Endorsement notice The text of ISO 12625-4:2016 has been approved by CEN as EN ISO 12625-4:2016 without any modification. ForewordISO (the International Organization f
29、or 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 for which a technical committee has been established has th
30、e 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 all matters of electrotechnical standardization.The proce
31、dures 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. This document was drafted in accordance with the editoria

48、, the tensile strength, the corresponding stretch at maximum force and the tensile energy absorption can be calculated.The test can be carried out by a vertical or a horizontal tensile strength tester. Precision data are available in Annex A.5 Apparatus5.1 Tensile-testing apparatus5.1.1 GeneralThe tensile-testing apparatus shall be in accordance with ISO 1924-2. It is capable of stretching a test piece of tissue paper or tissue product of given dimensions, at a constant rate of elongation of (50 2) mm/min, and recording the tensile force as
