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

47、924-2:2008, 3.74 PrincipleA test piece of tissue paper or tissue product, of given dimensions, is stretched to break at a constant rate of elongation using a tensile-testing apparatus that measures and records the tensile force as a function of the elongation of the test piece.From the recorded data

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
