Standard for Residential Deadbolts
Establishes requirements for residential deadbolts and deadlatches, and includes durability, security, finish tests. Residential deadbolt and deadlatches are generally used for single family homes and multifamily dwellings. Tests described in this Standard are performed under laboratory conditions. In actual usage, results vary because of installation, door and frame construction, maintenance and environmental conditions. When locks and latches are used in fire door assemblies, they shall have been tested and listed for use in fire doors by a Nationally Recognized Testing Laboratory (NRTL) and shall be under an in-plant followup inspection service. Tests to evaluate decorative and protective finishes for these products are described in ANSI/BHMA A156.18 for Materials and Finishes and are required to complete certification.
