Abstract The invention relates to a process and an apparatus for defining the properties and/or composition of moulding sand in casting works, wherein some of the properties are defined in a test sleeve (5) which receives a moulding sand sample. In order to create a process or a testing method which make it possible to more quickly and easily determine the properties of the moulding sand which are essential for purposeful use, the invention proposes to take an ultrasonic measurement of the sample of moulding sand, wherein, independently of this, at least one further property of the sample of moulding sand is measured or defined, and the combined results of the ultrasonic measurement and further measurement operation are used to define the composition and/or moulding technological properties of the sample. In order to create an apparatus which makes it faster and simpler to define the properties of the moulding sand which are important for purposeful application, it is proposed according to the invention that an ultrasonic converter is provided on at least one surface which delimits the testing body.
