Service life test

For testing products in long-term operation and a defined service life

Durability test stands: reliability and durability are the focus of the tests

Service life test stands are special test facilities used to check the service life and reliability of products. These test rigs enable manufacturers to simulate the actual service life of a product under realistic conditions and identify potential weak points or signs of wear at an early stage. Durability testing is an important step in the product development process as it ensures that a product will stand up to consumer demands and expectations. By carrying out long-term tests on durability test stands, manufacturers can improve the durability of their products, minimize potential failures and ultimately increase customer satisfaction.

The durability test includes various test scenarios such as continuous load tests, vibration tests, temperature cycling tests and many others. These tests are carried out under controlled conditions to ensure that the product meets the requirements in terms of performance, safety and durability. By using state-of-the-art durability test rigs, manufacturers can optimize their products and save costs at the same time. By identifying potential problems at an early stage, expensive product recalls can be avoided. In addition, durability testing enables continuous improvement of product quality and thus contributes to increasing a company's competitiveness.

The service life test is used to test a product in long-term operation and to qualify it for a defined service life. Customers who expect high reliability and availability of their measured values choose the ProfiMessage devices. An internal memory of 16 GB and autonomous control and regulation functions form the basis for PC-independent long-term recording and control. The devices work continuously, restart automatically in the event of a power failure and provide seamless documentation. The devices report a fault or failure by e-mail or switching output. The scheduler integrated in DataService also archives the data on a PC or server. Every user can access the current and historical data from the workstation with ProfiSignal evaluate.

Application highlights for durability test stands

  • Measurement, automation and analysis functions in one device
  • Several test benches can be operated independently of each other
  • Data security through automated reading of the data in the device memory
  • Data security and automatic restart in the event of a power failure
  • Monitoring of test specimens and e-mail/SMS message in the event of a fault

Practical example of a service life test

Autonomous service life testing of fan and cooling systems

An automotive supplier develops, tests and produces fan and cooling systems. Complex service life tests are carried out in order to guarantee the desired service life. The test specimens are installed in climatic chambers, where daily and annual cycles are simulated. The ProfiMessage devices work completely autonomously; only in the event of a fault is this reported by SMS. Over 70 climate chambers are operated in parallel. A continuous run of 2,000 or 3,000 hours is required. In addition to recording and monitoring, the setpoint profiles for the test specimens are also generated in the ProfiMessage device. The data is transferred online and automatically stored on a server. Despite the large volumes of data, ProfiSignal displays the entire test period at lightning speed. Outliers can be detected immediately.

Typical areas of application
the service life test

  • Environmental simulation of fan systems in motor vehicles
  • Endurance test stands for oven doors
  • Lifetime testing of window regulators
  • Cooktop and hotplate testing
  • Service life testing of fan motors
  • Measuring the long-term stability of solar modules
