IPS Testing regularly performs the Martindale Abrasion Test (ASTM D 4970, WSP 20.5) at its Appleton, Wisconsin-based physical testing laboratory.

In the Martindale test, the specimen is mounted fixture with a felt pad underneath. The abrasive material, determined by the customer, is secured in the sample holder. The weight desired is placed into position in the sample holder above the specimen. The instrument is then run for either a set number of cycles or to a specified endpoint. The Martindale tester can run 3 different patterns, an abrasion Lissajous figure, a pilling Lissajous figure, and a straight back and forth motion, which must be specified by either the customer or the test method. When finished the test is evaluated by a rating system to photo standards or the number of cycles to the specified end point is recorded.

Quality and durability are key considerations for any product. Comparing your product to another company's may be as simple as a single type of test -- abrasion testing. Abrasion testing measures the resistance of a selected material to wear and the removal of material from a surface as a result of mechanical action. In its essence, a piece of material is rubbed against another in a known pattern with a set amount of weight applied to create friction. The wearing of the sample can help determine several properties about the product, including:

=How well new bonding patterns, materials, or coatings in a nonwoven performed or what new patterns, materials or coatings may be used
=Longevity of a product, either in use or shipping depending on the parameters of the test
=How does the product compare to meeting government standards for its intended use

Both the Martindale and Taber tests (performed by IPS Testing) are designed to measure how well a material performs in terms of durability and its resistance to wear.
