Applicant's summary and conclusion

Conclusions:
Using the Static Technique, the vapour pressure of GR-85-2517 at 20°C:

p(20°C) = 14.1 +/- 0.3 Pa = (1.06 +/- 0.02) x 10^-1 mmHg
Executive summary:

The determination of the vapour pressure of GR-85 -2517 was performed in accordance with the following guidelines:

European Economic Community (EEC), EEC directive 92/69 EEC, Part A, Methods for the determination of physico-chemical properties, A.4 "Vapour pressure", EEC Publication No. L383, December 1992.

Organisation for Economic Co-operation and Development (OECD), OECD guidelines for Testing chemicals, Guideline No. 104: "Vapour pressure curve", July 27, 1995.

Using the Static Technique, the vapour pressure of GR-85-2517 at 20°C:

p(20°C) = 14.1 +/- 0.3 Pa = (1.06 +/- 0.02) x 10^-1 mmHg
