Abstract:

A small experimental apparatus was designed for the measurement of total hemispherical emittance of thin flat disc specimens over the tempera ture range of 0F to 300F. It is a steady-state device which employs thermal radiation from a hot wall for specimen heating. An equation is developed for the calculation of specimen emit tance for which only temperatures need be measur ed between 40F and 100F, justifies an anticipat ed maximum error of 3 for high emittance specimens.
