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. Sensors, instruments, and actuators are integrated into a functional test rig for data acquisition. The function test is used to test the operating functionality of components and simulate whether a part fulfils the predefined features.
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 cycle test stand with vacuum test
Pressure cycle test cooling systems of ECUs, PTC heaters, high-voltage coolant heaters, ACDC and DCDC converters and other media-carrying components while controlling the ambient and media temperature of e.g. water-glycol at temperatures from -40 °C to 140 °C .
Function test bench: Battery simulation under the influence of temperature
A temperature-controlled volume flow (e.g. 50 l/min) can be generated with the Poppe + Potthoff test stands for functional testing of media-carrying components. In addition, a component from e-mobility can be energized if required and pressure cycles applied.
Leak Test Stands
With the leak test rigs from Poppe + Potthoff, various components and assemblies can be tested for leaks by means of a drop in pressure. Depending on the test requirements, our systems including a vacuum unit and low-pressure or high-pressure module can be designed for optimal leak testing. In addition, Poppe + Potthoff offers e.g. bubble tests in a water bath / underwater tests with air and gas.
Burst Test Stands up tp 200 bar
In order to prove the quality of media-carrying components, hose lines, pipes, pressure vessels and other components are pressurized until they burst.
Autofrettage up to 12 0000 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 Boosters
Poppe + Potthoff Maschinenbau GmbH supplies compressor units and pressure control systems up to 400 bar. We offer you ready-to-connect units to increase the existing pressure for pneumatic and hydraulic applications. This allows the performance of existing systems to be expanded flexibly and efficiently.
Test bench for H2 components
We offer pressure test systems for the development and validation of hydrogen and nitrogen components. The focus is on test benches in the area of pressure cycle testing, bursting 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 optionally integrated climatic chamber and a gas sniffer (e.g. Inficon) to detect leaks in H2 components such as on-tank valves, hoses, pipes, fittings, regulators, valves and fuel cell components.
Automotive
Automotive testing includes a wide range of tests. Poppe + Potthoff Maschinenbau supports the industry with state-of-the-art pressure test benches, autofrettage systems and function test benches.
Aerospace
Test systems by Poppe + Potthoff Maschinenbau put fluid systems and components for aviation applications to a hard test. During a longterm design and service life test, they undergo up to millions of pressure load changes in order to simulate the service life of a component.
Home Appliances
Household appliance manufacturers are aware of the importance that their media-carrying components must be leakproof from day one, and components must be able to withstand a higher pressure load than the operating pressure. Poppe + Potthoff Maschinenbau supports the industry with various pressure testing systems.
Medizintechnik
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 verification processes ensure the quality of a component during research and development, and production.
Shipbuilding
Marine engines are made up of components that are exposed to extremly high pressures and require pressure testing. Among many others, cooling systems, pumps and valves in ship engines are subjected to pressure and tested for their resilience using pressure test benches from Poppe + Potthoff.
Oil and Gas
Various components from the oil and gas industry can be tested on Poppe + Potthoff pressure test benches. Drill pipes, pipes and (gas) valves are components that are exposed to changing pressure and temperature conditions and require pressure testing to ensure quality and safety.
