- Components to be tested: Parallel and circular displaced springs of all kind, with and without corrosion impact 
- Maximum load allowed for each of the two test positions : F_max = 40 kN 
- Number of springs to be tested simultaneously : limited by F_max 
- Stroke (displacement controlled) : S = 10 to 300 mm 
- Maximum length of springs : Lo = 600 mm 
- Testing frequency : fo = 0.44 x Root(nxR) [Hz] 
                      n = number of springs 
                      R = spring rate [N/mm] 
                      fo = 2 to 25 Hz 
- Mesurement of load and displacement (recording of spring rate; relaxation monitoring) 
Saltwater container (250 l) with individually programmable rain intervals and a heating system with temperatures up to 40^oC 
- Low noise level and vibration free (no foundation necessary) 
- Weight app. 2.4 to 
- Dimensions of the machine : app. L=1,800mm, W=2,000mm, H=2,500mm (additional floor space for control panel, corrosion generator, distilled water facility and hydraulic power station) 
- Air conditioner (60^oC, 95% humidity) 
 
Advantages Compared to Other Existing Spring Testing Machines:  

- Low energy consumption (app. 1 to 3 kW) 
- Easy to handle 
- Long life 
- Low maintenance costs 
- Broad use (also for tests under normal room conditions) 
- Spectrum testing possible 

Purpose of Testing:  
 
- Time- and cost-effective determination of fatigue resistance of springs with and without corrosion environment. 
- Simultaneous testing of a number of resilient elements by parallel and serial arrangement. The number of springs per test position is limited by the maximum load and the minimum frequency allowed (see technical specification). 
 
Typical Customers: 
 
- Manufacturers of all types of springs (research, development and quality control), e.g.: springs for railways, passenger cars, combustion engines, injection pumps, clutches, torsional dampers, two mass absorbers etc.
