead it was considered more appropriate to impose a regression slope on a chosen data point to provide an estimate of the maximum value for the vapour pressure at 25 °C. Run 10 was chosen because the sample had been under the vaccum for the longest period prior to this run and so degassing would have been the most complete. The readings at 140 °C (413.15 K) was chosen because this is the data point which gives the highest estimated vapour pressure at any given temperature when a slpe of -1500 K is imposed upon it. The value of -1500 K is an in-house value and is the shallowest slope observed whilst determining the vapour pressure on a wide range of samples using the vapour pressure balance method. Extrapolation to 25 °C gave a vapour pressure of 2.214E-4 Pa which has been taken as a maximum for this material. 

Conclusions:

The vapour pressure of FAT 36038/J is less than 0.0023 Pa at 25 °C.

Executive summary:

The vapour pressure of FAT 36038/J was evaluated in a study conducted according to the EU Method A.4 and OECD Guideline 104. The vapour pressure balance method was used for this purpose. Based on the findings of the study, it was concluded that the vapour pressure of FAT 36038/J is less than 0.0023 Pa at 25 °C.
