18、, na, Tue May 16 02:33:53 BST 2006, Uncontrolled Copy, (c) BSIEN 14477:2004 (E)41 ScopeThis standard describes a test method of determining the puncture resistance of a flexible packaging material.The method is applicable to multilayer flexible packaging materials.2 PrincipleA specimen of the flexib
19、le packaging material is fastened in a sample holder. A probe penetrates thespecimen with a constant speed. The force and the elongation needed to penetrate the specimen arerecorded.3 Apparatus3.1 Universal testing apparatus, with means of measuring elongation.3.2 Compression load cell3.3 Penetratio
20、n probe made of hardened steel as shown in Figure 1A 0,8 mm diameter probe with a rounded tip is used. The rounded tip of the probe shall have a radius of 0,4mm.3.4 Fixture for securing the probe to the load cell or to a solid base.3.5 Sample Holder as shown in Figure 2 or equivalent.3.6 Blanking pu
21、nch with an outer diameter matching the diameter of the sample holder shall be used.Licensed Copy: Wang Bin, na, Tue May 16 02:33:53 BST 2006, Uncontrolled Copy, (c) BSIEN 14477:2004 (E)5Dimensions in mm1 210 35 15 Key1 Probe tip 0,8 mm 0,005 mm2 Probe base 2,0 mm 0,010 mmFigure 1 Penetration probeL

23、:33:53 BST 2006, Uncontrolled Copy, (c) BSIEN 14477:2004 (E)74 CalibrationThe probe should be calibrated after at least 1000 measurements using a standard calibrating film made ofbiaxially oriented PET. The tip of the probe shall at the same time be checked for wear or damage using asuitable microsc
24、ope. The friction rubber shall be replaced at frequent intervals or at signs of wear.5 Test specimensA minimum of 10 specimens shall be cut out evenly spaced across the reel or sheet being tested. Thespecimens shall be conditioned at (23 2)C and (50 5)% RH for 48 hours before testing. The test shall
25、 becarried out at the same conditions.6 Probe speedThe test can be carried out at one of the following speeds expressed in mm/min: 1 - 5 - 10 - 50 - 100.7 Expression and calculation of resultsThe force is expressed in N and the elongation in mm. For the determination of the energy the integral below
26、the graph showing the force and elongation shall be calculated. Calculate the mean value and standarddeviation. A typical graph showing the force and elongation is shown in Figure 3.xNYKeyYForce in NX Elongation in mmFigure 3 Graph showing Force and Elongation (Schematic)Licensed Copy: Wang Bin, na,
