Rebound Hammer Calibration Anvil Test Anvil for Rebound Hammer for Calibrating Concrete Rebound Hammers, Mortar Rebound Hammers,Brick Rebound Hammers,Etc

Introduction 1. Test anvil is the excellent instrument for assessing test hammer. 2. Test anvil is made from the best steel and especial tool steel. Contact area between anvil core and anvil body get excellently polished, and the rigidity of anvil core is HRC58~62 3. Test anvil must be located on horizontal ground, take test hammer operation on it and check the rebound value, qualified concrete test hammer will get a average rebound value of 80±2 on test anvil, qualified mortar test hammer will get a rebound value of 74±2. 4. The test anvil, as a calibration instrument, after each 5000 or 8000 test, the test surface can be polished and then continue using, but the rigidity of core must be HRC58~62, or abolish it. 5. Test anvil usually stored in dry dustproof place, protect its rebound surface from collision.

• This testing anvil is an inspection tool used to calibrate rebound hammers for concrete, mortar, bricks and similar materials.
• The parts of this anvil are made of steel and tool steel. Anvil core and anvil body of the mating surface [Mohs taper 4] by grinding, anvil core surface hardness of HRC58-62.
• The steel anvil is generally placed on the horizontal surface to calibrate the rebound meter, rebound meter vertical down for the bounce test, calibrate the rebound meter rate value.
• Concrete rebound meter in the anvil for the average rate of the ballistic test rebound value of [N] = 80 ± 2; Mortar rebound meter in the anvil for the average rate of the ballistic experiments for [N] = 74 ± 2.
• The anvil as a test tool, was hit 5000 times -8000 times after the test, the anvil core along with the anvil body in the plane grinding flat reuse, but the anvil core hardness still need to maintain HRC58-62, otherwise shall not be used.
• The testing anvil is usually kept in a dry and dustproof place to prevent rust and corrosion, and the surface of the ballistic test should not be bumped at will to test the standard state of the tool.
