Flexure tests/bending test are generally used to determine the flexural modulus or flexural strength of a material. The material is laid horizontally over two points of contact (lower support span) and then a force is applied to the top of the material through either one or two points of contact (upper loading span) until the sample fails. The maximum recorded force is the flexural strength of that particular sample.

Generally, there are two types of flexural test/bending tests: 3-point bend and 4-point bend. The materials that are tested using the flex test method vary from metal, plastic, wood, 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. Flexure 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.
