1.4.1.2 Security Grades shall meet the requirements of Section 12.
1.4.2 Any function 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 previously tested.
1.4.3 Function F21 or a similar function with dead bolts and function F04 or a similar function without
dead bolts to be certified shall be tested with the trim for qualification under Security Grades. All other
