Digital Vickers Microhardness Tester Consultancy

About Micro-Hardness Measurement:

The Vickers microhardness test procedure involves applying a controlled load with a diamond pyramid indenter to a material, measuring the indentation, and then calculating the hardness value. The process typically includes preparation of the sample, applying the load, and measuring the indentation's diagonal lengths.

Scope of Services

Testing will be carried out using a Digital Vickers Microhardness Tester as per applicable standards such as:
- IS 1501 (Part 1)
- ASTM E384
- ISO 6507
The laboratory shall provide hardness value (HV) along with test load and dwell time.
Microstructural interpretation is not included unless specifically requested.
