ISO 15580-2000 Determination of water-based paints and lacquer-based MEQ (milligram equivalent) values in Paints, varnishes and lacquer-based paints is an international standard that specifies a method for determining an important indicator of acid alkalinity in water-based paints and lacquer-based paints - MEQ values (milligram equivalent). The standard uses chemical analysis techniques to measure the content of acids or bases in Coatings to evaluate their impact on the environment and performance. MEQ values are important for the Stability, weathering resistance and curing process of Coatings. The standard describes in detail the test equipment, operation procedures, sample preparation and result calculation methods to ensure the accuracy and repeatability of test results. This standard applies to the quality control and development of Paints, varnishes and water-based paints and lacquers, and can provide important technical support for the performance evaluation and formulation optimization of Coating products.
