The forces have been determined at room temperature on a plate of polished steel (A36) with a thickness of 1/2 inch.  The pull force is applied perpendicular to the face of the plate.  A maximum deviation of -10% compared to the specified force is possible in exceptional cases, generally the value is exceeded.  Depending on the type of application (thickness/condition of base metal, temperatures, and direction of pull), the forces can be influenced enormously. Mounting on vertical surfaces can reduce the pulling force by up to 70%.The indicated values solely serve a basis for comparison under above stated conditions.
