| 520 | |a"Three synthetic samples and two filtered natural samples were sent to eighteen participating laboratories for the determination of specific conductance, pH, colour and filterable residue. The pH of the natural samples was determined with a standard deviation of 0.3-0.5 pH units, which is distinctly higher than the value of about 0.1 pH units which is found for buffered synthetic samples. The precision of the colour measurements was fair, as would be expected for the visual method used. Generally good precision was obtained for specific conductance using the conductivity meter. Results for residue were surprisingly poor on the synthetic samples but satisfactory on the natural samples. It appeared from the nature of the results and from the participants' comments that weighing difficulties were an important problem in residue determination"--Summary, page v. |
