The pH value of aqueous products is essential for the properties and storage stability of a product. This part of DIN 55659 (DIN 55659-2) specifies a test method for determining the pH value of aqueous polymer dispersions and coating materials by ISFET (ion sensitive field effect transistor) technology. Part 1 specifies a test method for determining the pH value of coating materials using pH electrodes with glass membrane.
