GB/T 15825.5 is a Chinese national standard for a bending test used to evaluate the bend formability of sheet metal. To match this to your program, talk with our team.
What GB/T 15825.5 Covers
It assesses how well sheet metal can be bent without cracking, a formability property important for stamping and forming operations, within the GB/T sheet formability series.
How the Test Is Run
A sheet specimen is bent around formers of decreasing radius until cracking appears, and the minimum bend radius or bendability rating characterizes the formability.
Why It Matters
Bend formability governs which parts can be formed from a sheet grade; a controlled bend fixture with a range of former radii is needed.
