Comprehensive Testing of Insole Materials: Thickness, Flexing Index, Abrasion, and Water Absorption/Desorption Insoles are a critical component in footwear that directly contacts the foot, providing comfort, support, and cushioning. To ensure the comfort, safety, and durability of insoles, a series of tests must be conducted. Testing Items The testing items for insoles primarily include the follow...
ISO 12945-2: Test Method for Surface Pilling Using the Martindale Abrasion Tester Pills are formed when fibers on a fabric surface migrate out and become entangled during wear. Such surface deterioration is generally undesirable, but consumer tolerance for a given pilling level depends on the garment type and fabric end-use. Introducing the ISO 12945-2:2020, a comprehensive standard that provides ...

How to Perform a Tensile Strength Test According to ASTM D412 ASTM D412 is the most common standard for determining the tensile properties of vulcanized (thermoset) rubber and thermoplastic elastomers. Compounds in this family are used to create a vast array of consumer goods such as tires, footballs, and rubber bands. What does it Measure? ASTM D412 measures the elasticity of a material while und...
A Complete Guide to ISO 37 Testing Solution This standard specifies methods for determining the tensile stress-strain properties of vulcanized rubber and thermoplastic rubber. Measurable properties include tensile strength, elongation at break, stress at a given elongation, elongation at a given stress, yield stress, and yield elongation. However, the measurement of yield stress and yield elongati...
