Paper dust meter
This article outlines the features, standards, and operating principles of paper dust testers, essential tools for assessing surface cleanliness in paper, film, and nonwovens. These instruments quantify dust particles, spots, and imperfections, ensuring compliance with quality control standards.
Applicable Standards
The tester conforms to global industry standards:
ISO: ISO 16762 (Paper/board), ISO 15311 (Nonwovens)
TAPPI: T 430 om-18 (Particle Analysis)
GB/T: GB/T 1541-2013 (Paper/board)
Main Parameters
| Parameter | Specification |
|---|---|
| Measurement Area | A4 (210×297mm) or Customizable |
| Particle Resolution | ≥0.1mm² (Detects particles >0.05mm) |
| Detection Range | 0.01-5mm² (Adjustable Threshold) |
| Accuracy | ±5% (Particle Size/Count) |
| Scanning Speed | <10 seconds/sheet |
Working Principle
The tester uses a high-resolution imaging system with LED backlighting to scan samples. Advanced algorithms analyze captured images, identifying particles based on size, contrast, and reflectivity. Results are displayed as counts, sizes, and distributions.
Test Principle
Particles are classified by:
Area: ≥0.01mm² (ISO 16762)
Contrast: ≥15% (relative to background)
Morphology: Non-fibrous debris (inks, adhesives)
Applications
Suitable for paper mills, converters, and QA labs, the tester ensures compliance with hygiene, packaging, and printing standards. Its automated analysis reduces human error and accelerates inspection workflows.
This guide provides technical clarity for selecting and utilizing dust testers, supporting informed decisions in quality control and process optimization.
