- Abstract
- The National Bureau of Standards (NBS) has developed the capability to provide thick, low-density thermal insulation calibrated transfer samples to the thermal testing community. The calibrated transfer samples are described. The considerations that went into the selection and preparation of these low-density mineral-fiber samples are discussed. The contributions to the calibration uncertainty due to material variability are discussed and estimated to range between one percent and 2.5 percent.
