Terms defined. For the purpose of this chapter, the following terms
shall have the meanings indicated:
ATTACKS
Physical methods used by burglars in gaining or attempting
to gain illegal entry. The attacks are: ramming, kicking, pushing
and pulling, lifting, loiding, breaking, prying, spreading, smashing,
picking, wrenching, popping, pulling, removing and inside unlocking.
BOLT
A metal bar which, when actuated, is either projected (or
thrown) horizontally or vertically into a solid mass to prevent a
door, window or other object from moving or opening.
BOLT PROJECTION
That distance from the edge of the door to the furthest point
on the bolt in the projected position.
BURGLAR-RESISTANT MATERIAL
Framed glass or glass-like materials that will withstand
the impact of a five-pound steel ball dropped from a height of forty
(40) feet and five (5) impacts from a height of ten (10) feet without
release from its frame.
BURGLARY RESISTANCE
The characteristic of a building or building component to
withstand forcible attack applied for the purpose of accomplishing
successful entry. "Burglary resistance" may be described in terms
of time, energy, force or a combination of these variables.
BURGLARY-RESISTANT GLAZING
Glazing material capable of withstanding five (5) fifty-foot-pound
impacts, as produced by dropping a three-and-one-fourth-inch diameter
hardened smooth steel ball, weighing five (5) pounds, through a vertical
distance of ten (10) feet; alternatively defined as "burglar-resistant
material" hereinbefore.
COMBINATION DEADLATCH AND DEADLOCK
A device combining a deadlatch operable by knobs from inside
and outside with a deadlock operable from inside by a thumb turn or
key and from outside by a key, both of which can be retracted from
inside by turning the knob and from outside by a key.
CYLINDER
The cylinder of a lock is the cylindrical subassembly containing
the tubular mechanism and the keyway actuated by the correct key(s)
or knob, not to be confused with a "cylinder lock," which is a misused
term to describe a key-in-knob lock. A double cylinder lock is one
which has a key-actuated cylinder on both sides of the lock.
CYLINDER GUARD
A hardened steel ring or plate surrounding the otherwise
exposed portion of a cylinder lock to prevent cutting, drilling, prying,
pulling or wrenching with common tools.
DEAD BOLT

a latch bolt, which does. The bolt must be actuated by a key and/or
an interior knob and becomes locked against return by end pressure
when projected.
DEADLATCH
A latch which is positively held in latched position with
a strike by an added, integral bolt-type mechanism and is again released
by a key from the outside and a knob or similar actuator from the
inside.
DEADLOCK
A locking device with a bolt, not spring-loaded, which engages
and disengages a strike by the use of a key from the outside and/or
inside.
DEADLOCKING LATCH
A latch equipped with a locking device which, when in a closed
position, causes the latch to resist being retracted by pressure applied
to it (also called a spring bolt with anti-shim device), alternatively
defined as follows:
(1)
A latch in which the latch bolt is positively held in the protected
position by a guard bolt, plunger, or auxiliary mechanism.
(2)
A lock bolt with a beveled end which is spring-actuated, but
can be automatically or manually locked against return by end pressure
when projected.
DOOR
A movable frame of wood or other material on hinges giving
ingress to or egress from a room, building or other enclosure.
DOOR ASSEMBLY
That unit composed of a group of parts or components which
make up a closure for a passageway through a wall. The "door assembly"
for this standard is made up of the following parts: the door; hinges;

push plates); miscellaneous hardware and closures; the frame, including

JAMB
The vertical members of a door frame, e.g., those fixed members
to which the door is secured.
JAMB/STRIKE
That component of a door assembly which receives and holds
secure the extended lock bolt; both the strike and jamb, used together,
