Volume, ASTM STP 1454. American Society for Testing and
Materials. |PDF (127Kb) | The in situ real time measurement of
the regression rate of a melting interface (RRMI) is performed
by the ultrasonic measurement system reported here. The RRMI is
the rate at which a solid/liquid interface (SLI) moves along a
metallic rod while burning in an oxygen-enriched atmosphere and
is an important flammability indicator. The ultrasonic
transducer and associated equipment used to drive the transducer
and record the echo signal is described, along with the process
that transforms the acquired signals into a RRMI value. Test
