- Reference substance (Bis(2 -ethylhexyl)-phthalat) was used.

- Formula used for the calculation:

Tm = -25 °C

Antoine equation: p = 10 exp(A - B / (T+C))

- Interpolation range: Tm < T < 125.6 °C

A = -1.7476

B = 93.9615

C = -16.8200

R = 0.99668

Explanation:

p = vapour pressure in hPa

T = temperature in °C

Tm = melting point in °C

R = correlation coefficient

Conclusions:

Using the vapour pressure balance method the vapour pressure of the test item was determined to be <1E-5 hPa at 20 °C, <1E-5 hPa at 25 °C and 2.63E-5 hPa at 50 °C.

Executive summary:

Using the vapour pressure balance method the vapour pressure of the test item was assessed in accordance with EU method A.4. Using the Antoine equation and regression analysis the vapour pressure was determined to be <1E-5 hPa at 20 °C, <1E-5 hPa at 25 °C and 2.63E-5 hPa at 50 °C.

Additional information

Using the vapour pressure balance method the vapour pressure of the test item was assessed in accordance with EU method A.4. Using the Antoine equation and regression analysis the vapour pressure was determined to be <1E-5 hPa at 20 °C, <1E-5 hPa at 25 °C and 2.63E-5 hPa at 50 °C.

For chemical safety assessment a vapour pressure of 0.00001 hPa at 20 °C was used.
