ASTM D6902-04 (2023) specifies a method for the measurement of formaldehyde release during melamine formaldehyde-based Coating curing under laboratory conditions. This standard is suitable for evaluating the formaldehyde content released by Coating during the curing stage. Through specific testing devices and procedures, the formaldehyde release can be accurately determined, thus providing a scientific basis for the environmental performance of Coating products. The method has a detection range of 500μg/g to 22000μg/g and is widely used in quality control and product development in the Coating industry to ensure that the product meets environmental requirements.
