We use high technology to increase safety and reduce running costs.

LIMAtest determines the residual wall thickness in the vulnerable areas and evaluates the entire mast system using statics. It is suitable as a non-destructive test method according to DIN 1090-2. We assume liability for measurement errors. Our method has also been accredited.

Your 6 advantages:

1. We drive innovation: Together with the biggest and most respectable technology partners, we have been driving the development of innovative testing technology for almost 20 years. We are especially proud of our long-lasting and productive cooperation with the Fraunhofer Institute for Nondestruvtive Testing IZFP.

2. Test set-up: ZWP is one of only a few companies on the market to carry out stability tests on lighting masts using a mobile measuring device. This patented process was developed in cooperation with the Fraunhofer IZFP and is both accredited and certified.

3. No mechanical force transmission: We don't transmit any forces into the mast. As a result, we are able to guarantee that the mast will remain undamaged during testing.

4. Test execution:  According to DIN EN 1090-2, ZWP's ultrasonic method conforms to the criteria of a stability test; the positional stability can be evaluated optionally.

5. Documentation of testing results: You will receive an Excel table that provides details on the individual masts. For each mast you will receive an individual data sheet: Mast statics, at least 2 digital photos with information on the mast geometry, the wind load as calculated on site, GPS measurements

6. Follow-up recommendation for stable masts: Unlike methods that issue recommendations of up to 5 years only, we certify between 5 and 12 years. And all the results are clearly documented.
