The certification body whose certificatenregister this directory’s Dutch fire-door and passive-protection files were built from — every KOMO attest and CE certificate traced back to a scheme SKG-IKOB operates. It is accredited by the Raad voor Accreditatie as a product certification body to NEN-EN-ISO/IEC 17065 (C003), as a management system certification body to 17021 (C063) and as an inspection body to 17020 (I332), and is designated by the Ministry of the Interior and Kingdom Relations as notified body 0960 for CE marking under the Construction Products Regulation. It now runs its own testing facilities at Geldermalsen, where smoke leakage testing to EN 1634-3 is carried out alongside the certification work.
