videoXtens 2-120 HP

High precision for strain measurement of plastics and fiber-reinforced composites

The videoXtens 2-120 HP sets new standards in accuracy and reproducibility.

If high precision is required for strain measurement on plastics and fiber-reinforced composites, the videoXtens 2-120 HP is the perfect non-contact solution.

Compliance with the strict requirements for tensile modulus values to ISO 527-1 Annex C, including exact measurement of the tensile modulus values.
This high level of accuracy is also attained under temperature conditions inside a ZwickRoell temperature chamber.
As the system employs non-contact measurement, material characteristic values are unaffected. Operator influence is also minimized, ensuring consistent test results.

Typical applications videoXtens 2-120 HP

Plastics to ISO 527-1 or ASTM D638

Requirements of ISO 527-1 for determination of tensile modulus: max. error ± 1 µm / ±1.5 µm when measuring the differential displacement between two measuring points (with elongation of 0.05% and 0.25% of the initial gauge length, with an initial gauge length L₀ of 50 mm / 75 mm.
We recommend self-adhesive gauge marks (strips).

Specific advantages in this application

Satisfies the exacting calibration requirements for tensile modulus values to ISO 527-1, Annex C.
High-accuracy measurement of tensile modulus.
ZwickRoell extensometers exceed the requirements of the standards and are calibrated over the entire measurement range to Accuracy Class 0.5, ISO 9513.
Even brittle-fracturing plastics specimens can be tested without damaging the extensometer.
High-accuracy testing with ZwickRoell temperature chamber, including with determination of tensile modulus to ISO 527-1.
Enclosed system - connection via tunnel when testing in temperature chamber.
Resistant to environmental influences (e.g. air currents, variations in lighting); flexible tunnel minimizes signal interference.
Optimum, uniform specimen illumination by LEDs incorporated into the tunnel.

Fiber-reinforced composites

Tensile tests on filament strands and laminates of fiber composites, e.g to ISO 527-4/-5, ASTM D3039, ASTM D4018
In-plane shear tests (±45° method): In-plane shear response to ISO 14129 and ASTM D3518 (transverse strain software option required)

Specific advantages in the application:

Brittle-fracturing fiber composites can be tested up to break without damaging the extensometer.
Accuracy class 0.5 to EN ISO 9513. ZwickRoell extensometers exceed the requirements of the standards and are calibrated over the entire measurement range to ISO 9513, in accuracy class 0.5.
Accuracy class B1 to ASTM E83 from a gauge mark distance of 15 mm.
Highly accurate testing with ZwickRoell temperature chamber, also for determination of the tensile modulus to ISO 527-1.
The tunnel connection keeps the system closed for tests in a temperature chamber.
Resistant to environmental influences (e.g. air currents, variations in lighting): flexible tunnel minimizes signal interference.
Optimum, uniform specimen illumination by LEDs incorporated into the tunnel.
