| Application Area | Specific Examples | Why Tear Resistance Matters | | :--- | :--- | :--- | | | O-rings, sealing lips, gaskets | To resist tearing when pulled over sharp threads, edges, or grooves during installation and prevent seal failure. | | Automotive | Rubber profiles, hoses, weather strips | To withstand constant bending, vibration, and exposure to sharp edges, preventing crack propagation and failure under dynamic loads. | | Industrial Components | Molded parts, diaphragms, conveyor belts | To ensure durability under cyclic loading and potential impact damage, maintaining performance over the product's lifespan. |
DIN ISO 34-1 now specifies :

: For industrial components like O-rings , seals, and gaskets, this value is vital because it determines how a part will behave if it is slightly damaged during assembly or stressed by sharp edges.
Searching for a is a common first step, but it is the wrong step for any professional application. The standard is dead. Using it could cost you time, money, and credibility. | | Automotive | Rubber profiles, hoses, weather
