Rockwell Superficial Test Blocks

When testing thin materials, coatings, or case hardened surfaces, the shallow indentations of superficial Rockwell testing leave no margin for error. Our rockwell hardness superficial test blocks are engineered to be the unwavering benchmark for this exact reason. They provide the absolute certainty required to validate your instrument's performance, ensuring your measurements reflect the true properties of the surface treatment and not the influence of the substrate beneath.

Fully certified and traceable to NIST, these blocks are more than just reference materials; they are the cornerstone of a defensible quality program. Their use is fundamental for satisfying the stringent requirements of ISO and ASTM standards and passing rigorous audits. Investing in a premium set of rockwell hardness superficial test blocks is a direct investment in the integrity of your data and the confidence you have in your most sensitive quality assessments.
