How easily a fabric tears, breaks, holds up to weight, stretches, etc, can all impact the suitability to the end application. Physical Properties testing is important to ensure the textile being used will hold up to the requirements of the environment and application of the fabric. Depending upon the requirements there are many available tests to measure suitability and performance potential.

Brush Pill ASTM D3511
Measures the propensity of a fabric to form pills (bunches or balls of tangled fibers which are held to the surface by one or more fibers). Specimens are brushed with a nylon bristle brush for 4 minutes to create fuzzing and then rubbed face to face for 2 minutes to create pilling.
Lead time: 3-5 days
Yardage Required: 18” x Full
Breaking Strength ASTM D5034
Measures the maximum force applied to a material to force a rupture.
Lead time: 3-5 days
Yardage Required: 18” x 36”
Coating Adhesion ASTM D751
Determines the force required to separate a chemical coating from the backing material.
Lead Time: 5-7 days
Yardage Required: 36” x 36”
Hydrolysis ISO 1419, Method C
Determines the ability of a polyurethane material to withstand the environmental effects of high humidity or exposure to wet conditions. Visual evaluations for cracking, peeling or delamination are made after placing specimens in an environmental chamber at 158°F and 95% relative humidity for week intervals. Alternately, coating adhesion, flex resistance and / or abrasion can be evaluated before and after exposure.
Lead time: 5 weeks / Yardage Required: 24” x Full
Martindale Pilling ASTM D4970
Measures the propensity of a fabric to form pills (bunches or balls of tangled fibers which are held to the surface by one or more fibers). Specimens rub face to face for 100 interval movements.
Lead Time: 3-5 days
Yardage Required: 9” x Full
Stretch + Set SAE J855
Measures the stretch resistance and recovery ability of a fabric when subjected to 25 pounds of force.
Lead Time: 3-5 days
Yardage Required: 18” x 36”
Seam Slippage ASTM D4034, D434/D3597
Measures the displacement of one or more yarns from the original position, causing differences in alignment or spacing or both by applying an increasing amount of force to a seam.
Lead Time: 3-5 days
Yardage Required: 24” x 36”
Tear Strength: Tongue Method ASTM D2261
Measures the actual tearing strength of a fabric by partially slitting a specimen to resemble pants and pulling with equal force in opposite directions on the two “legs.”
Lead Time: 3-5 days
Yardage Required: 18” x 24”
Tear Strength: Trapezoid Method ASTM D5733
Measures the force required to propagate a single rip tear starting from a cut in the fabric; specimens are tested in accordance with the trapezoid procedure whereby specimens are clamped in the jaws along opposite sides of the trapezoid marked on the specimen.
Lead Time: 3-5 days
Yardage Required: 18” x 36”
