Test Anvil for Rebound Hammer: Concrete Calibration Guide
The Schmidt Hammer Calibration Test Anvil can be used to check the calibration of concrete test hammers after every 1,000—2,000 impacts. The Schmidt Hammer Calibration Anvil has a solid steel 6in (152mm) diameter anvil with a hammer guide and hardened alloy steel rebound plate. It is compatible with equipment from various manufacturers, verifies operation and calibration for most manufacturers.
The Calibration Anvil is designed to meet the requirements of ASTM E 18. A wire brush for cleaning is included. Find everything you need for accurate and reliable concrete testing at Certified MTP including the NR Hammer, a rebar locator, and more.
The Schmidt Hammer Calibration Test Anvil Meets Test Methods: ASTM C 805 BS 1881-202
Understanding Calibration
Calibration is a crucial process in ensuring the accuracy and reliability of concrete test hammers. It involves verifying the proper operation and rebound energy of the test hammer to ensure that it is functioning correctly. Calibration is essential to maintain the accuracy of the test hammer’s measurements, which is critical in determining the compressive strength of concrete. A calibration anvil is a tool used to calibrate concrete test hammers, and it is designed to provide a consistent and reliable test surface for verifying the operation of the test hammer.
How to Use a Calibration Anvil
Using a calibration solid steel anvil is a straightforward process that requires careful attention to detail. First, ensure that the anvil is placed on a horizontal surface and that the test hammer is properly aligned with the anvil. Next, strike the test hammer on the anvil to determine its impact value. The impact value is measured in pounds per square inch (psi), and it is essential to ensure that the test hammer is calibrated to provide accurate measurements. It is recommended to check calibration after every 1,000 to 2,000 impacts to ensure that the test hammer is functioning correctly.
Calibration Anvil Maintenance and Troubleshooting
Regular maintenance is essential to ensure that the calibration solid steel anvil remains in good working condition. The anvil should be cleaned regularly using a wire brush to remove any debris or dust that may accumulate on the test surface. The anvil should also be stored in a dry, dustproof place to protect its rebound surface from collision. If the anvil becomes damaged or worn out, it should be replaced immediately to ensure accurate calibration. Troubleshooting common issues with the calibration anvil, such as inconsistent rebound readings, can be resolved by checking the anvil’s hardness certification and ensuring that it is properly aligned with the test hammer.
