The Original Sutherland Rub Tester is widely recognized as the benchmark for testing product durability and abrasion resistance. It has been utilized in various industries for over 70 years. Additionally, this instrument authored the ASTM Standard D.

The Sutherland rub tester operates as a motor-driven machine that accurately moves a weighted test strip for abrasion testing. Samples are rubbed against a printed specimen to evaluate the abrasion resistance of any printed material. The swift motion and repetitive strokes simulate the damage typically caused by shipping, handling, and other factors that may affect the printed material's quality.

Benefits of Using Sutherland Rub Tester

The original Sutherland rub tester, which authored the ASTM Standard D, also meets multiple standards such as TAPPI T830, ASTM F, FINAT FTM 27, and ASTM F. Companies employ it to assess printing application methods, wear testing, coating durability, and ink transfer. It mainly allows manufacturers to quantify the effects of abrasion, rubbing, and smearing on various materials.

The Sutherland Rub Tester offers several substantial benefits:

It Provides Accurate and Consistent Results

The Sutherland rub tester features a motorized arm that precisely rubs any printed material against standard abradants. This design ensures repeatable and consistent testing conditions, yielding reliable, accurate, and verifiable results.

It Is Designed for Longevity

This machine is robustly built to endure multiple heavy testing procedures. If you need a reliable device for durability testing of your products, the Sutherland Rub Tester is the industry standard.

Wide-Ranging Testing Capabilities

This versatile machine can test various printed materials, including films, laminates, coatings, and ink on substrates such as metal, plastic, cardboard, and paper.

It Is the Accepted Industry Standard

With over half a century of use in the printing industry, the Sutherland rub tester has become the go-to tool for testing product durability. The results derived from this instrument are widely recognized and accepted by regulatory agencies, suppliers, and manufacturers.

Rub Testing of Printed Labels

Manufacturers widely use the Sutherland rub tester for testing printed labels. It measures the scuff or abrasion that may occur when products are stored, handled, and shipped. Examiners can test labels at a specified speed that equates to a given period of use or storage.

Speed Settings

The Sutherland rub tester offers four distinct speed settings:

• First Speed Setting: This runs at 21 cycles per minute and is used for wet tests or any test that runs under five strokes.
• Second Speed Setting: This runs at 42 cycles per minute.
• Third Speed Setting: This runs at 85 cycles per minute.
• Fourth Speed Setting: This runs at 106 cycles per minute.

Key Specifications

The Sutherland rub tester boasts the following key specifications:

• Weight: Available in standard two and four-pound models, with various custom weights offered.
• Stroke Speeds: 21, 42, 85, 106 cycles per minute, programmable for a 21-stroke wet smear test, and configurable for custom speeds upon request.
• Maximum Number of Strokes: 999, with a set repeat mode.
• Heated Weights: Fully adjustable temperature range up to 500 degrees with a solid 304 stainless steel weight block and an included silicone pad specifically for the heated weight.
• Market Lifespan: Over 70 years and counting, with original machines still in use today. Upgrades for rub tester models are available upon request.

Sutherland Rub Test | ASTM D - DDL, Inc.

Abrasion damage to printed materials can happen during shipment, storage, handling, or by the end user. This damage can significantly degrade product appearance and the legibility of product information. For medical device and pharmaceutical products, clear label legibility is especially important.

Using the Sutherland Rub Test, our engineers measure the level of scuff or abrasion damage that printed materials may incur during shipment, storage, or handling. This test procedure can simulate the effects of continuous human use and dual-surface abrasion.

The Sutherland Rub Test is performed by attaching a label to the device, while a similar sample label is attached to a weight. The two samples are then rubbed against each other at a controlled speed for a preset number of cycles. Afterward, the samples are visually inspected to check for ink wear, helping to determine if the printing is durable enough to withstand typical handling and transportation conditions.
