A function test bench is a system that tests a component under real operating conditions according to predefined parameters. Sensors and instruments are integrated for data collection. The functional test is used to test and simulate the operability of components.
Function Test Rig
media & ambient temperature control
A function test rig is a complete system that controls, measures, and evaluates a DUT (device under test) according to pre-defined parameters. Hence, sensors, instruments, and actuators are integrated into a functional test rig for data acquisition. Typically a function test is used to test the operating functionality of components and simulate whether a part fulfils the predefined features. Poppe + Potthoff Maschinenbau function test rigs enable reliable, repeatable and accurate testing. Consequentially, we tailor our rigs to your requirements and work together to find an ideal solution for your components and test setups.
For example, we offer a functional test rig for testing the power consumption of a battery while attached to the cooling circuit enabling data acquisition under real-life conditions. While applying sinusoidal pressure curves the test rig gathers data for the component designer to optimize the part.
Function test of energy efficiency of the battery during operation
In many EVs, the heating and cooling systems drain the battery and negatively affect the vehicle’s range. Comparing test results before and after a load change test on a function test bench can show how power consumption and performance change over the vehicle’s service life. The test object is connected to the power supply (low voltage 0-20VDC/5A) or high voltage (0-600VDC/150A) and the test media circuit. The test medium is circulated at a temperature of between -35°C to +100°C (-31°F to +212°F) and a flow rate of 1-50 l/min. The test can also be carried out in a climatic chamber at -40°C to +140°C (-40°F to +284°F) simulating changing ambient temperatures such as simulating ice-cold temperatures in Canada during Winter as well as dry heat around the Sahara desert.

PRESSURE TEST BENCHES AND APPLICATIONS
PRECISE, REPEATABLE AND RELIABLE
As a specialist in pressure testing technology and state-of-the-art test rigs, Poppe + Potthoff Maschinenbau supports the development and production of particularly resilient components made of various materials – especially for automotive, shipbuilding and mechanical engineering as well as fluid and the medical industry. We offer individually designed test benches such as burst pressure test rigs, pressure cycle test benches, leak test systems, functional test rigs and autofrettage systems.
Pressure change test stand with vacuum testing
Subject cooling systems of ECUs, PTC heaters, high-voltage coolant auxiliary heaters, ACDC and DCDC converters, and other media-carrying components to pressure tests while controlling the ambient and media temperature of, for example, water-glycol at temperatures from -40 °C to 140 °C.
Function test stand: battery simulation under the influence of temperature
For functional testing of media-carrying components, a temperature-controlled volume flow (e.g. 30l/min) can be generated with the Poppe + Potthoff test benches. In addition, a component from e-mobility can be energized if required.
Leakage test stand
Poppe + Potthoff leak test stands can be used to test various components and assemblies for leaks by means of a pressure drop. Depending on the test requirement, our systems can be designed including vacuum unit and low pressure or high pressure module for optimal leak testing. In addition, Poppe + Potthoff offers e.g. bubble tests in a water bath / underwater tests with air and gas.
Bursting pressure test rig < 200 bar
To prove the quality of media-carrying components, hose lines, pipes, pressure vessels and other components are pressurized until they burst.
Bursting pressure test rig < 200 bar
A flexible and expandable system for performing autofrettage on various components such as common rails and pump heads up to 12,000 bar.
Compressed air booster
Poppe + Potthoff Maschinenbau GmbH supplies compressor units and pressure control systems up to 400 bar. We offer ready-to-connect units to increase the existing pressure for pneumatic and hydraulic applications. This allows the performance of already existing plants to be expanded flexibly and efficiently.
Test bench for H2 components
We offer pressure testing equipment for the development and validation of hydrogen and nitrogen components. The focus is on test benches in the area of pressure cycling, burst pressure testing, and hydrostatic strength testing.
1050 Bar Helium / Nitrogen / Hydrogen
A leak test bench equipped with a pressure module up to 1050 bar, an optional integrated climate chamber and a gas sniffer (e.g. Inficon) to detect leakage on H2 components such as ontank valves, hoses, pipes, fittings, regulators, valves and fuel cell components.
Automotive
Automotive testing involves a wide range of tests. Poppe + Potthoff Maschinenbau supports the industry with state-of-the-art pressure test benches, autofrettage systems and functional test benches.
Aerospace
Test systems from Poppe + Potthoff Maschinenbau put fluid systems and components for aerospace applications to a tough test. In the service life test, they undergo millions of pressure load cycles to simulate the service life of a component.
Home Appliances
Household appliance manufacturers are aware of the importance of ensuring that their media-carrying components are leak-proof from day one and that components can withstand a pressure load higher than the operating pressure. Poppe + Potthoff Maschinenbau supports the industry with various pressure testing systems.
Medical Technology
Test benches for medical technology components from Poppe + Potthoff Maschinenbau put a wide variety of components to the test. Reliable, repeatable and accurate pressure tests and test processes ensure the quality of a component during research and development.
Shipbuilding
Marine engines are composed of components that are exposed to high pressures and require pressure testing of any kind. Cooling systems, pumps and valves of marine engines are exposed to pressure and are tested for their load capacity with pressure test benches from Poppe + Potthoff.
Oil and gas
Various components from the oil and gas industry can be tested on pressure test benches from Poppe + Potthoff. Drill pipes, tubes and (gas) valves are components that are exposed to changing pressure and temperature conditions and require pressure testing to ensure quality and safety.
