The phrase "a test duration" is correct and usable in written English.
It can be used when referring to the length of time allocated for a test or examination.
Example: "The test duration is set for two hours, allowing students ample time to complete all questions."
Alternatives: "a testing period" or "a duration for the test".
This polishing is clearly observed on SEM images of the inner raceway after a test duration of only 0.5% of the calculated L10 life.
To test the performance of a tool designed to estimate functional capacity in order to select a bicycle ramp protocol yielding a test duration from 8 to 12 min in healthy individuals, and to assess differences in exercise responses between bicycle and treadmill tests.
After a test duration of 15 min, Ba is detected with a concentration of 3 µmol/L.
The final resilient concentration value of this experimental run is 547 µmol/L Ba after a test duration of 210 min.
Within 30 min the concentration of Ba increases to a value of 99 µmol/L and after a test duration of 90 min an almost stable concentration 180 µmol/L is reached.
Ad hoc-designed workflows were used for data curation and filtering, as well as for the extraction of LC50 data, which in this case is defined to be the concentration that causes death in 50%% of test Daphnia magna over a test duration of 48 h.
The LC30 is the concentration required to kill 30% of the members of a tested population after a specified test duration and is commonly used in mite pesticide exposure research [ 18].
The NSSM test avoids some of the drawbacks of the RCP test by using a lower applied potential and a longer test duration.
The incremental exercise test was performed using an individualized ramp protocol with a total test duration of 8 12 min (Working Group on Cardiac Rehabilitation & Excercise Physiology and Working Group on Heart Failure of the European Society of Cardiology 2001).
As also the ADHD group had a longer test duration it seems that time is a key problem for those children affected by ADHD-symptoms.
For specificity, we define a positive class as a domain of concentrations of Toxin A and Toxin B, which cause less than 50% population mortality after a specified test duration; all other combinations of concentrations by definition are assigned to the negative class.
