It is a long tradition of product testing and assessment in the construction field. Standards form the basis for certification.
Requirements for construction products were laid down in European Standards and EU-Directives refer to these standards, which are the consensus for the commitment og requirements for construction products.
Characteristics of german construction products are traditionally better than the European Standard, but is it enough that manufacturers alone know this? The user may appreciate teh high quality level of german products in the course of many years of use without problems. It is decisive for a successful marketing that the user realises the later satisfaction in advance and that he find the way to high quality products in the labyrith at the market. The DIN certification marks of DIN CERTCO are reliable signs for special products.
