Generally, there are two types of bending tests: 3-point bend and 4-point bend. The materials that are tested using the flex test method vary from metal
, laminates, particle board, dry wall, ceramic tile to glass. Bending tests vary greatly based on the product being tested.
There are a variety of industry standards which are mostly based on the sample material under test. Bending tests generally involve the measurement of ductility of a sample material. Bending tests may involve taking the sample material to a specific limit and determining the load measurement and its relationship to a load specification (pass/fail). Or, it may involve bending a material until the material experiences a break and determining both the load and deflection required to initiative the break limit.
