The IFO certification body provides impartial and independent monitoring services for powder coating companies. DIN 55633 describes the corrosion protection of steel structures by powder coating systems. It covers powder coating materials and systems for different environmental conditions, surface preparation and pre-treatment, expected period of protection, laboratory tests to assess systems and the execution and monitoring of coating work. The standard relates to steel structures whose components are made of alloy or low-alloy steel (as per DIN EN 10025, for example) that is at least 3 mm thick, which have been designed in compliance with a structural safety certificate and which are uncoated or hot-dip galvanised (in accordance with DIN EN ISO 1461).
