Application Summary AI generated
This standard specifies a method for determining the flexibility of paint films by bending a coated metal panel over a series of mandrels of decreasing diameter. It is applied in the coatings industry to evaluate the ability of a paint or varnish film to withstand cracking or detachment when the substrate is deformed. The test is critical for quality control of paints used on flexible surfaces, such as automotive body panels, metal packaging, or coil coatings.
