A hot-box test facility, in which the equipment is capable of operating in either a calibrated or a guarded mode, is described. The basic design consists of a separate cold box, hot box, specimen frames, refrigeration unit, control and data-acquisition panel, and metered box. Both the hot and cold boxes are insulated with low-density polyurethane foam, with an overall minimum thickness of 30.5 cm (12 in). The attitude of the test facility can be varied to provide upward, downward, or horizontal heat flow. Both the hot and cold boxes can provide variable air velocities parallel to the specimen face. The following is a summary of the operating characteristics of the test facility: test specimen area dimensions: 2.4 by 2.4 m (8 by 8 ft); guarded mode metering area: 1.8 by 1.8 m (6 by 6 ft); cold side: normal temperature range: 27 to -23/sup 0/C (80 to -10/sup 0/F), special temperature range, to -46/sup 0/C (to -50/sup 0/F), air velocity: 0.8 to 24 km/h (0.5 to 15 mph); hot side: temperature range: 2 to 71/sup 0/C (35 to 160/sup 0/F) and air velocity: 0.8 to 24 km/h (0.5 to 15 mph).
