NF T54-116<\/h1>\n

Film Pendulum Impact Test<\/h2>\n

<\/h2>\n

The NF T54-116<\/strong> standard defines a reliable method for measuring the impact resistance of plastic film<\/strong> kasutades pendulum shock test<\/strong>. It is especially valuable for evaluating the performance of flexible films used in packaging, pharmaceuticals, electronics<\/strong>, ja meditsiiniseadmete materjalid<\/strong>. By using this method, manufacturers can determine how well a film resists sudden impacts that could lead to ruptur<\/span>e or puncture during ha<\/span>ndling, transporta<\/span>\"NFtion, or use.<\/span><\/p>\n

Veebilehel Cell Instruments<\/strong>, we specialize in offering advanced film pendulum impact testers<\/strong>, nagu n\u00e4iteks PIT-01<\/strong><\/a>, that meet NF T54-116 and global standards like ASTM D3420<\/strong>. In this article, you\u2019ll learn what NF T54-116 entails, how the test is performed, and why it\u2019s essential for quality control.<\/p>\n

Film Pendulum Impact Tester and Related Standards<\/h2>\n

The film pendulum impact tester<\/strong> is designed to simulate mechanical shock on thin plastic sheets by measuring the energy required to puncture them. The pendulum impact resistance of plastic film<\/strong> is a critical property that reflects the material\u2019s ability to withstand real-world conditions.<\/p>\n

NF T54-116 is frequently used alongside international standards, including:<\/p>\n

    \n
  • \n

    ASTM D3420<\/strong> \u2013 Standard Test Method for Pendulum Impact Resistance of Plastic Film<\/p>\n<\/li>\n

  • \n

    Spencer Impact Test<\/strong> \u2013 Used in North American labs and often performed using spencer impact testing equipment<\/strong><\/p>\n<\/li>\n

  • \n

    GB\/T 8809<\/strong> \u2013 China\u2019s national standard for film impact resistance test<\/strong><\/p>\n<\/li>\n<\/ul>\n

    These standards, although varied in procedures, all aim to assess film pendulum impact resistance<\/strong> to support product development, compliance, and quality assurance.<\/p>\n

    \n

    How the NF T54-116 Pendulum Shock Test Works<\/h2>\n

    NF standard specifies the use of a pendulum impact test system<\/strong> that incorporates a hemispherical striker and a rigid specimen clamping mechanism. Here\u2019s how the method works:<\/p>\n

    Test Principle:<\/strong><\/p>\n

      \n
    • \n

      A film sample<\/strong> (100\u00d7100 mm or \u00d8100 mm) is clamped securely using pneumatic or manual fixtures.<\/p>\n<\/li>\n

    • \n

      A pendulum<\/strong>, fitted with a hemispherical impact head<\/strong> (usually \u00d838.1 mm), swings from a predetermined height.<\/p>\n<\/li>\n

    • \n

      The pendulum hits the center of the specimen, and the energy absorbed<\/strong> is calculated from the difference in swing angle before and after impact.<\/p>\n<\/li>\n<\/ul>\n

      Energia m\u00f5\u00f5tmine:<\/strong><\/p>\n

      The result, in joules, is normalized against the film\u2019s thickness to determine its specific resistance to perforation<\/strong>. The goal is to ensure that the pendulum impact resistance test<\/strong> reflects realistic material performance.<\/p>\n

      Visual Inspection:<\/strong><\/p>\n

      In addition to numeric values, the appearance of the perforation<\/strong> is also noted\u2014whether the film tears cleanly, stretches, or shatters.<\/p>\n

      \n

      Why Use Film Pendulum Impact Testing?<\/h2>\n

      Film impact resistance testing<\/strong> is essential for materials used in high-performance applications. It is widely adopted in industries such as:<\/p>\n

        \n
      • \n

        Paindlik pakend<\/strong>: Ensures pouch, sachet, and blister durability during transport.<\/p>\n<\/li>\n

      • \n

      • \n

        Autot\u00f6\u00f6stus ja elektroonika<\/strong>: Evaluates composite membranes and protective films.<\/p>\n<\/li>\n<\/ul>\n

        Manufacturers must ensure that materials will not fail under mechanical stress. This makes pendulum impact resistance tests<\/strong> a standard quality control procedure in R&D and production.<\/p>\n

          How to Perform a Film Impact Resistance Test Based on NF T54-116<\/h2>\n

          1. Proovi ettevalmistamine<\/strong>
          Cut 10 test specimens (100\u00d7100 mm or \u00d8100 mm). Condition them at 23\u202f\u00b1\u202f2\u00b0C and 50% RH for at least 2 hours.<\/p>\n

          2. Machine Setup<\/strong>
          Calibrate the film pendulum impact tester<\/strong>, zero the pointer without a specimen, and select the appropriate impact head and counterweight.<\/span><\/strong><\/strong><\/p>\n

          3. Clamping<\/strong>
          Use pneumatic clamping to secure the specimen in a horizontal plane. Ensure pressure is stable and centered.<\/p>\n

          4. Impact Testing<\/strong>
          Release the pendulum. It strikes the specimen at a fixed energy level, and the energy absorbed<\/strong> during perforation is automatically recorded.<\/p>\n

          5. Data Recording<\/strong>
          Log the absorbed energy, calculate specific resistance (J\/\u03bcm), and observe the perforation type: brittle or ductile. Repeat for all specimens.<\/p>\n

          6. Report Results<\/strong>
          Your test report should include:<\/p>\n

            \n
