Abstract
The paper presents a data reduction method for determination of therma l diffusivity in flash method. It is based on non-linear chi(2) fit to a model which takes into consideration heat losses. The advantage of the method is that it does not need a knowledge of base line and is su itable for data disturbed by noise and mains hum. A comparison with so me other data reduction methods is given.
