1.4 Conditions for hardness testing
You will find all the essential instructions for operation
of the MIC 10. In addition to this there are a series of
factors which affect the test results. Due to the fact
that a description of these factors would extend be-
yond the scope of this manual, the three most import-
ant conditions are as follows:
•
training of the operator
•
knowledge of the special technical requirements
and limits
•
selection of the suitable test setup
Training of the operator
For reliable application of a hardness tester suitable
training in the field of material testing is required.
Suitable training means, for example, suitable know-
ledge about:
•
hardness testing on metallic materials.
•
effects of material properties, especially the struc-
ture, on the hardness test and the selection of a suit-
able hardness testing setup connected with it.
•
the problems of comparability of different hard-
nesses such Vickers, Rockwell and Brinell. Also
refer to the information given in the Appendix.
•
the effects of surface treatment on the hardness
value.
•
the effect of the test load, and the size of the indent
connected with it, on the determined hardness
value.
Please read also the instructions in chapter 1.5.
)
Attention:
Insufficient knowledge of the above mentioned
fields can cause wrong test results and could
have unforseeable consequences.
