Design and procedures for three round-robin tests of thermal insulation materials are described. The first, sponsored by ASTM Committee C-16 on Thermal Insulation, was intended to produce calibration and precision and accuracy data for ASTM Test for Thermal Conductance and Transmittance of Built-Up Sections by Means of the Guarded Hot Box (C 236) and a draft ASTM standard for a calibrated hot box test. The second, sponsored by International Standards Organization Technical Committee 163 on Thermal Insulation, covered guarded hot plate and heat flow meter tests of thermal resistance of thick thermal insulation materials, and was intended to produce calibration and precision and accuracy data for ISO specifications for such tests and those of each of the 22 participating countries—in the United States, ASTM Test for Steady-State Thermal Transmission Properties by Means of the Guarded Hot Plate (C 177) and ASTM Test for Steady-State Thermal Transmission Properties by Means of Heat Flow Meter (C 518). The third round-robin test involved tests of glass-fiber insulating material and was sponsored by ASTM Subcommittee C16.30 on Thermal Measurement and the Mineral Insulation Manufacturers Association.
