3.1 Cylinders and Input Devices for Locks Cylinders supplied or mated with locks shall meet the performance requirements for the appropriate cylinder types and grade level found in the ANSI/BHMA Standard A 156.5-2010 for Cylinders and Input Devices for the lock to retain its grade listing. Assemblies take the grade level of the lowest graded component. Other mechanisms are permitted to be used in lieu of cylinders providing the performance and security criteria are equivalent to that of cylinders. Suffix D shall be indicated in the certified products directory for locks to be used only with drill resistance cylinders as evaluated in A156.5.
3.2 Tolerances Where only minus tolerances are given, the dimensions are permitted to be exceeded at the option of the manufacturers. All values which do not carry specific tolerances or are not marked maximum or minimum shall have the following tolerances: Linear dimensions shall be±1/16 in. (1.6 mm). Pounds or pound force shall be±2%. Degrees shall be±2 degrees.
3.3 Where levers are referenced, knobs, paddles, or handlesets are permitted to be used, except for tests which apply to specific trim.
3.4 Roses, escutcheons, knobs, levers, turns, paddles, and cylinder guards shall cover all door preparation openings.
3.5 No lock can provide complete security by itself. Locks may be defeated by forcible or technical means, or evaded by entry elsewhere on the property. No lock can substitute for caution, awareness of your environment, and common sense. Builders hardware is available in multiple performance grades to suit the application. In order to enhance security and reduce risk, consult a qualified locksmith or other security professional. For applications where pick resistance and other higher security protections are required users should consider locks meeting UL 437 or ANSI/BHMA A156.30 for High Security Cylinders.
