Reference
Endpoint:
density, other
Remarks:
Liquid density
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Qualifier:
no guideline followed
Principles of method if other than guideline:
The liquid density was determined using standard density floats which have a reported accuracy of ±0.2kg·m-3.
Method is described in "Basu, R. S., Wilson, D. P., 1989 Thermophysical properties of 1,1,1,2-tetrafluoroethane (R-134a)", and is based on ASTM D1505.
GLP compliance:
not specified
Type of method:
buoyancy method

Type:
other: Saturated liquid density
Density:
1 100 kg/m³
Temp.:
22.69 °C
