Brinell Hardness Testing Unit

INTRODUCTION

Material testing allows determining strength of materials, verifying their properties and establishing their behaviour under external influences.
Shape and dimensions of a body, specific weight and density, humidity content, etc. are generally determined with physical tests, whereas strength, elasticity and plasticity, ductility, tenacity and fragility, etc. are determined with mechanical tests.
The hardness test is, together with the tension test, one of the most used in metals selection and quality control. Intrinsically, hardness is a surface condition of the material and it does not represent any fundamental property of the mass.
Hardness test is simple, highly efficient, since it does not destroy the sample, and especially useful to evaluate properties of the different microstructural components of the material.
The Brinell Hardness Testing Unit, “EEDB” allows Brinell hardness measurement on different materials.

EXERCISES AND PRACTICAL POSSIBILITIES

1. To learn how to use the instrumentation to perform hardness tests.
2. Study and familiarization with Brinell hardness test equipment.
3. Brinell hardness measurement on different materials.
4. To observe the behaviur of diverse materials under different loads applied.
5. To know the types of standard test pieces for these types of tests.
6. To know the types of standard indenters for these types of tests.
