19、25-3:2014(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject fo
20、r which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on
21、all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted.
22、This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any
23、or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the convenience of user

32、ckness-related parameters, such as the roll diameter of rolled products (kitchen towel) 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
33、 of trade between companies and countries, means that there is a genuine need for a 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 mater
34、ial at the time of measurement. Several different loading pressures, pressure-foot 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
35、 single loading pressure, foot diameter and loading speed to be used for all thickness 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
36、of moisture content in tissue paper and tissue products, ISO 287 or ISO 638 should be applied.vi ISO 2014 All rights reservedBS EN ISO 12625-3:2014INTERNATIONAL STANDARD ISO 12625-3:2014(E)Tissue paper and tissue products Part 3: Determination of thickness, bulking thickness and apparent bulk densit

46、(g/m2).4 PrincipleMeasurement of the thickness of a test piece of tissue paper sampled during the manufacturing process or of a tissue product supplied as a finished article. The measurement being made as the distance between a fixed reference plate on which the sample rests and a parallel pressure-
47、foot that exerts a specified load on the area under test.5 Apparatus5.1 Precision dead-weight micrometerThis has two parallel, horizontal faces, flat to within 0,003 mm, between which the test piece is placed. The lower face shall be fixed and the upper face (pressure-foot) moveable in a direction p
48、erpendicular to the plane of the fixed face.The upper, circular, pressure-foot shall have a diameter of (35,7 0,1) mm giving a nominal area of 10,0 cm2and shall be parallel to the lower face within limits defined in Annex B.3.The lower face shall be constructed to support the test piece such that th
49、e test piece lies flat while under test. In practice, the lower face should have minimum dimensions 20 % larger than the diameter of the pressure-foot. The pressure between the two faces shall be (2,0 0,1) kPa (see Annex C).The measuring speed shall be (2,0 0,2) mm/s.The instrument read-out/scale shall be graduated in increments of 0,001 mm.The opening between the pressure-foot and the lower face is set by agreement between the instrument supplier and the customer. For most thickness measurements, instruments with an
