Beschreibung
Zusammenfassung:	The invention relates to a method and a device for determining the properties and/or the composition of foundry moulding sand, in which some of the properties are determined in a test sleeve (5) receiving a sample of moulding sand. In order to provide a method and a test method which allow a simpler, more rapid determination of properties of the moulding sand which are essential for a planned use, it is proposed according to the invention that an ultrasonic measurement be undertaken on the sample of moulding sand, at least the measurement or determination of one further property of the sample of moulding sand being carried out independently hereof and, from the combined results of the ultrasonic measurement and the further measurement, the composition and/or the technological properties of the sample are determined. In order to provide a device which allows a simpler, more rapid determination of properties of the moulding sand which are essential for a planned use, it is proposed according to the invention that an ultrasonic transducer be provided on at least one surface adjacent to the test body.
