Certification is often mistakenly referred to as an "approval", which is not true. Organizations such as Underwriters Laboratories, TÜV Rheinland, NTA Inc, and CSA International will test the products according to standard procedures and "list" them as compliant to that standard. They do not "approve" anything except the use of the mark to show that a product has been certified for compliance with such specific standard. Thus, for instance, a product certification mark for a fire door or for a spray fireproofing product does not signify its universal acceptance for use within a building. Approvals are up to the Authority Having Jurisdiction (AHJ), such as a municipal building inspector or fire prevention officer. Conversely, FM Global does use the term "Approvals" for its certification listings, which are intended for use of the products within buildings that are insured by FM Global. The German accreditor Deutsches Institut für Bautechnik (DIBt) issues "Approvals" for systems. All of these listed products must conform to listing and approval use and compliance.
