The ISO 2 2553-9 standard is on the stoving loss test method for Paints and varnish electrodeposition coatings. The standard specifies the measurement of the mass change, or stoving loss, of electrodeposited coatings during the stoving process to evaluate the Stability and Durability of electrodeposited coatings. The standard specifies stoving conditions, sample preparation and Measuring method, etc. Specifically, the standard requires stoving electrodeposition coatings at a specific temperature and time, followed by measurement of the mass change of the coating after stoving, or stoving loss. The standard also specifies the calculation and representation of stoving loss, and the reporting of test results. This standard applies to a wide range of electrodeposition coatings, including automotive parts, home appliances, and metal products. By following this standard, accurate, reliable, and comparable stoving loss test results can be obtained to ensure the mass and performance of electrodeposited coatings.
