4.3.3.3 % DROP The % Drop is the percentage drop in load from the measured maximum (peak) load value. If the % Drop =5%, the break occurs when the measured load is a 5% drop from the measured maximum load after the Minimum Break value. If the Break % = 25%, the break occurs when the measured load is a 25% drop from the measured maximum load after the Minimum Break value. EXAMPLE • If the Minimum Break = 10 lbf • If the % Drop =25% The L1 software will monitor the measured load when the test starts. Once the measured load equals and exceeds the 10 lbf Minimum Break target, the L1 software will begin to monitor the load while looking for a reduction in load by 25%. If the maximum measured load is 100 lbf and when the load drops to 75 lbf, the test will finish. The maximum load is 100 lbf and the distance result is the distance the crosshead moved to get to the 100 lbf maximum. 4.3.3.4 TEST SPEED The Speed value is your test speed. This is the velocity you want your crosshead to travel at from when you start your test to your Target Load setpoint. Speed units may be either in/min (inch per minute) or mm/min (millimeter per minute). You may specify the units of measure for speed using the Pre Test options. Your L1 System has a speed range from 0.001 to 40.0 inch per minute (0.02 to 1016 mm per minute).
4.3.3.5 EXCEPTIONS The optional exception rules for the Break Limit test are: • Load • Distance LOAD EXCEPTION Enter a Load value. If the measured load equals this value, and the distance limit has not been achieved, the test will stop. DISTANCE EXCEPTION Enter a Distance value. If the measured distance equals this value, and the load limit has not been achieved, the test will stop.
