12-3-5.1 Sample Selection
12-3-5.1.1
Representative samples of the releasing system shall be assembled to a test fixture as described in the installation instructions, unless otherwise noted in specific tests. The assembly shall include the mounting, hardware, releasing mechanisms and fasteners recommended in the instructions.
12-3-5.1.2
Samples to be tested shall include each type and sizes of releasing system shown in the installation instructions. Each type of releasing mechanism shall be subjected to the complete test program, unless it can be shown that tests on one type of mechanism are representative of the worst case testing on another mechanism. The sample shall be tested with mounting hardware and security bars that represent the worst case conditions of use. This shall be considered to be the security bars with the heaviest weight, greatest dimensions, and systems that create the greatest torque, moment and frictional forces on the hinges and releasing mechanism.
12-3-5.1.3
The test report shall document the systems tested, along with the basis for sample selection.
12-3-5.2 Test Fixture
12-3-5.2.1
The test fixture in which the assembly is mounted shall consist of the wood stud construction described in Section 12-3-5.2.2. Systems that require a specific mounting arrangement not represented by these test fixtures, such as masonry or brick, shall be mounted in a fixture of equivalent dimensions and rigidity, as described in the installation instructions. If agreeable to the testing laboratory and manufacturer, the wood stud fixture shall be representative of all mounting structures, provided the system is securely held in place in the fixture during all tests.
12-3-5.2.2
The entire test fixture shall be constructed of commercially available two by four trade size vertical wood studs [nominal 1.5 inches by 3.5 inches (38.1 mm by 89 mm)], spaced on maximum 16 inch (406 mm) centers. The opening shall be framed with two by four plates and minimum two layers of two by four for headers. For window openings, a minimum of two layers of two by four shall be used for the sill and cripple studs shall be provided. The frame shall be secured in place so it does not move when the system is subjected to the test forces noted below. The frame shall extend a minimum of 12 inches (305 mm) above and on each side of the opening.
12-3-5.2.3
Actual doors and windows or their frames shall not be required to be mounted in the opening unless the presence of such doors, windows or frames affects the operation of the system, or unless part of the system is mounted on the door or window frame.
12-3-5.2.4
The exterior side of the assembly shall be covered by 3/4-inch (19 mm) thick trade size CDX plywood, secured with minimum 11/2-inch (38 mm) nails or screws, secured at least every 12 inches (305 mm) to each stud, sill and header. The interior side of the assembly shall be covered with a layer of 1/2-inch (13 mm) gypsum wallboard, secured with minimum 11/4-inch (32 mm) nails or screws at least every 12 inches (305 mm) to each stud, sill and header.
12-3-5.2.5
Openings in the test fixture shall be sized to accommodate the size of the assembly under test, as described in the installation instructions. Opening size shall be allowed to vary if the size used is judged to not affect the results of any test performed.
12-3-5.3 Sample Assembly
12-3-5.3.1
Samples of the releasing system shall arrive at the test site in the packaging anticipated for distribution and sale, and accompanied by the installation instructions. The samples are to be installed on the test fixture by a representative of the certification organization, using common hand and power tools as recommended by the instruction manual. Any specialty tools required for assembly shall be so identified in the instructions.
12-3-5.3.2
When multiple tests are required on an assembly, they are allowed to be performed on the same test fixture, provided that new hole or openings are used for mounting. Portions of the test fixture shall be allowed to be replaced to accommodate new mounting holes or brackets.
12-3-5.3.3
Samples that include grease, graphite, silicon or other lubricants shall also be tested with the lubricant removed or not applied.
12-3-5.3.4
When assembled in accordance with the installation instructions the system shall be securely held in place in the test fixture and shall operate consistently in the intended fashion.
