3.0 L1 TEST METHODS- AN OVERVIEW Test templates are supplied standard on your L1 System and are designed to let you create a test in as few as two steps. Your L1 System features these) test templates for the most common types of force measurement testing: • Load Limit Test • Distance Limit Test LOAD LIMIT TEST The Load Limit setup lets you create a load limit test by specifying the limit value and the test speed. Your test will conclude when the load limit is achieved. This test is used when you are interested in determining the amount of deflection/extension the sample exhibits while being pulled or pushed to a load setpoint. 3.2 LOAD HOLD TEST • Break Limit Test • Cycle Limit Test 3.1 The Load Limit setup has an option that lets you specify a hold duration at the load limit. This can be used for creep and relaxation testing. The hold duration may be up to 99,999 seconds (27 hours). NOTE Long duration tests require a smaller sampling rate. The maximum number of data points that can be collected and saved is 100,000. Therefore, use a sampling rate of 1Hz for tests with a duration of 99,999 seconds. 3.3 DISTANCE LIMIT TEST The Distance Limit setup lets you create a distance limit test by specifying the limit value and the test speed. Your test will conclude when the distance limit is achieved. This test is used when you are interested in determining the amount of load the sample exhibits while being pulled or pushed to a distance setpoint. 3.4 DISTANCE HOLD TEST The Load Limit setup has an option that lets you specify a hold duration at the load limit. This can be used for creep and relaxation testing. The hold duration may be up to 99,999 seconds (27 hours). NOTE Long duration tests require a smaller sampling rate. The maximum number of data points that can be collected and saved is 100,000. Therefore, use a sampling rate of 1Hz for tests with a duration of 99,999 seconds. 3.5 BREAK/RUPTURE TEST The Break Limit setup lets you create a break test by specifying the break value and the test speed. Your test will conclude when the load drops by a percentage from a previously measured peak load. For example, if the user sets a Break % of 10%, the system will continuously measure the load value. When the load drops by 10% from a previously measured peak value, the data point associated with this drop in load is characterized as the "break point" for the sample under test. This test is generally used when you are interested in determining the maximum (peak) load and the distance at the maximum load.
3.6 CYCLE COUNT TEST The Cycle Count test lets you create a test where the crosshead moves continuously between two setpoint at a specified speed. You will specify the two setpoints and the crosshead velocity. You will also specify the number of cycles or counts to be performed. The test may have a maximum of 99,999 counts or cycles. 3.7 CYCLE DURATION TEST The Cycle Duration test lets you create a test where the crosshead moves continuously between two setpoints at a specified speed. You will specify the two setpoints and the crosshead velocity. You will also specify the duration of the test, i.e., how long the crosshead will cycle for until the test is completed. The test may have a maximum duration of 99,999 seconds (27 hours). NOTE Long duration tests require a smaller sampling rate. The maximum number of data points that can be collected and saved is 100,000. Therefore, use a sampling rate of 1Hz for tests with a duration of 99,999 seconds.
