Overview
The IPRE DC Impact device is a professional hardness testing equipment designed with an Impact energy of 11mJ, suitable for a variety of hardness of materials measurement. The device has an Impact device mass of 50g and a ball head diameter of 3mm, which can accurately measure materials with a maximum Hardness of 940HV and meet the testing requirements of different specimen weights and thicknesses.
Features
Impact energy of 11mJ, providing stable test performance
2. The ball head is made of tungsten carbide material, with Hardness up to 1600HV to ensure durability
3. Impact device diameter 20mm, length 86mm, compact and portable
4. Measurement modes with minimum weight from 0.05kg to > 5kg
5. The minimum thickness of the hardened layer is only 0.8mm, which is suitable for thin layer material testing
6. Indication Errors and Repeatability Meet Standards to Ensure Measurement Accuracy
Principle
The DC-type Impact device forms a Cedar on the surface of the ball head Impact specimen by releasing Impact energy, and calculates the Hardness value based on the Cedar diameter and depth. The device uses the Impact energy of 11mJ and the ball head tungsten carbide material to generate specific Cedars under different Hardness conditions, thereby deriving the Richter Hardness value and realizing fast and non-Destructiveness hardness testing.
Applications
Metal hardness of materials testing, industrial quality control, material research and development testing, machinery manufacturing
Standards
Standard Richter Hardness Block Hardness: 760 +/- 30HLDC, 530 +/- 40HLDC
Steps
1. Measurement mode according to the weight of the specimen: direct measurement (> 5kg), stable support (2-5kg) or dense coupling (0.05-2 kg)
2. Ensure that the surface roughness of the specimen does not exceed 1.6 μm
3. For thin specimens, the thickness should be at least 5mm and tightly coupled
4. Align the Impact device vertically to the surface of the specimen for Impact testing
5. Read and record Hardness indication, check error range
Notice
• Specimen surface roughness should be controlled within 1.6μm to ensure measurement accuracy
• For specimens with a weight of 0.05-2 kg, they must be fixed by dense coupling
• When the minimum thickness of the specimen is 5mm, it needs to be tightly coupled to avoid test errors
• The hardened layer thickness should not be less than 0.8mm, otherwise it may affect the test results
• Impact device vertical impact measurement to avoid data deviation caused by tilt
Periodically calibrate device to maintain Indication Error within +/- 10HLDC
