Standard Safety Specification for Non-Integral Firearm Locking Devices
SCOPE
1.1 This specification covers non-integral locking devices used to increase safety on unloaded firearms.
1.2 This specification contains functional, operational, and safety requirements for non-integral firearm locking devices. Included are function descriptions, force tests, and surreptitious entry tests as set forth in Section 5.
1.3 The specification is intended to apply only to non-integral locks or locking mechanisms applied to, in, around, or about a firearm, either external to the firearm or by some method of introduction to or within the firearm. The specification is not intended to set evaluation standards by which safety levers, firing pin blocks, or other traditional discharge prevention mechanisms are evaluated, notwithstanding the fact that these mechanisms may prevent inadvertent discharge. This specification is not applicable to devices used for, or intended for, the prevention of theft or other intentional misuse of firearms.
Note 1: Tests described are laboratory type tests and although they may simulate some field conditions, they do not duplicate all field test conditions.
Note 2: There is no apparent comparable ISO/IEC standard.
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.5 The following precautionary caveat pertains only to the test method portions of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

INTRODUCTION
This specification is intended to establish means of determining whether locking devices applied to
a firearm adequately serve the purpose of deterring the unauthorized use of firearms.
Subcommittee F15.53 on Non-Integral Firearm Locking Devices has been working to develop a
performance standard for these products. Our first meeting was held inApril 2001, after the Consumer
Products Safety Commission and others requested thatASTM organize an effort to develop a standard
for gun locks. Representatives of manufacturers, purchasers, user groups, and others have voluntarily
contributed their time and energy toward a common goal.
Thesubcommitteedefinedthescopeoftheirworktoexcludelockboxes,andSubcommitteeF15.55

contributed their time and energy toward a common goal.
The subcommittee defined the scope of their work to exclude lock boxes, and Subcommittee F15.55
has since been formed to work on a standard for those products. Subcommittee F15.53 decided to
target a single, minimum performance standard for all devices, as opposed to defining several “grades”
or performance levels. Finally, the subcommittee focused on test methods that were objective,
realistic, reliable, and repeatable.
1. Scope
1.1 This specification covers non-integral locking devices used to increase safety on unloaded firearms.
1.2 This specification contains functional, operational, and safety requirements for non-integral firearm locking devices.
Included are function descriptions, force tests, and surreptitious entry tests as set forth in Section 5.
1.3 The specification is intended to apply only to non-integral locks or locking mechanisms applied to, in, around, or about a
firearm, either external to the firearm or by some method of introduction to or within the firearm. The specification is not intended
to set evaluation standards by which safety levers, firing pin blocks, or other traditional discharge prevention mechanisms are
evaluated, notwithstanding the fact that these mechanisms may prevent inadvertent discharge. This specification is not applicable
to devices used for, or intended for, the prevention of theft or other intentional misuse of firearms.

use and shall pass the testing procedures described in this specification.
4.6 The firearm locking device, when properly installed on a firearm, shall not be disabled through disassembly of the firearm,
and subsequent reassembly of that firearm.
5. Testing Procedures
5.1 General:
5.1.1 All tests shall be conducted within the following tolerances as applicable:
5.1.1.1 Force: 0.5 % of working range.
5.1.1.2 Height: 66 mm (0.25 in.).
5.1.1.3 Torque: 4.0 % of reading.
5.1.1.4 Weight: 610 g (0.02 lb).
5.1.2 All tests shall be conducted at temperatures between 16 and 27°C (61 to 81°F).
5.1.3 Each test in this section shall be performed on a locking device that has been subjected only to the preconditioning
specified in 5.1.5.
5.1.4 Test methods shall be performed on each firearm locking device model submitted for testing pursuant to this standard in
an attempt to disable the device.
5.1.5 Open and close locking device fully 100 times prior to testing.
5.2 Picking or Manipulating Test:
5.2.1 Picking Test—This test does not apply if the device does not have a keyway. The firearms locking device shall resist
picking with the use of paper clips (jumbo size), paper clips (#1 size), and small screwdrivers that fit in the keyway for 2 min with
each of these tools. Time shall be counted only while tools are in contact with the lock. If the lock is disabled during the 6 min
of manipulation, picking tests are performed on three additional samples. Failure occurs if any one of the three additional samples
is disabled.
5.2.2 Combination Manipulation Test—This test does not apply if the device does not have a combination lock mechanism. The
firearms locking device shall resist manual manipulation by dialing the combination wheels or pushing the combination buttons
or manipulating other combination lock means by hand for 2 min. Manipulation is limited to the combination mechanism. Time
shall be counted only while hands are manipulating the lock. Failure occurs if the lock is disabled without the proper combination
being entered during 2 min of manipulation.
5.3 Shock Test:
5.3.1 Using the shock impact fixture referenced in 2.1, drop a 1 kg (2.2 lb) weight from a distance of 1 m (39.4 in.) five times
onto the firearm locking device, which is oriented so that a flat blade screwdriver can impinge upon and penetrate along the rotation
axis into the keyway, or for a combination lock, onto the combination mechanism. Additionally, using the shock impact fixture,
drop a 1 kg (2.2 lb) weight from a distance of 1 m (39.4 in.), five times to the side opposite the keyway or the combination
mechanism, of a firearm locking device using the anvil rod (see Specification F883, Detail 5).
NOTE 5—If this second shock test on the side opposite the keyway or combination mechanism is not possible, the tester is to use discretion and hit
the most vulnerable side. Failure occurs if the firearm locking device is disabled by the shock test.
5.4 Tensile Test—Specific fixtures may be required to allow application of the required force to the individual components.
5.4.1 For firearm locking devices that have clamping components, support the firearm locking device in a fixture designed to
enable application of forces in tension along a central axis of the mating locking components of the firearm locking device. Apply
1000 N (225 lb) of force slowly along the central axis of the firearm locking device locking components without interfering with
or giving support to any of the mating locking components of the firearm locking device. Failure occurs if the firearm locking
device is disabled by the tensile test.
5.4.2 For firearm locking devices that have cable locking components, support the firearm locking device in a fixture designed
to enable application of forces in tension along a central axis. Apply 1000 N (225 lb) of force slowly along the axis. Failure occurs
if the firearm locking device is disabled by the tensile test.
5.5 Cutting Test:
5.5.1 Shackle Cutting Test—This test does not apply if the device does not have a shackle. The shackle of the firearm locking
device shall withstand cutting through when two blades made of steel, hardened to a minimum hardness of Rc50, are used in
conjunction with the blade positioning holder of the cutting fixture. The shearing assembly must then be placed in a device having
a compression load capability and compressed with a force of 4450 N (1000 lb). See Specification F883 for details. Failure occurs
if the firearm locking device is disabled.
F2369 − 04 (2016)
5.5.2 Cable Cutting Test—This test does not apply if the device does not have a cable. Use a fixture that meets the requirements
of ASME B107.20M, Sections 4.2 Wire Cutting, 4.3 Paper Cutting, 5.1 Cut Test, and 5.2 Hardness Test for Type 1 (Lineman’s)
Pliers in accordance with ASME B107.25M, Sections 5.2.1 Wire Cut Test, 5.2.2 Paper Cut Test, and 5.3.3.2 Jaws (Pliers Hardness
Test). The cable of a firearm locking device shall withstand cutting through with a machine force of 3336 N (750 lbf) applied
gradually over not less than 10 s, for a duration of 30 s with the firearm locking device supported on both sides of the point of
the shear cut with allowance for blade clearance. Failure occurs if the firearm locking device is disabled.
