Bennewart Method: EN Sole Flexing Tester GT-KB06 A shoe sole may wear out and crack or break due to the strain generated by the flexing action of the foot. Cracking or fracturing can also occur from sharp edges cutting notches and punctures, which will gradually turn into cracks during continuous flexion. It is therefore important to test the flex-crack resistance of shoe soles, and the Bennewart ...
Understanding Sanitary Napkin Water Absorbency Tester GT-CN20 In the sanitary products industry, the absorbency of sanitary napkins is one of the most critical quality metrics. In order to ensure that sanitary napkins can meet the needs of consumers and comply with the relevant standards, manufacturers and third-party testing organisations need to evaluate them with the help of professional testin...
The Elmendorf Tearing Strength Tester: A Complete Guide The Concept of Tear Strength Individual yarns in a fabric tear under stress concentration in the remaining fabric, which is referred to as the tear phenomenon of the fabric. For example, when a fabric is grabbed by an object, the local yarns will be forced to tear. Or part of the fabric is fixed and torn into two halves. Typically, tear perfo...
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...
ASTM D1777 Textile Thickness Gauge - A Comprehensive Guide In the quality control and performance evaluation of textile materials, precise thickness measurement plays a pivotal role. It not only affects the product's visual texture but also directly impacts the durability, warmth retention, and comfort of textiles. To standardize and unify textile thickness testing methods, the American Society fo...
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...
