Scope

This International Standard specifies a gravimetric method for determining potassium in potassium chloride for industrial use, that is to say in a product whose minimum KCl content is approximately 95% {m/m). This limit, conventionally expressed in K or K20, corresponds to approximately 50% (m/m) or 60% (m/m) respectively.
