แอสทาม D1424

Application Materials

แอสทาม D1424 is primarily applied to textiles. It is used to assess the tear resistance of woven fabrics, nonwoven fabrics, and other textile materials.

กระบวนการทดสอบ

The Elmendorf Tear Test involves placing the prepared specimen on the tester’s clamps. A pendulum, equipped with a blade, is swung to create a tear in the material. The energy required for the tear to propagate is measured, indicating the material’s tear strength. The test is repeated multiple times for accuracy.

การแปลผลการทดสอบ

Results are interpreted based on the energy required to tear the specimen. The higher the energy, the greater the material’s resistance to tearing, which reflects better tear strength. These values are reported in millinewtons (mN) and used to assess material performance in practical applications.
