4.1 Test Door
Provide a structure to support a standard 18 gauge steel door and a standard 16 gauge steel door frame.The door(s) shall be 36 inx 84inx 1 3/4 in(914 x 2134 x 44 mm) nominal with an 1/8 in (3.175 mm) per 2 in (50.8 mm) bevel both edges. For testing astragals on pairs of doors, the inactive leaf shall be held in position, with a gap between the meeting edges of the pair measuring 1/8 in +/- 1/16in (3.175 mm +/- 1.587 mm). Air leakage rates for perimeter and meeting edge seals are permitted to be tested separately, and added together to represent the assembly. Where required by the application and approved by the test lab, doors of other materials may be substituted provided the setup results in equivalent conditions and meets manufacturer's installation specifications. Adjust the frame before installing the door so that it is level, plumb and square within 1/32 in (0.8 mm). The door shall be hung with three4 1/2x4 1/2 in(114x 114 mm) Grade 2 full mortise hinges meeting the requirements of ANSI/BHMA A156.1 for Butts and Hinges. Install a function F81 or F82 Grade 1 bored lockset located at 40 in (101 6mm) plus or minus 2in. (50.8mm) from the finished floor. The lockset shall meet the requirements of ANSIBHMA A156.2 for Bored and Preassembled Locks. The strike plate shall be in accordance with ANSI/BHMA A115 and mounted in the door frame so that when the door is closed and the latch bolt is engaged in the strike plate, a 1/16 in (1.6 mm) space is maintained between the door face and the stop on the frame. Check the alignment of the door in the frame and adjust as necessary by shimming the hinges so that the resulting gaps between the door and frame are parallel within 1/32 in (0.8 mm) and that the spacing is as follows, and as illustrated in Figure 1. Take the measurements from the high side of the bevel. See figure below.
4.4 Environmental Test Chamber
Provide an air-circulating chamber capable of exposing the test samples in a vertical orientation, and providing the cycle described in section 7.2. The chamber shall allow free circulation of air and humidity, and be large enough to contain the applicable fixtures described in the standard. The chamber shall be capable of raising or lowering the temperature and humidity in accordance with the test cycle requirements.BHMA A156-22 pdf download.
