Maximum allowed loads

For most of our products maximum allowed loads are described in the article tables. Stated values are determined by:

• Walraven developed measuring method
• the measuring method described in the testing prescriptions RAL-GZ 655, which is set up by the ‘Gütegemeinschaft Rohrbefestigung’. If the product is provided with the ‘RAL-Gütezeichen’, the test results are checked by an independent testing institute.

For plastic clamps, breaking loads are also described in the article tables.

Deviations compared with printed catalogue

Our web catalogue is updated each day and contains where possible the most current details. As more and more Walraven products are tested according to new international measuring methods and quality standards, the maximum allowed load can differ from printed catalogues.
