Biuged BGD 527 Wet Abrasion Scrub Tester

The Biuged BGD 527 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 ASTM D2486 and ISO 11998, the two most widely used scrub‑resistance 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 reciprocating scrub head fitted with a brush 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 527 provides consistent, reproducible results for washability, stain resistance, and detergent‑performance evaluation.

Key Features

Standards‑Compliant Operation

Conforms to:

• ASTM D2486

• ISO 11998

ensuring globally comparable washability and scrub‑resistance results.

Adjustable Scrub Frequency

Scrub frequency is fully adjustable from 5–95 cycles/min, allowing compliance with multiple test methods and coating types.

Automatic Cycle Counter

A 0–99,999 cycle digital counter automatically stops the machine when the preset number of cycles is reached, ensuring repeatability and preventing over‑scrubbing.

Standardized Brush System

Supplied with brushes meeting ASTM and ISO specifications:

• ASTM brush weight: 454 ± 10 g

• ISO brush weight: 135 ± 1 g

• Nylon bristles in a 5/4 pattern, extending 19 mm from the block.

Large Stroke Length

A 300 mm stroke length ensures uniform scrubbing across the entire test area.

Easy Sample Loading

Test plates (430 × 150 × 0.03 mm) can be quickly installed and removed for efficient workflow.
