This adjunct describes the line-heat-source guarded-hot-plate apparatus fabricated by the National Institute of Standards and Technology. It is intended as a guide in the design and construction of a guarded hot plate having circular line heat sources. The essential requirements for steady-state testing of heat insulators are described in ASTM Test Method C 177 and the essential requirements for the design of guarded hot plates having circular line-heat-sources are covered in ASTM Practice C 1043.
