Principle
LEEB160C uses the Impact device for Hardness measurement. The Richter Hardness value is calculated by impacting the surface of the sample and measuring the rebound speed. The instrument automatically recognizes the type of Impact device and converts it to a variety of Hardness standards.
Applications
Heavy-duty workpieces, mold cavities, workpieces with small experimental space, bearings and other parts, on-site hardness testing of large parts and non-removable parts, Pressure Vessel, failure analysis of turbo-generator sets and their equipment, material distinction of metal material warehouses, Hardness testing of products in mass production process, Hardness testing of heat treatment such as annealing, tempering and quenching, casting testing
Standards
GB/T 17394.1-2014 "Metallic Materials, Richter Hardness Test, Part 1: Test Methods", GB/T 17394.2-2012 "Metallic Materials, Richter Hardness Test, Part 2: Hardness gauge inspection and calibrate", GB/T 17394.3-2012 "Metallic Materials, Richter Hardness Test, Part 4: Calibration of Standard Hardness Blocks", GB/T 17394.4-2014 "Metallic Materials, Richter Hardness Test, Part 4: Standard Value Conversion Table", Design Basis Standard: "Leeb hardness tester Technical Conditions" JB/T 9378-2001
Steps
1. Ensure that the surface of the sample meets the requirements: the surface temperature is less than 120 ° C, the asperity is not more than 1.6um, flat and smooth without oil pollution
2. Choose the appropriate support according to the weight and shape of the sample: no support is required for more than 5kg; support is required for 2-5kg; use the corresponding support ring for the curved sample
3. Select the appropriate Impact Device and install it
4. Boot and indication calibrated
5. Impact device perpendicular to the sample surface for measurement
6. Read or store measurement results
7. Optional on-site printing of test reports
Notice
• The surface of the sample needs to be exposed to metal Gloss, which is smooth and free of oil stains
• Specimen weight not less than 2kg, minimum Film thickness not less than 10mm
• For lightweight specimens, it needs to be tightly coupled with a sturdy support
• Support rings are required when the radius of curvature of the sample is less than 30mm (type D, DC, C, DL) or less than 50mm (type G)
• Sample surface temperature should not be too high, should be less than 120 ℃
The sample itself should be less than 30 Gauss magnetic
• Specimens with surface hardening layer should ensure that the depth of hardening layer meets the requirements
The test direction should be perpendicular to the coupling plane
• Avoid testing in situations that may cause deformation, bending, and movement of the specimen
