This National Standard of Canada is equivalent to American National Standard ANSI/BHMA A156.13-1987. 1.1 This Standard establishes requirements for Mortise Locks and Latches and includes operational tests, security tests, cycle tests, finish tests, and dimensional criteria. 1.2 Tests described in this Standard are performed under laboratory conditions. In actual usage, results may vary because of installation, maintenance, and environmental conditions. 1.3 When mortise 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 independent testing laboratory and shall be under an in-plant follow-up inspection service. 1.4 Grade Qualifications (Also see Appendix A) 1.4.1 Two classifications of Grades are described in this Standard. 1.4.2 Manufacturers shall indicate the Grade level of mortise locks and latches meeting both Operational Tests 9 and Security Tests 10 classifications. The grade in each classification shall be expressed separately. 1.4.3 Any function with escutcheon trim shall be tested for qualification under Operational Grades and all other functions shall be considered as meeting the criteria provided the lock case and operating parts are of the same construction as that of the lock tested. 1.4.4 Function F21 or a similar function with dead bolts and function F04 or a similar function without dead bolts with the trim to be certified shall be tested for qualification under Security Grades. All other functions where access is prevented shall be considered as meeting the criteria provided the lock case and operating parts are of the same construction as that of the lock tested.
