We at BÜFA Composite Systems are proud to have been part of the interdisciplinary team involved in the development of the new DIN SPEC 35255 "Quality requirements for composite processes". This milestone in standardization underlines the importance of high-quality fiber composite plastic processes for diverse industrial sectors.

Norms and standards are an effective instrument for quality assurance and of particular importance for technology transfer. Experiences from e.g. welding and adhesive technology impressively show that thanks to uniform standards and practical quality management systems, confidence and market acceptance of a wide range of technologies are considerably increased.
Quality standards are also decisive for fiber composite plastic processes. Fiber-reinforced plastics or composites are widely used due to their lightweight construction potential, especially in the automotive, rail vehicle, shipbuilding, aerospace, and wind energy sectors. The manufacturing process is demanding. A standardized process for quality assurance within the manufacturing and maintenance of composite components is therefore crucial.
A first step towards increasing composite quality was initiated by Fraunhofer IFAM by forming a consortium, which was registered and supported by DIN. The joint consortium, consisting of industry partners, certification bodies, and research institutions, has set itself the goal of developing a set of rules for the "Quality requirements for fiber reinforced plastics processes" along the complete composites process chain.
The consortium has now achieved a breakthrough with the new DIN SPEC 35255. The new DIN SPEC defines standardized quality requirements for fiber composite plastic processes. Analogous to the established welding and bonding standards, DIN SPEC 35255 also contains the three core elements: the classification of composite components according to safety requirements, the requirements for personnel competence, and the verification of real stress compared to maximum stressability.
