KERU Rating from UL Laboratories

Samples of handgun cases are submitted by manufacturers and subjected to this test program:

NORMAL OPERATION TEST:

Samples of the case were opened in accordance with the manufacturer's operating instructions to determine that they would operate as intended.

RESULTS

In order to receive a KERU rating the handgun case shall operate as intended in accordance with all manufacturer's operating instructions.

ENDURANCE TEST:

One case the the factory locking mechanism was operated through 1000 c of unlocking, relocking and unlocking.

RESULTS

In order to receive a KERU rating the lock shall operate properly during and after the 1000c.

ATTACK TEST:

Test Set-Up: A sample of the case was mounted onto a 3/4 in. thick piece of plywood so that the front edge and the left edge of the case were 2 in. from the edges of the plywood. Several inches of plywood were to the back edge and right edge of the case.

The case was secured to the plywood by four no. 10-24 steel machine screws, nuts and flatwashers. The plywood was then clamped to a fixed surface.

The attack tools consisted of a 1 lb head weight claw hammer and screwdrivers with 1/4 in. square shank no more than 8 in. long.

ATTACK NO. 1

The attacker shall pound on the lock with the 1 lb hammer in an attempt to break the locking mechanism. Approximately every 20 s the claw end of the hammer will be used in an attmpet to open the cover.

RESULTS

In order to receive a KERU rating, the case shall remain closed and clocked for an attack period of 3 minutes.

ATTACK NO. 2

The attacker shall use hammers and screwdrivers in an attempt to compromise the hinge.

RESULTS

In order to receive a KERU rating, the case shall remain closed and locked for an attack period of 3 minutes.

ATTACK NO 3

The attacker shall attempt to pry the case open using the allowable tools.

RESULTS

In order to receive a KERU rating, the case shall remain closed and locked for an attack period of 3 minutes.

DROP TEST

A sample of the gun case, with factory locking, shall have a 44 magnum revolver with a 6-1/2 in. barrel placed inside of the case and the case locked. The revolver shall not be loaded.

The case shall be dropped from a height of 5 ft onto a concrete floor five times as follows.

Drop No. Surface Impacted
1 Bottom of box
2 On left side of box
3 On right side
4 On one corner away from the hinge
5 On face, impacting the lock

RESULTS

In order to receive a KERU rating, the gun case shall not open in any of the drops. After operating the lock, the box shall open and permit removal of the revolver.

ADDITIONAL TESTING:

Upon receive of each handgun case design, additional testing may be conducted, unique to the particular design of the product, if vulnerabilities not contemplated under the above testing are considered evident.
