In Germany, tests and approvals according to Im 1 – Im 4 are processed in accordance with the rules of the ZTV-W and the related „Richtlinien zur Prüfung von Beschichtungsssystemen für den Korossionsschutz im Wasserbau (RPB - Guidelines for testing coating systems for corrosion protection in hydraulic engineering)“. Aside from lab testing, our systems are also tested in long-term exposure. If the results of the tests are positive, they will be included in the quality-assessing lists of the BAW (Bundesanstalt für Wasserbau [German Federal Waterways Engineering and Research Institute]). The Federal Waterways Engineering and Research Institute in Karlsruhe is responsible for this.
Further information on the Federal Waterways Engineering and Research Institute can be found at www.baw.de.
The quality-assessing lists are available under the category - Service & Knowledge - Publications - Quality Assessment.
The ZTV-W, “Additional Technical Terms and Conditions – Hydraulic Engineering” for corrosion protection in hydraulic steel structures are valid for all firm and movable parts of hydraulic engineering, as well as metallic pieces of equipment of waterworks, both in construction and maintenance during the plant and construction stage. Correspondingly, they can also be used for corrosion protection in ships, swimming devices, navigation, steel sheet piles in hydraulic structures and offshore plants.
However, additional tests going beyond requirements of ZTV-W are used according to standards and prerequisites of energy suppliers. Thus, our special “Delta-T Tests” are done to simulate and test our protective paint systems when it comes to high temperature variations. If positive, our protective paint systems can also be used, for example, to protect the insides of cooling water pipes from corrosion.
Further information can also be found in our hydraulic steel construction brochure.
