The included detergent and water recycling system ensures high efficiency.

This Wet Scrub Resistance Tester is the ideal wet abrasion test instrument to conveniently evaluate the Coating Surface Abrasion Resistance and Detergent Performance of samples in your laboratory for research and quality management.

This precision Wet Abrasion Scrub Tester is designed and engineered in accordance with international test standards including:

• ASTM D2486 (Standard Test Methods for Scrub Resistance of Wall Paints)
• ASTM D3450 (Standard Test Method for Washability Properties of Interior Architectural Coatings)
• ASTM D4213 (Standard Test Method for Scrub Resistance of Paints by Abrasion Weight Loss)
• ASTM D4828 (Standard Test Methods for Practical Washability of Organic Coatings)
• ISO 11998 (Paints and varnishes — Determination of wet-scrub resistance and cleanability of coatings)
• DIN EN 1330 (Non destructive testing. Terminology. List of general terms)
• DIN EN 53778 (Replaced by ISO 13300)
• BS 3900 F17 (Methods of tests for paints; determination of wet scrub resistance to cleanability of coatings)

Automatic Wet Scrub Resistance Tester – ASTM D 2486:

This professional Wet Scrub Resistance Tester is engineered in accordance with the test standard ASTM D 2486 to evaluate the scrub resistance of interior wall paint. To perform this Wet Scrub Resistance Test the paint is applied onto a black plastic panel. After curing the coated plastic panel is placed on the sample area of the Wet Abrasion Scrub Tester and is scrubbed with a nylon bristle brush with a load of 454 grams until failure occurs. The nylon brushes and test loads of 454 grams are available together with the automated Wet Scrub Resistance Tester to ensure a professional and precise test in accordance with ASTM D 2486.

Wet Scrub Resistance Test by Abrasion Weight Loss – ASTM D 4213 (Model QPI-2500 only):

This Wet Abrasion Scrub Tester is engineered in accordance with the test standard ASTM D 4213 to evaluate the wet scrub resistance by abrasion weight loss. When applying this test method the scrub resistance of samples is measured by the weight loss of the coating or paint film relative to the calibration panel. The sample and the calibration panel are scrubbed simultaneously. The abrasive parts and the calibration panel are available together with the automated Wet Scrub Resistance Tester to ensure a professional and precise test in accordance with ASTM D 4213.

Automatic Washability Scrub Tester – ISO 11998 /BS3900:

This Automatic Washability Scrub Tester is designed in accordance with the test standards ISO 11998 and BS 3900. The ISO and BS test standards describe the details of the washability scrub test. This Washability Scrub Tester uses special high quality pads with a load of 135 grams combined with a detergent to perform this standardized washability scrub test. The abrasive pads automatically complete 200 scrub cycles to perform this Washability Scrub Test. The evaluation of the wash/scrub resistance is done by calculating the loss of mass. The high quality abrasive pads and the test loads of 135 grams are available together with the automated Washability Scrub Tester to ensure a professional and precise test in accordance with ISO 11998 and BS 3900.

Automatic Wet Abrasion Scrub Tester – EN 13300 (replaces DIN 53778):

This Automatic Wet Abrasion Scrub Tester is engineered in accordance with the test standard EN 13300 (replaces the test standard DIN 53778). The Wet Abrasion Scrub Test area should be free of residuals. To evaluate the Wash Resistance a test with 1000 scrub cycles is required. To evaluate a the Scrub Resistance a test with 5000 scrub cycles is performed. This wet scrub abrasion test is performed with a hog bristle brush combined with a detergent supply system to continuously and precisely add the detergent. The evaluation is done visually. The natural bristle brushes and the test loads of 250 grams are available together with the automated Wet Scrub Resistance Tester to ensure a professional and precise test in accordance with the test standard EN 13300 (DIN 53778).
