| WLN-CA.W.80.1 | Determination of the saturation index (SI index)) | in accordance with NEN 6533 |
| Principle: | The temperature, acidity, electrical conductivity, calcium content and hydrogen carbonate content of water samples are determined, after which the equilibrium pH8 is calculated using a formula.The saturation index (SI index) is the difference between the measured pH and the equilibrium pHs.The saturation index is a measure of the lime aggressiveness of water, a positive SI-index indicates that the water is lime-depositing, a negative SI-index indicates that the water is lime-dissolving. | |
| Determination: | Saturation-index | |
