The new DIN SPEC 35255 defines standardized <\/strong>quality requirements for fiber composite <\/strong>plastic processes. Fraunhofer IFAM initiated <\/strong>this important milestone for the application <\/strong>by forming a consortium, which was registered <\/strong>and supported by DIN. DIN SPEC 35255 <\/strong>is now available for free download in German <\/strong>and English.<\/strong><\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The following applies to the demanding manufacturing, maintenance and repair processes of FRP components: In accordance with the Product Safety Act (PSA), the \u201cstate of the art\u201d must be applied in order to be able to use a material, a product made from it or a process safely. A product may only be brought to the market \u201cif it does not endanger the safety and health of persons when used as intended or in a foreseeable manner\u201d.<\/p>

If this verification cannot be provided purely non-destructively and with one hundred per cent certainty on a process and product-specific basis, ISO 9001 defines this as a so-called \u201cspecial process\u201d. In order to fulfil the \u201cstate of the art\u201d, errors must be avoided from the beginning of the product development phase through production, maintenance and repair to the end of the product.<\/p>

Special case composites <\/strong><\/p>

Fibre composite technology thus represents another of many \u201cspecial processes\u201d, as are welding and adhesive bonding, for example. For these, the \u201estate of the art\u201c is avoiding possible
process and product defects through a consistent quality management system (QMS), e.g. in accordance with ISO 9001. However, ISO 9001 only defines the QM framework conditions and requires technology-specific concretization.<\/p>

Basic works <\/strong><\/p>

The new DIN SPEC 35255 does this for the fibre composite technology by specifying, comparable to the corresponding welding and adhesive bonding standards, an existing QMS and the ISO 9001 core idea of error prevention, thus helping user companies to work (still more) safely with fibre composite technology.<\/p>

Application and benefits <\/strong><\/p>

DIN SPEC 35255 defines both the requirements for the quality-compliant development and design of fibre composite components and the general organisational, contractual and manufacturing principles for development, production, maintenance and repair across all cross-industry sectors. It contains the three core elements familiar from the welding and adhesive bonding standards:<\/p>
