− Features

  • Full Hardness Range Pencils: Contains premium quality graphite pencils, covering the complete hardness spectrum from the softest to the hardest , enabling the determination of the exact point of film failure.
  • Standard-Conforming Sharpening: Includes a custom-machined aluminum pencil sharpener with integrated and reference marks, ensuring the graphite leads are precisely conditioned to the required length for standardized testing.
  • Abrasive Prep Material: A pack of grit sandpaper is included to properly flatten the pencil leads into a uniform cylindrical end-face before each test stroke, guaranteeing consistent contact area as per standard protocols.
  • Immediate Field Deployment: The kit is supplied complete with all necessary components and detailed instructions, allowing for immediate testing and assessment of paint, lacquer, and film hardness on-site.
  • Portable and Protected: Components are housed in a durable, protective case for organized storage and safe transport to various quality control inspection locations.

What is the core difference between the Basic Kit and the Complete Kit?

The Basic Kit is designed for manual operation, whereas the Complete Kit (PTKITC) includes a Pencil Cart that applies a consistent force at a angle for enhanced repeatability.

Does the Basic Kit contain the full range of test pencils?

Yes, the PT Basic Kit includes the complete set of graded graphite pencils, spanning the full (softest) to (hardest) scale.

How do I ensure the test is conducted according to ASTM D3363?

To ensure conformance, use the included custom sharpener to maintain the required lead geometry and the grit sandpaper to properly flatten the lead before making contact with the coating.

What types of coatings can be tested with this kit?

The PosiTest PT Basic Kit is suitable for evaluating the scratch resistance of a wide range of organic surface treatments, including paint, clear films, lacquers, and synthetic resins.

Is the hardness result quantitative?

The result of the pencil hardness test is a relative value (e.g., ) and is qualitative, indicating the hardest pencil that does not visibly scratch or penetrate the coating film
