II.6 Test ResultsII.6.1Test PassedWhen a yield test runs successfully, the resultant Yield Stress (Pa), the % Torque value at thetime of the yield and the Temperature at yield are printed.Test (#5: Sample Tst) CompleteYield Stress (Pa) = 726.36 % Torque @ Yield = 73.56 Temperature = 25.5CIn addition, the results are shown on the display as follows:II.6.2 Test Failed%=73.56 025.5CYIELD=726.36 PaFigure 21Some of the reasons a yield test may fail are as follows.II.6.2.1 Under-Range ConditionOnly yield measurements in the % Torque range from 10% to 100% will be accepted. Ifa Yield Stress is reached before the % Torque value is 10%, an Under-Range error causes thetest to end.The following is sent to an attached printer:Test (#5: Sample Tst) CompleteTest Failed = Under-rangeThe following screen is displayed:YIELD ERRORUNDER-RANGEFigure 22II.6.2.2 Over-Range ConditionOnly yield measurements in the % Torque range from 10% to 100% will be accepted. IfYield Stress is not reached before the measured % Torque value reaches 100%, an Over-Range error causes the test to end.The following is sent to an attached printer:Test (#5: Sample Tst) CompleteTest Failed = Over-rangeThe following screen is displayed:YIELD ERROROVER-RANGEFigure 23Brookfield Engineering Labs., Inc.

II.6.2.3 User-Defined Limit ConditionWhen an upper and lower limit has been imposed upon the Yield Stress by the user, anyresulting Yield Stress that falls outside these limits causes the test to fail with a LimitViolation Condition. One of the following messages is sent to the attached printer dependentupon which limit was violated:Low Limit ViolationTest (#5: Sample Tst) CompleteYield Stress (Pa) = 196.53 % Torque @ Yield = 27.4 Temperature = 250.5CTest Failed = Yield Stress Below Low LimitHigh Limit ViolationTest (#5: Sample Tst) CompleteYield Stress (Pa) = 996.53 % Torque @ Yield = 78.6 Temperature = 250.5CTest Failed = Yield Stress Above High LimitThe following screen, showing first the violated limit value followed by the resultingYield Stress, is displayed:II.6.2.4 Test Cancelled By UserLIMITS EXCEEDEDYLD:800 (996.53)Figure 24When a test is cancelled by the user, either by pressing the ESC key during a running testor by canceling the test via the EZ-Yield software (See Section II.4.6), the following issent to the attached printer:Test (#test number: test name) CancelledTest Failed = Cancelled By UserThe following screen is displayed:TEST TERMINATEDBY USERFigure 25Brookfield Engineering Labs., Inc.
