Method and device for evaluating the quality of a layer of supple polymer foam.

摘要

Method for evaluating the quality of a layer of supple polymer foam (1), according to which method impression is made in the layer (1) with an impression body (11) and how the layer (1) reacts to this impression is verified, characterised in that with a pre-established constant in time impression in the layer (1) with the assistance of a dynamometer (10) the development of the force on the impression body (11) is registered in function of time and from this development in function of time a characteristic is calculated which depends upon the quality of the layer (1) and of which the relationship with the quality is already known via another method. <IMAGE>
