Description
The TQC Sheen Spring Loaded Roller is a precision accessory designed to improve the accuracy and repeatability of dust testing on prepared surfaces. Used in combination with the Dust Test Kit, this roller ensures that adhesive dust test tape is applied with a consistent and controlled force, eliminating variations caused by manual pressure.
The instrument uses a spring mechanism combined with a rubber roller and multiple wheels to apply a fixed load of approximately 44.13 N (4.5 kg) across the tape surface. This guarantees uniform adhesion of the tape to the substrate, which is essential for reliable dust particle measurement.
By removing operator-dependent variability, the Spring Loaded Roller significantly enhances test consistency, making it ideal for both laboratory and field inspections where standardised results are required.

Why Use a Spring Loaded Roller
When performing dust tape tests manually, variations in applied pressure can lead to inconsistent results. The Spring Loaded Roller solves this by:
- Applying a constant, standardised force
- Reducing human error during testing
- Improving reproducibility between operators
- Ensuring compliance with international standards
This makes it an essential accessory for professional coating inspection and quality control.
⸻
How It Works
- Apply the dust test tape to the prepared surface.
- Position the spring loaded roller centrally over the tape.
- Press down until all wheels are in full contact with the surface.
- Move the roller back and forth over the tape (typically 2–3 passes).
- The roller ensures a constant force is applied across the entire tape area.
- Remove the tape and proceed with visual evaluation using the comparator.

Manufacturing and Standards
The TQC Sheen Spring Loaded Roller is manufactured by TQC Sheen, part of Industrial Physics, and is engineered for reliable surface cleanliness testing in coatings inspection.
The instrument supports testing according to internationally recognised standards:
• ISO 8502-3 — Assessment of dust on surfaces prepared for painting
This ensures accurate, repeatable and standardised dust contamination measurements prior to coating application.
