Break Strength Testing
National Technical Systems (NTS)
To determine the failure point or break strength, you will need to define what a break is (break detector). Generally, there are two common types of breaks: the sharp break is referred to the measurement when load or force drops by 5% from its peak load measurement. A percentage break is another form of break and is generally determined by the sample material and its relationship to load degradation from a peak load measurement. A plastic material will likely have a load drop of 5%, but not represent a break. In this case, a percentage break would need to be applied. In a tensile test, the breaking load is the break strength.
