UCI (Ultrasonic Contact Impedence) - MIC .The TeleBrineller is a portable device capable of making hardness measurements of metals in the field. This method uses a tungsten carbide ball indenter and standard hardness bars. By comparing impressions made simultaneously on the standards and the sample, the hardness of an unknown can be determined with reasonable accuracy.Place Hardness tester perpendicular to sur-face to be tested. Press down until give is felt in spring loaded anvil. Failure to press down may damage nose cone. Strike with 2 to 5 pound hammer. Follow instructions for use of Telebrineller to determine hardness of material. bar holder for next hardness test. ball with flat nose punch, drive new ball3.2 Conducting the Test. Positioning the Sample: Secure the material sample in the testing machine.; Selecting the Indenter: Choose the appropriate ball diameter based on the material hardness.; Applying the Load: Gradually apply the specified load using the machine.The load should be maintained for a predetermined dwell time, usually between 10 to 15 seconds.
The resulting Brinell Hardness Numbers are rounded to the nearest standard BHN occurring at a .05mm interval in Ta-ble I of ASTM Standard E10 and this BHN is etched on the end of the bar. Please note the accuracy of any test made with the Telebrineller is dependent upon the relative hardness of the test bar and the test piece. Some tests, like the Vickers hardness test, can be used on a macro scale as well as a micro scale. The loads required are listed in Table 1 below: Table 1: Different Hardness Test Methods and Their Corresponding Loads. Method Load Range Standard; Method. Brinell. Load Range. 1 kgf–3,000 kgf. Standard. ASTM E10, ISO 6506. Method.Most Popular Bar Hardness Ranges are: 170, 188, 194, 200, 207, 212, 217, 223, 229, 235, 241 Complete list of manufactured TeleBrineller Bar Hardness Ranges:
Metal hardness testing is a crucial aspect of various industries, including manufacturing, aerospace, automotive, and construction. It helps ensure the quality and reliability of metal components used in these sectors. When it comes to conducting hardness tests, two primary types of testers are commonly used: portableThe test bars which are the core of this system, are calibrated to a uniform hardness of +/- 3% of the labelled BHN. Hardness of the bars is measured by equipment whose accuracy is certified traceable to the National Standards Institute. The Telebrineller microscope is by Leica. Readings may be made within 0.05 mm. Waterproof:Set includes: 5 brinell bars (156, 207, 255, 331, 477), microscope w/pen light, computer, bar holder, calculation pad, and carrying case The Telebrineller System The Telebrineller system is a major achievement in quality assurance. .
The Leeb Hardness Test, also known as the rebound hardness test, measures hardness by analyzing the rebound of an indenter, rather than the size of an indentation. It is portable and ideal for on-site testing of large and heavy components, offering a non-destructive method that causes minimal damage to finished parts and coatings.Please note the accuracy of any test made with the Telebrineller is dependent upon the relative hardness of the test bar and the test piece.
