Testing on intermediate goods and final goods made of plastics

The objectives of testing specimens taken from finished parts or intermediate products differ significantly from those of molding materials testing. Molding materials testing produces material data that can be compared. This data can be used to compare materials, however calculating the characteristics of a finished product is not possible in most cases.

Therefore, tests on intermediate goods and final goods are performed with two different objectives: determination of functional properties and determination of material properties of a good or product.

Functional product characteristics
For example, stacking strength of packing containers, cable insulation under load, break resistance of a window during a storm, load capacity of a chair, etc.
to Functional product characteristics
Material properties
Determining the material properties of a product. Specimens are taken from a finished product, and are tested after corresponding conditioning according to the same test standards as those that apply to molding materials testing or according to special requirements in the product specification.
to Material properties
Dynstat flexure and impact bending test
DIN 53435
The Dynstat flexure test, the Dynstat impact bending test, and the notched impact bending test to DIN 53435 are used in the characterization of material properties for components made of plastics.
