Establishes uniform methods of laboratory testing for rating the thermal performance of ceiling panels manufactured for radiant panel heating and cooling of indoor spaces.

The standard covers steady-state testing of ceiling panels at panel surface temperatures from 24éC (75éF) to 65éC (149éF) for nonmetal heat transfer elements in the ceiling panel or from 24éC (75éF) to 150éC (302éF) for metal heat transfer elements in the ceiling panel. Sensible cooling ceiling panels are tested from 14éC (57éF) to 24éC (75éF).

The standard also provides correction factors with respect to defined test conditions for the size of the test room, barometric pressure in the test location, and average air velocity in the vicinity of the test panels in order to ensure repeatable test results.
