The test piece was stabilized under the test conditions and the test was restarted from the interruption point.
2. The test was interrupted. In the event of an unexpected test interruption, resulting in a test condition above the specified value and exceeding the tolerance, the test conditions shall be stabilized within the tolerance and maintained at this level until a comprehensive visual inspection and technical evaluation can be performed to determine the test. Interruption affects the test results. If the visual inspection or technical evaluation concludes that the test interruption does not adversely affect the final test results, or that the effect of the interruption is negligible, the test conditions before the interruption shall be re-stabilized and the test shall continue from the point in time when the tolerance is exceeded. .
