Scope

Main technical content: 1. Coating adhesion: The coating adhesion shall be tested using the 180° bending test method. The diameter of the bending indenter shall comply with the provisions of GB/T 2518 or YB/4761. After the test: No flake-like coating shall be allowed to fall off from the outer surface of the specimen beyond 5mm from the bending edge; coating cracks that do not expose the steel base are allowed, but there shall be no traces of peeling. This standard refines the technical requirements and is more specific than the existing industry standards. 2. Other technical requirements: The remaining technical requirements of this standard are consistent with those of the industry standard YB/T 4761-2019, but with some simplifications. 3. Regarding dimensions, shape, and weight: This section specifies the allowable deviations in thickness and width of the steel strip, sickle bending, unevenness, shape, inner diameter, and weight of the steel strip.
