The objective of tests on elastomers and foams is the straightforward and fast measurement of material elasticity. One material that is up to 100% elastic stores supplied energy and releases it at the moment the force is no longer applied. In contrast, material that is up to 100% plastic absorbs supplied energy completely. These characteristics are used to measure rebound resilience:
- Resolution 0.06 degrees.
- Extremely low-maintenance - fully automatic sequence with geared motor as sole actuator.
- Frictionless pendulum encoder.
- Wear-free mechanism - ideal for continuous operation.
- Dustproof keyboard.
- Stand-by mode and LCD display for low power consumption.
- Menu-guided operation.
- Pendulum height is easily adjustable via an eccentric with the help of a setting program.
- Included in the instrument are two test programs for determining oscillation time and friction.
- The required standard can be selected or the sequence configured.
- Multiple languages can be programmed (English, German plus one freely assignable language).
- Connection to a PC and to ZwickRoell's testXpert testing software is possible. ZwickRoell testing software offers comprehensive data transfer options (from instrument to PC) plus evaluation, processing, documentation and storing of test results.
- Integrated routine enables rapid error analysis.
The specimen plus interchangeable clamping fixture can be temperature-conditioned externally in a heated chamber.
The specimen clamping fixture is attached to the instrument base by means of a plug fastener, enabling rapid changes. This reduces temperature losses from the temperature-conditioned specimen during insertion into the tester.
A specimen holder with a temperature control unit for a temperature range of up to 100°C that can be electrically heated is available for tests at high temperatures.
A PC can be connected via the integrated RS232 C interface for output and processing of test results.
The ZwickRoell testing software provides options for evaluation, documentation, storage and data transfer. It can also apply and process measured values from various devices (e.g. pendulum impact testers, thickness measuring instruments, balances etc.).
