Specific details on test material used for the study:
- lot/batch No.of test material: 0000000413
Key result
Water solubility:
110 g/L
Conc. based on:
test mat.
Temp.:
20 °C
pH:
11
Remarks on result:
other: Mean value of 6 samples
Details on results:
The concentrations of the test item measured in at least the two last vessels do not differ by more than +/- 15 % and there is no trend in the values, thus the test is satisfactory.
The relative standard deviation (repeatability) of the concentrations in all six samples was smaller than 15 % and the three duplicate sets of samples showed no tendency of increasing concentration values. Thus the test was satisfactory.
