The uncertainty of measurement for pressure was about 1 mbar and for temperature, it was about 0.04°C.
The measured vapour pressures were used to regress the coefficients of Antoine's law reported in Table below. They enable to calculate the vapour pressure of the test item at any given temperature provided this temperature falls within the range specified in the same table.

Description of key information
The vapour pressure of the phosphorous acid, triC12-C14 alkyl esters was determined in a GLP-compliant study performed in accordance with EC A.4 method and OECD Guideline No. 104, using the static method.
The vapour pressure at 20°C was 480 Pa +/- 20 Pa.
The vapour pressure at 25°C was 600 Pa +/- 20 Pa.
Key value for chemical safety assessment
- Vapour pressure:
- 480 Pa
- at the temperature of:
- 20 °C
Additional information
The vapour pressure of the phosphorous acid, triC12-C14 alkylesters was investigated in one GLP-compliant study performed in accordance with standard methods, without deviations. The study is considered as reliable (Klimisch 1) and is selected as a key study for the endpoint.
