Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1986-05-05 - 1986-05-05
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- no guideline available
- Principles of method if other than guideline:
- Iron is determined by atomic absorption. Tests are conducted at 25 °C. Gas volume used: 1483 L. The detection limit of the method is 0.05 ppm.
- GLP compliance:
- no
- Type of method:
- other: Iron is detected by atomic absorption in a gas volume
- Key result
- Temp.:
- 25 °C
- Vapour pressure:
- < 0 Pa
- Conclusions:
- No iron was found in the traps. With a detection limit of the method of 0.05 ppm, the vapour pressure is calculated as < 116.37E-6 Pa at 25 °C
- Executive summary:
Vapour pressure of ferbam is determined via Iron-determination by atomic absorption. Tests are conducted at 25 °C. Gas volume used: 1483 L. The detection limit of the method is 0.05 ppm. No iron was found in the traps. With a detection limit of the method of 0.05 ppm, the vapour pressure is calculated as < 116.37E-6 Pa at 25 °C
Reference
Test:
Gas volume used: 1483 L
Volume of water used in trap 1: 77.8 g
Iron amount: < 77.8 x 0.05E-6 g
Ferbam amount: < 77.8 x 0.05E-6 x (416.5 / 55.8) g = <29.01E-6
Vapor pressure: < ((29.01E-6 x 8.3142 x 298) / (1,483 x 416.5)) Pa = < 116.37E-6 Pa = < 8.6E-7 Torr.
Description of key information

Additional information
Supporting Information 1: Perkow, 1992
authoritative publication: Ferbam has a vapour pressure of appoximatelly 0 Pa.
Supporting Information 2: Tomlin, 1997
authoritative publication: Ferbam has a vapour pressure of appoximatelly 0 Pa.
Supporting Information 3: EpiSuite calculation, 2017
accepted calculation method: The vapour pressure of Ferbam is calculated with different methods: Antoine method, Mackay method and modiefied Grain method. All calculations have in common that the vapor pressure is approximately equal to zero.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
