ASTM D3198

Standard Test Method for Application and Removal Torque of Threaded or Lug-Style Closures

مواد الاختبار

According to ASTM D3198, the primary materials tested are closures and containers, specifically for assessing the torque strength of sealing closures. These may include bottle caps, jar lids, or other types of screw-on seals used in various industries like food, pharmaceuticals, and beverages.

In the test, a torque tester is used to apply a controlled rotational force to the closure. The closure is attached to the container, and the tester measures the torque required to open or seal the container. This process ensures the closure’s ability to maintain an airtight or leak-proof seal under standard conditions.

The results are interpreted based on the torque values measured during the test. Higher torque values typically indicate stronger seals, while lower values may suggest potential seal weaknesses. These results help determine whether the closure meets the required seal integrity standards for the product’s intended use.
