Selecting drainage products: Take load classes into account!
Covers for drainage products intended for installation in floors and ground, such as drains, separators and pumping stations, must be able to withstand the maximum possible loads at the respective installation site. The test load used to test a cover is indicated by its load class. This must be taken into account when selecting a product; in case of doubt, the next higher load class should be chosen. The choice of the appropriate class is the responsibility of the designer.
