The test substance was tested for determination of vapour pressure according to the guidelines OECD 104, EPA Subdivision D 63-9 and EU Method A.4. The vapour pressure of the test substance was determined by the vapour pressure balance method based on a micro-balance with a sensitivity of approximately 0.1 µg. The temperature of the sample was controlled electronically over the range ambient to 250°C. The mass readings and temperature were recorded directly onto a 2 channel chart recorder. The vapour pressure balance is designed in a way that on opening the slide across the orifice in the temperature controlled evaporation furnace, the escaping vapour jet was directed at the scale pan. The vapour pressure was determined directly from the pressure on the scale pan by measuring the difference of mass readings when the slide across the orifice was open and closed and also when efficient condensation occurs from the rate of the latter onto the pan. The vapour pressure of the sample was measured at several temperatures to yield vapour pressure curves for subsequent extrapolation to give 298.15K values. The vapour pressure of the test substance was determined to be 1.2 x 10e-5 Pa at 20°C and 2.0 x 10e-5 Pa at 25°C.
