DDL Inc. now offers Sutherland Rub Testing to determine the durability and abrasion resistance of printed materials that may be impacted by shipping conditions, temperature and humidity, time, and many other variables. Sutherland Rub Testing is used to meet the requirements of testing standards such as ASTM’s D5264 standard for abrasion resistance of printed materials.
“The Sutherland Rub Test is the industry standard used to determine the amount of scuff or abrasion damage that may occur to printed materials during shipment, storage, or handling. This damage could result in a significant degradation in the appearance and legibility of label information,” said Amy Peterson, Lab Manager, DDL Product & Materials division. “The addition of this test complements the wide range of other package, materials and producttesting DDL already offers its customers to help comply with ASTM, ISTA, ISO and other accepted industry standards.”
The Sutherland Rub Test is a simple procedure that can be used to compare different inks, coatings, laminates and substrates for their comparative abrasion resistance or to establish performance benchmarks.The legibility of printed materials is very important for packaging of medical device and pharmaceutical products in particular.The 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 one another at a controlled speed for a predetermined number of cycles. Once the rubbing stops the samples are visually inspected to see if the ink has worn off or not.
