| longation % |
ASTM D 5035 |
Determines by percent the degree to witch a fabric will stretch before braking by grabbing and pulling in each direction. |
Length 62.45 %
Width 59.32 % |
|
| Tongue Tear |
ASTM D 2261 |
This test measures the capacity of a fabric to withstand the tearing force to propagate a single tear after its initiation. Origin of tear is initiated prior to testing. Results measure the force required to maintain a constant rate of tear in each direction after the initial tear. |
