Systematic and Comprehensive Quality Specification and Verification for Furniture Industry—DIN 919, DIN 68100, VDI 3414, VDI 3415
摘要
Mostly in the furniture industry the quality approach is anecdotical. A systematic convergence of specifications for claims of functions and design is missing. A system has now been drafted or agreed in accordance with the aforementioned German standards, which follows the Geometrical Product Specification (GPS, ISO 8015) system and offers new possibilities for coding on technical drawings, as well as in the downstream chain of standards for measuring, testing and process capability analysis. DIN 919-2 as a new drafted German standard for technical drawing in wood industry is opening up the whole tool set of GPS coding elements. DIN 68100 is adding a geometrical tolerance system including swelling or shrinkage. DIN68100-2 will propose statistical tolerancing to convolute variances in geometry caused e.g. by production with distributions in moisture content or shrinkage coefficients. VDI 3414 is offering specifications and corresponding verifications for attributive quality characteristics of wooden surfaces including a naming and coding system. Finally VDI 3415-2 is referring to measuring and production capability analysis esp. for the wood industry and related research. As far as possible the German standardization activities will be presented in the paper. The selected use case will be the edge banding and profile wrapping where the new guideline VDI 3412 will assist the practitioners and scientists concerning specification, verification but as well in trouble shooting.
