Impact Resistance The ability of glass to withstand sudden impacts without breaking or causing injury. This is critical for safety, especially in environments exposed to accidental or deliberate impacts. 2. Pendulum Test The core testing method utilized in BS EN 12600 involves a pendulum apparatus that strikes the glass sample with a defined energy. This simulates real-world impact scenarios. 3. Resistance Classes Glass is classified into resistance categories based on the outcome of the impact test, e.g., whether it remains intact, develops cracks, or shatters. 4. Fracture Patterns The standard recognizes different fracture behaviors, such as: - No breakage: the glass withstands impact. - Cracking: the glass develops cracks but remains largely intact. - Shattering: the glass breaks into fragments. Understanding these patterns helps determine safety implications. --- Testing Procedures Under BS EN 12600 The impact testing methodology outlined in BS EN 12600 is rigorous, repeatable, and designed to simulate real-world impact scenarios. Here’s an extensive overview of the procedure: 1. Preparation of Test Samples Samples are cut to specified dimensions, generally as per the standard’s requirements, ensuring representative testing of the actual glazing unit or glass product. 2. Equipment Used - Pendulum impact tester: A calibrated pendulum with a specific mass and arm length. - Impact energy levels: Defined by the standard, typically ranging from low to high impact energies. 3. Test Execution - The glass sample is mounted securely in a frame that simulates its actual installation conditions. - The pendulum is released from a predetermined height, imparting a calculated impact energy to the glass. - Multiple impacts may be performed at different points on the sample to assess uniformity. - The process is carefully monitored, and the impact energy is increased incrementally until a failure pattern is observed. 4. Evaluation Criteria Post-impact, the sample is examined to determine: - Whether it remains intact or Bs En 12600 7 develops cracks. - The size, pattern, and severity of cracks. - Whether fragments pose safety hazards.
