34、wel) or the stack height of folded products (paper towels) are often measured. However, the fact that not only end-use tissue products, but also the base tissue paper from which these products are made, is the subject of trade between companies and countries, means that there is a genuine need for a
35、 consistent measure of thickness that can be applied to tissue products at any stage of their manufacture.The thickness of tissue paper and tissue products is known to be dependent on the pressure applied to the material at the time of measurement. Several different loading pressures, pressure-foot
36、diameters and loading speeds have been used within the tissue industry. This part of ISO 12625 has been prepared by harmonizing those standards applicable to tissue and tissue products currently in use. It specifies a single loading pressure, foot diameter and loading speed to be used for all thickn
37、ess measurements of tissue and tissue products.It is expressly stated that the detection of impurities and contraries in tissue paper and tissue products should be applied according to ISO 15755.For the determination of moisture content in tissue paper and tissue products, ISO 287 or ISO 638 should
38、be applied.DIN EN ISO 12625-3:2014-09 EN ISO 12625-3:2014 (E) 41 ScopeThis part of ISO 12625 specifies a test method for the determination of thickness and bulking thickness and the calculation of apparent bulk density and bulk of tissue papers and tissue products under a pressure of 2,0 kPa.NOTE Th
