标准范围

将不同浓度的待测物质溶液与已知钙硬度不同的硬水溶液混合。将溶液置于规定条件下，观察其外观，即清澈度、乳白色、浑浊度或沉淀。该方法适用于在20°C下可溶于水的表面活性剂。它可以扩展到在大约50°C下可溶的表面活性剂。

Solutions of the substance to be tested in differing concentrations are mixed with hard water solutions of differing known calcium hardness. After leaving the solutions to stand in specified conditions their appearance, i.e. clearness, opalescence, cloudiness or precipitation is observed. The method is applicable to surface active agents soluble in water at 20 °C. It can be extended to those which are soluble at approximately 50 °C.
