Rubber and plastics. Polymer dispersions and rubber lattices. Determination of pH1 Scope This International Standard specifies a method for the determination of the pH of polymer dispersions and rubber latices (natural and synthetic) by means of a pH meter equipped with a combined glass and silver reference electrode. The method is also suitable for prevulcanized latex and compounds containing polymer dispersions or rubber latices, including adhesives. NOTE The accuracy of the method decreases at pH values above 11.
