ISO 22518 is an international standard on gas chromatograph methods for the determination of solvents in water-diluted Coatings. The standard specifies methods for the determination of solvents in water-diluted Coatings to ensure the mass and adaptability of the Coatings. The standard specifies experimental equipment, experimental procedures and data processing methods. Specifically, the standard requires that Coatings be tested under specific conditions using a Gas Chromatograph and then the content and proportion of solvents are calculated. The standard applies to a wide range of water-diluted Coatings, including Coatings, Adhesives and Plastics, among others. By following this standard, accurate, reliable and comparable solvent measurements can be obtained, ensuring the mass and effectiveness of coatings.
