Reference
Endpoint:
relative density
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Principles of method if other than guideline:
The density data were measured using an Anton Paar Oscillating density meter, model DMA 5000 (serial #241328). The complete OECD guidelines (109 Density of Liquids and Solids) for density of these samples were not followed since the instrument cannot be calibrated in the Analytical lab.
GLP compliance:
no
Type of method:
oscillating densitimeter
Specific details on test material used for the study:
The density data were measured using an Anton Paar Oscillating density meter, model DMA 5000 (serial #241328). The temperature of the cell is regulated internally and measured by two integrated Pt 100 platinum thermometers. Before the measurement of the sample the equipment was calibrated by performing adjustment on both water and air as described in the manual for the DMA 5000 and MID-SOP-17101.01. The validity of the Anton Paar DMA 5000 desnity meter is checked by testing the density of the air and nanopure water and compared to the desnity tables in back of the Anton Paar DMA 5000 Density Meter Instruction Handbook. In addition, toluene was also run as a standard to ensure the accuracy of the temperature of the DMA 5000. The Pt 100 thermometers, which read the temperature of the sample cell, are inaccessible to the operator of the instrument. The toluene runs provide an indirect test of accuracy of temperature measurement and is located in the study folder. All testing is done in replicate of three with the average of the three results being calculated. The complete OECD guidelines (109 Density of Liquids and Solids) for desnity of these samples were not followed since the instrument cannot be calibrated in the Analytical lab. Adjustments and standard checks are done to make sure instrument is performing correctly. Calibrations can only be done by the instrument manufacturer which is only planned when the standard checks are not within 1% of the expected value.
