ISO 4315: Determination of Alkalinity

The ISO 4315 standard includes the test method for the determination of alkalis in the form of carbonates, bicarbonates, alkali hydroxides or free organic bases such as triethanolamine. The ISO 4315 test method is performed to determine alkalinity in surfactants. Not suitable for products containing soap.

Test principle; It is based on titration of the sample with a standard volumetric hydrochloric acid solution in the presence of methyl orange or bromophenol blue as an indicator.
