Professional LS falling sand abrasion tester for aluminum coating manufacturers: quantifies fluorocarbon, paint and varnish wear resistance per GB/T5237.5 standard.
LS Falling Sand Abrasion Tester for Coating Wear Resistance
Description
Falling Sand Abrasion Tester LS Description — Coating Wear Resistance Testing Solution
The Model LS Falling Sand Abrasion Resistance Tester is a standards-compliant coating wear resistance testing machine designed for organic coatings, varnishes, and fluorocarbon-coated aluminum alloy architectural profiles per GB/T5237.5—2000. Standard sand falls freely through a guide tube from a set height to abrade the coating until the substrate appears. Abrasion resistance is quantified by the volume of abrasive per unit thickness—making it an essential quality control instrument for coating manufacturers, third-party inspection agencies, and R&D labs.
Key Features & Highlights
- Standard-Compliant Falling Sand Testing: Engineered for highly accurate, repeatable abrasive wear testing conforming to GB/T 5237.5-2000 and ASTM D968.
- Precise Sand Flow & Height Control: Features a calibrated guide tube with strict vertical alignment to ensure consistent, repeatable test conditions.
- Auto Counting & Preset Shut-Off: Automatically halts operation when the sand is depleted or the pre-configured volumetric target is reached, preventing test errors.
- Quantitative Wear Evaluation: Measures volumetric abrasive consumption (Liters) per unit coating thickness, delivering clear and objective test data.
- Heavy-Duty Ergonomic Design: Built with an integrated stable frame, precision funnel assembly, and an adjustable 45° specimen holder for smooth lab operations.

Application Fields
This tester is widely utilized by QA/QC laboratories, third-party inspection agencies, and research institutes across critical manufacturing sectors:
Architectural Aluminum Profiles
Fluorocarbon (PVDF) and powder coating inspection for building materials and extrusion profiles.
Automotive & Transportation
Surface coating durability testing for automotive bodies, exterior parts, and transport equipment.
Aerospace & Industrial Coatings
High-performance protective finish evaluation for critical industrial and aerospace components.
QA/QC & Research Labs
Widely utilized by quality assurance laboratories, third-party inspection agencies, and R&D research institutes.
Q: What standard does the LS abrasion tester comply with?
A: It conforms to the Chinese National Standard GB/T5237.5—2000 for abrasion resistance of fluorocarbon coatings on aluminum alloy architectural profiles, using the falling sand method.
Q: How does the falling sand abrasion test work?
A: Standard sand falls freely through a guide tube from a set height onto the coated sample, abrading the surface until a 4 mm substrate exposure appears. Abrasion resistance is measured by the volume of sand (liters) consumed.
Q: What coatings can it test?
A: Fluorocarbon coatings, color paints, varnishes, spray coatings and related surface treatments on metal substrates.
Q: Is the test automatic?
A: Yes. The device features auto counting and stop — it halts automatically when the sand is depleted or a preset volume is reached, ensuring consistent, repeatable results.
