Metallic materials - Wechsler hardness test
Part 1. Test methods
1 Scope
This part of GB/T 32660 specifies the test principle, test apparatus, specimen, test procedure, test results
Processing and test report.
This part applies to the Wechsler hardness test of metal materials, the measured value range is equivalent to Rockwell hardness 53.0HRB ~ 92.2HRB,
28.0HRE to 110.0HRE and 30.2HRF to 98.5HRF.

3 test principle
Will be specified shape of the steel pressure needle, under the action of a certain test force pressed into the sample surface, with the pressure into the depth of the pressure to represent the material
Hardness, defined 0.0125mm The press depth is a Wechsler hardness unit. The hardness of the material is related to the depth of the press, and the superficial pressure is applied
The higher the degree, the other is low, the expression see (1).
HW = 20-L/0.0125 (1)
Where.
HW --- Wechsler hardness symbol;
L - the depth of the needle pressed into the specimen in millimeters (mm).
4 Hardness value representation
When using aluminum mold with A-type hardness tester with HWA, the use of B-type hardness tester with copper alloy and mild steel with HWB table
, The use of C-type hardness tester with pure HWC said, the symbol before the value of the hardness value. Test the aluminum with A-type durometer
Gold, the hardness symbol HWA in the A can be omitted, can be expressed as HW.
Example.
11HWA or 11HW indicates that the Wechsler hardness value of the aluminum alloy is 11 using an A-type durometer.
9HWB indicates the use of B-type hardness tester measured copper alloy and soft steel Webster's hardness value of 9.
10HWC indicates that the Hardwood hardness value of pure copper is 10 by using a C-type durometer.
5 test equipment
5.1 hardness tester
The instrument used for the test is the Wechsler durometer. The hardness meter shall comply with the provisions of GB/T 32660.2.
