Ice water shock test
Reliable testing methods for the most demanding requirements
What is an ice water shock test?
The ice water shock test is one of the most important methods for realistically simulating the service life and tightness of products. It proves that components function reliably even during abrupt temperature changes and are protected against water ingress—a decisive criterion for quality assurance in industries such as the automotive, electronics, and defence industries.
Test procedure: How the ice water shock test works
During the test, the test specimen is heated to up to +200 °C in an oven using convection. This is followed by a rapid drop in temperature by immersing it in a cold test medium, e.g., salt water, with a temperature of +2 to +4 °C. This extreme stress simulates shock-like cooling, as can occur in practice, for example, due to wet spray or sudden immersion.
Our test systems are designed to ensure that:
- the immersion bath is reliably cooled by a saltwater-resistant heat exchanger,
- the re-cooling device is individually adjusted to the heat input of the test specimen per immersion process,
- gentle circulation of the water prevents temperature stratification,
- cycle times are freely programmable (e.g., duration of the heating or immersion process),
- and the immersion depth can be precisely controlled via the program control.
Continuous recording of all relevant parameters ensures precise, reproducible, and standard-compliant documentation of the test results.

Our ice water shock test chambers can be equipped with numerous options to make testing processes safe, reproducible, and efficient:
- Extraction of explosive gases: Ensures the safe removal of potentially hazardous vapors and contributes to operational safety.
- Pressure relief valves: Protect the system in the event of sudden pressure increases through controlled relief.
- Gas warning sensors: Detect escaping gases or vapors at an early stage – for increased safety in the test room.
- Programmable digital channels: Enable flexible control and automation of complex test sequences.
- Test specimen sensor: Records the exact surface temperature of the test specimen for precise process monitoring and documentation.
- Heavy-duty design: Robust construction for large or heavy test specimens – ideal for applications in the automotive or mechanical engineering industries.
