Branson Krautkramer MIC 10, User Manual

Page: 98 / 146

Measurement method UCI method (Ultrasonic Contact Impedance) with Vickers diamond
Test load Handheld probes MIC 201-A (10 N), MIC 205-A (50 N), MIC 2010-A (98 N)
Indentor Diamond pyramid according to Vickers, roof angle 136°
Test materials Metallic materials
Basically, measurements are also possible on glass and ceramics.
Please contact your Krautkrämer service agent.
Measurement tolerances Max 5% tolerance in the Vickers hardness range from 200 HV to 900 HV.
Max
±
3.6% deviation from the average measurement value to the value of
the hardness reference plates.
These deviations are determined from 5 single measurements using the test
support MIC 222.
With handheld measurements greater deviations are possible. Deviations in
the measurement result caused by plate vibration can be reduced by coupling.
The error data are related to the total error (instrument plus hardness refer-
ence plate)
For more information refer to chapter 9.1
Measurement/Conversion range Vickers: 20 - 1740 HV
Rockwell B: 41.0 - 105.0 HRB
Rockwell C: 20.3 - 68.0 HRC
Brinell: 76.0 - 618.0 HB
Tensile strength: 255.0 - 2180.0 N/mm
2
(only with the 10 kgf probe connected)
The conversion is made according to DIN 50150 or ASTM E 140.
