- EPA OPPTS 830.7950 (Vapor Pressure)
- Deviations:
- no
- Principles of method if other than guideline:
- Not relevant
- GLP compliance:
- no
- Type of method:
- spinning rotor
- Temp.:
- 20 °C
- Vapour pressure:
- 0.001 Pa
- Remarks on result:
- other: standard deviation: 2.04 x 10^-4 Pa
- Conclusions:
- The vapor pressure of Phosflex 61B is 1.08 x 10^-3 Pa at 20 degrees Celsius.
- Executive summary:
The vapor pressure of Phosflex 61B was determined using the spinning rotor gauge method according to OECD guideline 104 / OPPTS 830.7950 under GLP. The vapor pressure of Phosflex 61B was found to be 1.08 x 10^-3 Pa at 20 degrees Celsius.
Reference
The offset value was 9.6645 x 10 -8 s-1 at 20°C. This value was based on the average deceleration rate measured with an empty sample chamber. The mean measured background vapor pressure of the system by the SRG method was 4.24 x 10 -5 Pa at 20°C.
The mean measured vapor pressure of hexachlorobenzene by the SRG method was 1.14 x 10-3Pa at 20°C. The vapor pressures were consistent with published values.
Description of key information
The vapour pressure of Phosflex 61B was determined to be 0.00108 Pa at 20°C.
Key value for chemical safety assessment
- Vapour pressure:
- 0.001 Pa
- at the temperature of:
- 20 °C
Additional information
In a key study, the vapor pressure of Phosflex 61B was determined using the spinning rotor gauge method according to OECD guideline 104 / OPPTS 830.7950 under GLP. The vapor pressure of Phosflex 61B was found to be 0.00108 Pa at 20°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
