EN 12891 Wear Resistance of Glass Waste
The European Standard EN 12891 specifies a method for determining the wear resistance of glass waste materials. This test is crucial in assessing the durability and potential for recycling of glass waste products. The standard applies to various types of glass, including container glasses, flat glass, and other glass waste materials that may be recycled into new applications.
The test involves a series of steps designed to simulate real-world conditions under which recycled glass might be used in construction or manufacturing processes. It is particularly important for quality managers, compliance officers, R&D engineers, and procurement personnel working within the waste management and recycling sector to ensure that recycled materials meet stringent performance criteria.
The testing procedure outlined in EN 12891 involves subjecting samples of glass waste to a controlled abrasion process using an abrasive wheel. The wear resistance is measured by observing the depth of the scratch or indentation left on the surface of the sample after it has been exposed to the abrasive action. This measurement provides valuable insights into the potential durability and performance of recycled glass materials.
The standard also includes detailed guidelines for sample preparation, which are critical for obtaining accurate test results. Specimens must be cut from larger pieces of glass waste in a manner that ensures representativeness of the material being tested. The specimens should be free from defects and should have dimensions suitable for the testing apparatus.
| Sample Preparation | Test Specimen Dimensions (mm) |
|---|---|
| Cut from larger pieces of glass waste | 100 x 50 x 2 mm |
| No defects allowed | Uniform thickness ±0.1 mm |
The testing apparatus used in EN 12891 includes an abrasion tester designed to apply a controlled force and speed to the abrasive wheel. The specimen is placed on the fixture of the tester, and the test begins by rotating the abrasive wheel at a specified rpm while applying a constant load. The duration of the test is typically set according to the expected wear conditions in real-world applications.
The wear resistance is quantified by measuring the depth of the scratch or indentation on the specimen's surface after the abrasion process has concluded. This measurement is taken at multiple points along the length and width of the sample, ensuring an accurate representation of the entire surface. The average value of these measurements is used as the final result.
Accurate reporting of test results is essential for compliance with regulatory requirements and internal quality control processes. Eurolab provides detailed reports that include all relevant data from the testing process, such as specimen dimensions, applied load, test duration, and the measured wear resistance values. These reports are invaluable tools for decision-making in waste management and recycling operations.
| Test Parameters | Values |
|---|---|
| Abrasive Wheel RPM | 300 ± 5 rpm |
| Applied Load | 10 N ± 0.2 N |
| Test Duration | 60 seconds ± 0.5 seconds |
