Biuged BGD 526 Wet Abrasion Scrub Tester

The Biuged BGD 526 Wet Abrasion Scrub Tester is a precision instrument designed to evaluate the washability, scrub resistance, and stain‑removal durability of coatings under controlled, repeatable conditions. It simulates real‑world wear caused by brushes, sponges, and cleaning actions, making it essential for interior paints, high‑traffic coatings, and detergent‑performance testing. It conforms to major international scrub‑test standards. The tester reproduces the mechanical wear that coatings experience in daily use—especially in areas prone to soiling such as kitchens, corridors, and workspaces. A coated test panel is mounted beneath a moving scrub head fitted with a brush, sponge, or abrasive pad. The instrument performs repeated scrubbing cycles under controlled speed and pressure until:

• the coating fails,

• a defined number of cycles is reached, or

• a specified cleanability threshold is achieved.

The BGD 526 provides consistent, reproducible results for washability, stain resistance, and detergent‑performance evaluation.

Key Features

Standards‑Compliant Operation

Conforms to major scrub‑test standards, including:

• ASTM D2486

• ASTM D3450

• ASTM D4213

• ASTM D4828

• DIN EN 11330

• EN ISO 11998

ensuring globally comparable washability and scrub‑resistance results.

Adjustable Scrub Speed

Scrub speed can be set to meet the requirements of different standards and coating types.

Automatic Cycle Counter

A four‑digit counter automatically stops the machine when the preset number of cycles is reached, ensuring repeatability and preventing over‑scrubbing.

Multiple Scrub Media Options

Compatible with a wide range of scrub heads and accessories, including:

• Nylon brushes

• Hog‑bristle brushes

• Abrasive pads

• Sponges

• Plastic test panels

• Brass shims

These allow testing of different coating systems and standards.
