Abstract

After a review of the calibration of two heat flow meter (HFM) transducers, the HFM has been redesigned. The new design produces a calibration independent of the characteristics of the material being tested; that is, it produces the same calibration curve for thick, low-density specimens as for thin, high-density ones. Calibration within ±1 percent of transfer standard accuracy is discussed; the HFM precision for thick specimens of low-density glass fiber appears to be higher than that of a guarded hot plate under the same testing conditions.
