29、E) DIN EN ISO 12625-9:2015-05 IntroductionThis part of ISO 12625 is applicable to tissue papers and tissue products. In principle, application to other paper types is possible, but not covered by this part of ISO 12625.It is expressly stated that the detection of impurities and contraries in tissue
30、and tissue products be applied according to ISO 15755.For the determination of moisture content in tissue paper and tissue products, ISO 287 and ISO 638 are applied.4EN ISO 12625-9:2015 (E) DIN EN ISO 12625-9:2015-05 1 ScopeThis part of ISO 12625 specifies a test method for the determination of the
31、resistance to mechanical penetration (ball burst strength procedure) of tissue paper and tissue products.Currently, two types of clamping devices are available on the market with two different diameters, one is with 50 mm and one is with 89 mm (see Annex B). This part of ISO 12625 applies for a 50 m
32、m clamping device to be able to measure all sample sizes of tissue paper and tissue products and to be consistent with ISO 12625-11.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

36、etermined by the procedure specified in ISO 12625-6Note 1 to entry: The grammage is expressed in gram per square metre (g/m2).3.2bursting forceFmaximum force that a test piece of tissue paper or tissue product can withstand under the test conditions, applied at right angle to its surfaceNote 1 to en
37、try: The bursting force is expressed in newton (N).5EN ISO 12625-9:2015 (E) DIN EN ISO 12625-9:2015-05 3.3burst indexXbursting force of tissue paper or tissue product divided by the grammageNote 1 to entry: The burst index is expressed in newton square metre per gram (Nm2/g).4 PrincipleThe test cons
38、ists of measuring the resistance force of a highly polished stainless steel burst ball, moving at a constant speed, penetrating perpendicularly a tissue test piece that is clamped between the two concentric rings.5 Apparatus5.1 GeneralThe apparatus shall be placed on a horizontal surface, free from
39、externally induced vibrations.5.2 Clamping systemThe clamping system is designed to clamp the test piece firmly and uniformly between two concentric annular plane, parallel surfaces with same internal diameter. The clamping rings can be activated mechanically or pneumatically. The principle of the c
40、lamping system, using a pneumatic fixture is illustrated in Figure 1.Key1 load cell 5 movable ring2 travel 6 pneumatic cylinder3 stationary ring 7 probe4 suitable band made of rubber (e.g. polychloroprene rubber)apolished stainless steel ballFigure 1 Principle of the clamping system, pneumatic fixtu
41、re6EN ISO 12625-9:2015 (E) DIN EN ISO 12625-9:2015-05 The clamping pressure shall be sufficient to prevent slippage during the test while avoiding damaging the test pieces (e.g. including a weakness point near or under the clamping ring that could influence the results).The clamping surfaces of the
42、clamping rings shall be covered with a band made of a suitable commercial grade rubber material (e. g, polychloropren rubber), typically 1,0 mm to 2,0 mm thick having an IRHD hardness (International Rubber Hardness Degree) of 70 IRHD to 85 IRHD.The inner edges of the annular rubber ring shall be coi
43、ncident with the inner diameters of the clamping rings and the band shall be at least 12,5 mm wide.The internal diameter of the two concentric rings shall be (50,0 0,2) mm (see Annex B).For the dimensions of the clamping system, see Figure 2.Dimensions in millimetresKey1 test area2 clamp ring covere

45、ed to transmit force applied to the ball from the test piece. The penetration ball shall be made of highly polished stainless steel and shall have the following dimensions: diameter: (16 0,2) mm; sphericity: better than 1 m.The penetration ball shall be centred with respect to the annular clamps. Th
46、e diameter of the rod shall be smaller than the diameter of the ball. 5.4 Force-measuring systemThe force-measuring system shall measure loads with an accuracy of 1 % of the reading or 0,1 N, whichever is greater and shall be calibrated and verified to conform to the requirements according to ISO 75
47、00-1. The load cell system shall have a measuring range of 0,1 N to 50 N. The readout system shall have a display that shows the maximum force at burst.5.5 Drive mechanismThe drive mechanism shall consist of a static uniaxial testing machine with a suitable mechanism for moving either the clamping s
48、ystem or the penetration system so that they approach each other at a constant rate in a direction perpendicular to the clamping system plane. The penetration test speed shall be (125 5) mm/min.7EN ISO 12625-9:2015 (E) DIN EN ISO 12625-9:2015-05 6 SamplingIf the tests are being made to evaluate a lo
49、t, the sample shall be selected in accordance with ISO 186.If the tests are being made on another type of sample make sure that the specimens taken are representative of the sample. Each test piece shall be free from perforations and faults not normally inherent in the tissue.7 ConditioningCondition the samples according to ISO 187 and keep them in the standard atmosphere throughout the test.8 Preparation of test pieces8.1 GeneralTest pieces shall be
