Name of the equipment: Vickers Hardness Tester-Digital type Make & Model: Matsuzawa Co. Ltd, Japan VMT X7S I-Stem Registration ID-   3224876 Category of Instrument Hardness Tester Types of Analysis / Testing Vickers Hardness Testing Application: Measure the Hardness of various Materials Research and development in material science Description of Instrument An instrument used to measure the hardness of materials by creating a small, diamond-shaped indentation on the material's surface and then measuring the diagonals of the indentation. The device applies a known force, typically between  1 kg and 50 kg, using a diamond indenter in the shape of a square-based pyramid. The hardness value, expressed as Vickers Hardness Number (HV), is then calculated based on the indentation's dimensions and the applied force.

 1. Type of Sample Required

• Material State: Solid, homogeneous material
• Shape: Preferably flat, polished, and stable under load
• Minimum Surface Area: Must fully accommodate the indentation and microscope viewing — typically ≥10 mm × 10 mm
• Thickness:
• Minimum: 1 mm (to prevent distortion or substrate influence)
• Recommended: ≥3 mm for higher loads (>5 kgf)
• Maximum: As per test setup, generally ≤10 mm for small lab-scale machines
• Quantity:
• Single sample per test condition
• More if multiple tests or repeatability is required

2. Pre-Preparation of Sample (by User)

To ensure accurate and consistent results:

• Flat Surface: The test surface must be flat and perpendicular to the indenter axis.
• Polishing:
• Polish to a mirror-like finish (up to 1 µm diamond paste or finer)
• No surface scratches, pits, or oxidation
• Cleanliness:
• Free from oil, dirt, or oxidation
• Clean with ethanol or acetone before submission

3. Guidelines for Sample Submission

• Labeling: Clearly label each sample with an ID or code using permanent marker or an attached label (not on the test surface).
• Packaging:
• Use non-abrasive packing material (e.g., foam or soft cloth)
• Avoid stacking bare samples together
• Test Requirements to Provide:
• Load required (e.g., 1 kgf, 5 kgf, etc.)
• Number of indentations per sample
• Specific location(s) if applicable
• Material information (alloy, treatment history, etc.)
• Delivery Note: Include a document with:
• Contact details
• Test details
• Sample IDs and quantity
