An R&D lab is frequently testing textiles that typically break around 900 N. While this falls within the capacity of a 1 kN load cell, it is best to use a 2 kN cell for several reasons: a higher-capacity cell leaves room for future development of stronger materials and reduces the risk of overloading the 1 kN cell and damaging it. A general rule of thumb is to select a load cell where the peak load experienced during testing falls under approximately 80-90% of the load cell’s maximum capacity
