Certification is a process in which materials/products undergo a string of (laboratory) tests in order to verify that the fulfil certain requirements. Sound certification systems should be based on (ideally harmonised) European standards or technical specifications (e.g. by Comité Européen de Normalisation (European organisation for standardization) More, USDA, ASTM, etc.) and be performed by independent third-party laboratories. Successful certification guarantees a high product safety – also on this basis interconnected labels can be awarded that help the consumer to make an informed decision.
