RUGOTEST surface comparison plates — RUGOTEST set for visual and tactile roughness assessment

A RUGOTEST surface comparison plate set for straightforward assessment of surface roughness in inspection, calibration and production control environments.

• Comparison range Ra 0.05–12.5 µm
• Set of 30 hard-wearing plates
• ISO class N2–N10 calibration range
• For inspection and quality control

Ensure consistent roughness assessment across production

Surface finish decisions hinge on clear, reproducible references. With a Ra comparison span of 0.05–12.5 µm, this reference set provides a calibrated scale that helps operators and inspectors interpret profilometer readings or visual/tactile checks more reliably. The concept of Ra (arithmetical mean roughness) is standard in surface metrology: it summarises surface deviations in a single numerical value, making it easier to compare components and document conformity. Using a dedicated set of reference plates reduces ambiguity in acceptance criteria and supports consistent process control across shifts and locations.

Support traceable inspection workflows with ISO-class alignment

Conformity to ISO class N2–N10 makes the plates suitable as comparative standards within established quality-management frameworks. Classes N2–N10 designate graded levels of reference roughness that correspond to commonly used measurement and inspection tolerances; this alignment simplifies reporting and audit trails. The set functions as a physical reference for both tactile checks and as a visual aid when validating instrument outputs, improving reproducibility and traceability in incoming inspection, in-process checks and final quality assessment.

Integrate the reference set easily into daily inspection routines

The plates are supplied as a complete set designed for practical use in workshop and laboratory environments. Their layout and graduated roughness steps enable quick side-by-side comparisons that complement instrument measurements, accelerating decision-making on machining parameters, finishing steps or corrective actions.
