The Clamp Mouth Distance in the NG-HE Elmendorf machine is an important technical specification that refers to the distance between the clamps that hold the material being tested during the tear test. Specifically, it is the distance between the two clamping jaws that hold the sample in place before the pendulum is released to initiate the tear.

In the NG-HE Elmendorf machine, the Clamp Mouth Distance is specified as 2.8mm ± 0.3mm, meaning that the distance between the clamping jaws should be between 2.5mm to 3.1mm. This ensures that the sample is held firmly and consistently during the tear test, which is essential for obtaining accurate and reliable results.

The Clamp Mouth Distance is an important parameter to consider when selecting a tear testing machine, as it can affect the tearing force measurement. A wider or narrower distance between the clamping jaws may result in a lower or higher tearing force measurement, respectively, due to changes in the clamping force applied to the sample.
