ESTECHMAGNETICS.COM | 785-806-5211 17 ESTECH MAGNETICS PRODUCTS 2025 Magnetic Force Testing on Mono4-FLEX X&Y Axis Yield Definition Magnetic force is tested to the yield condition of the bracket embodiment. For the purpose of the calibrated testing procedure, the yield point is defined as the average maximum tension force experienced which induces a deflection along the given axis of up to .25 inches parallel to the tested steel surface. Z Axis Yield Definition The yield point is defined as the maximum tension force experienced at the vertical (90 degree / Z axis) pull of breakpoint experienced tested perpendicular to horizontal steel surface. Reporting Results from these calibrated tension forces are aggregated into a spreadsheet with each procedure as the vertical column and the axis in the horizontal column. Please see below table for product testing of the Mono4-FLEX magnetic bracket. Video of all tests further record and confirm performance data. Please refer to Estech’s Standardized Magnetic Testing Procedure Testing Program and Specifications document for further information. Table 1: Working Load Table — 2X Safety Factor Recommended by ESTECH Estech recommends a safety factor or 2X when the consumer load is compared to calibrated factory tested ultimate load data. This table below will aid in determining the correct magnetic bracket size for needed capacity. An on-center spacing of no more than 5 feet is specified on this magnetic bracket system. Table 2: Working Load Table — Performance Data Testing by ESTECH This magnetic bracket has been factory tested in a calibrated condition. Many factors influence the magnetic performance in outdoor settings such as; steel type and thickness, temperature, moisture, thickness of coating systems, coefficient of friction of coating system and direction of force. Estech has used 1/4” mild steel with a 10-12 mil AWWA compliant coating system at 70° Fahrenheit average at all stated axis and variable angular directions of tensile pull force (lbf). Magnetic force improves with; thicker steel, ferrous metal, thinner coatings, rougher coatings, colder temperatures at dry conditions. Estech formulated this calibrated test standard to best model conditions commonly seen on water tower and similar outdoor settings. Note: these are ultimate loads. Highest forces at a maximum displacement of .25” were recorded and averaged. The results are located in the table below.
