NBN EN 1969:2000

This European Standard specifies two methods for the determination of the thickness of synthetic surfaces for sports areas, suitable for use in the laboratory and 'in situ'. Method A, a destructive test method, is intended for use - where the thickness needs to be measured to an accuracy of +/-0,1mm;- when the thickness of different layers is to be determined. Method B, a non-destructive test method,is intended for use as a routine check on thickness, e.g.for control purposes or when surveying a large area of synthetic surfacing. It gives measurements to an accuracy between +/-0,5 and +/-1,5mm, depending upon the textur
