(1) Inspection Method:
1. Tensile Test Method: Commonly used standards for tensile testing include GB/T 228-87, JIS Z2201, JIS Z2241, ASTM A370, GOST 1497, BS 18, and DIN 50145. These methods are widely applied to assess the mechanical properties of materials under tension. 2. Bending Test Method: Standard procedures for bending tests include GB/T 232-88, JIS Z2204, JIS Z2248, ASTM E290, GOST 14019, and DIN 50111. These tests evaluate the material’s ability to withstand bending without fracturing.
(2) Performance Index: When evaluating the performance of angle steel, the main inspection items are tensile and bending tests. Key indicators include yield strength, tensile strength, elongation, and the ability to pass the bending test. These parameters help determine the material's overall quality and suitability for specific applications.
In addition to these standard tests, other factors such as surface finish, dimensional accuracy, and corrosion resistance may also be considered depending on the intended use of the angle steel. It is important to follow the appropriate testing procedures to ensure that the material meets the required specifications and safety standards.
