4.TEST EQUIPMENT
4.1 Door Provide a door structure of a conventional wood or metal door that is not mortised for hinges, or a skeletonized structure having an equivalent center of gravity in all directions after weights are applied.Hinge mounting surface of a door shall be a continuous steel strip with a minimum thickness of 1/4 in (6.4 mm). The dimension from the hinge axis to the edges of the mounting surfaces and to a plane parallel to the door face through the center of gravity of the door are listed in 8.2 for all sizes of square, full mortise hinges.Test door width is 36 in (914 mm).
4.2 Jamb A rigid, vertical steel jamb that is not mortised for hinges with a minimum thickness of 1/4 in (6.4 mm) shall be erected to hang the test door. Hinge mounting surfaces shall lie in the same plane and be plumb. Door stops or latching devices shall not be used. The door shall swing freely through a 90 degree test arc.
4.3 Blocks Steel jamb mounting blocks 1/4 in (6.4 mm) minimum thickness shall be provided for each of the hinges. They shall be of such rectangular dimensions as shall accommodate the leaves of the specimens and shall be over-sized to the extent that three 1/2 in- 20x 3/4 in (12.7 mm- 20 x 19 mm) hexagon head cap screws plus lock washers shall be applied to each block making it tight to the jamb (see 8.2). Holes for these cap screws shall be of such diameter as shall permit 1/8 in (3.2 mm) adjustment in all mounting plane directions before tightening.
4.4 Drilling Hinge jamb mounting blocks as well as door hinge mounting surface shall be drilled and tapped in accordance with the following: Template: Within .005 in (0.13 mm) of true position as shown by manufacturer's template drawing. Non-template: Within .005 in (0.13 mm) of the hole locations of the particular test specimen. Both hole patterns shall be accurately placed so that hinge-pin axes be normally collinear.
5.4 Application The hinges, fully assembled and with pins fully seated, shall be applied to the door using such screws supplied by the manufacturer. For alignment, a straight edge shall be laid along the edge of the door at such position as corresponds to the back edge of a recommended mortise. In applying the hinges, the back edge of the door leaf shall be abutted firmly against this straight edge as the screws are applied and tightened. Jamb mounting blocks shall then be applied to the hinge jamb leaves using the screws supplied.Screws shall be firmly tightened. The door with its three hinges and jamb mounting blocks, shall be positioned against the vertical jamb and the hexagon head cap screws and lock washers applied finger tight. Align edges of jamb leaves with straight edge and tighten cap screws securely. Door and jamb leaves of the hinges shall not be mortised.BHMA A156-1 pdf download.
