This paper describes the procedure, results, and error analysis from a study which characterizes a product lot of low-density, glass-fiber insulation material in terms of apparent thermal conductivity. The uncertainty of the measured values for each of the 75 specimens is estimated to be ± 1.4 percent. The data were taken at a mean temperature of 24°C (75°F), and the specimen thickness was 25.4 mm (1 in.). It is recommended that this lot be made available for distribution as a Standard Reference Material from the Office of Standard Reference Materials of the National Bureau of Standards.
