As a certifying body, RAL-Gütegemeinschaft Kunststoff-Fensterprofilsysteme e.V. (GKFP) awards a quality mark to member companies which submit to the rules of the quality and test requirements in the form of voluntary self-regulation. The aim is compliance with the highest quality requirements in order to ensure the lasting fitness for use of the manufactured products. The members of the association are made up of systems manufacturers, i.e. manufacturers of plastic window profiles and systems, as well as manufacturers of seals, raw materials, film, bonding systems and machinery and contract laminating companies.
For almost 40 years the association has been awarding the RAL quality mark (previously known as the “RAL certification mark”) to products that are subjected to external, neutral quality monitoring and that meet the criteria laid down in the RAL quality guidelines. An initial type test and constant in-house manufacturing control are also required for the purposes of certification. The RAL quality guidelines of the GKFP, the requirements of which go beyond the minimum characteristics specified by the standard, are recognised by the Deutsche Institut für Gütesicherung und Kennzeichnung e.V.
