ISO 19396-1:2017 specifies a method for laboratory measurement of the pH value of polymer dispersions and coating materials using pH electrodes with a glass membrane. ISO 19396‑2 specifies a method for measuring the pH value using pH electrodes with ion-sensitive field-effect transistor (ISFET) technology.

Overview

ISO 19396-1:2017 - "Paints and varnishes - Determination of pH value - Part 1: pH electrodes with glass membrane" specifies a standardized laboratory method to measure the pH of polymer dispersions and coating materials using pH electrodes with a glass membrane. The standard covers required apparatus, electrode types, sampling, calibration, measurement procedure, evaluation, precision and test reporting. It is part of the ISO 19396 series (Part 2 covers ISFET electrodes).

Key topics and technical requirements

Scope and principle: Laboratory measurement of pH for aqueous paints, varnishes and polymer dispersions using a glass‑membrane potentiometric measuring chain (combination electrode + reference).

Apparatus: pH meter (reading accuracy 0.01 pH), pH electrode with integrated temperature sensor recommended, buffer solutions, containers, cleaning and storage solutions, stirrers and thermostats.

pH electrode types: Solid electrolyte, liquid‑electrolyte refillable (annular gap, capillary, protruding ceramic diaphragms) and low‑maintenance designs - guidance provided in Annex A.

Calibration and performance: Calibration with at least two buffer solutions to determine practical slope and zero point; meter must show pH proportional voltage (mV) and temperature; temperature compensation is required for buffer behavior.

Procedure and sampling: Defined test conditions, sample preparation and number of determinations to ensure representativeness and reproducibility.

Evaluation and precision: Includes repeatability and reproducibility considerations based on interlaboratory tests; Annex B describes determination of precision.

Reporting: Required elements for a complete test report to support traceability and quality control.

Practical applications

Quality control of coating production (pH stability, batch-to-batch consistency)

R&D and formulation development for paints, varnishes and polymer dispersions

Shelf‑life and durability testing where pH affects product performance

Regulatory and compliance testing where documented, standardized pH methods are required

Calibration and validation of laboratory equipment and measurement procedures
