How the Paper Tearing Tester Works

  • Test Process: The SLD-02 Paper Tearing Tester operates with a precise mechanism that delivers standardized tear testing:
    1. A cutting knife creates a 43mm slit from the far edge of the sample.
    2. The pendulum mechanism, once released, uses gravity to propagate the slit, tearing the sample along the remaining length.
    3. The energy lost during this process is measured and used to calculate the sample’s average tearing force, yielding a reliable tear resistance value.

Compliance with Major Standards (Including ASTM D689)

  • Overview of Standards: The SLD-02 Tear Tester complies with a range of international standards, ensuring it meets rigorous testing requirements:
    • ASTM D1922: Testing for tear resistance of plastics.
    • ASTM D1424: Standard for measuring tear resistance of textiles.
    • ASTM D689: A specific standard for measuring tear resistance of paper and paperboard, essential for packaging quality control.
    • ISO 6383 & ISO 1974: International standards for tear strength.
    • TAPPI T414: Paper tear resistance testing standard, widely used in the paper industry.
  • Focus on ASTM D689: ASTM D689 is a key standard for tear resistance measurement in paper and cardboard materials, ensuring that products like packaging meet quality requirements. This standard outlines specific methods for testing tear strength, enhancing accuracy and reliability, particularly in quality control applications. By meeting ASTM D689, the SLD-02 provides results you can trust, facilitating compliance with industry norms.
