Application Summary AI generated
GB/T 9273-1988 specifies a test method for evaluating the print-free property of paint films, determining whether a dried coating can resist marking or indentation when subjected to pressure from a standard fabric under controlled conditions. It is applied in the paint and coatings industry for quality control of industrial and decorative finishes, particularly for assessing the hardness and surface resistance of films on metal or wood substrates. This standard is used during product development and batch testing to ensure coatings maintain their appearance and integrity under contact or stacking conditions.
