Retesting Procedure
Retesting defines when and under what conditions failed tests may be repeated. It prevents manipulation of the test piece.
Physical-Chemical Mechanism of Action
The test repetition is a set of rules that specifies the conditions under which a failed test can be repeated. It aims to ensure that the test piece is not tampered with and that the integrity of the testing process is maintained.
Metallurgical Relevance & Welding Risks
Uncontrolled or faulty repetition of tests can lead to manipulations where the test piece is altered. This can give false results and compromise the safety of the component. Additionally, an inappropriate number of repetitions can damage the material or impair its properties.
Workshop Practice & Instructions
Failed tests may only be repeated under strictly controlled conditions. This includes using a new test piece and adhering to all relevant standards and protocols. It is important that each repetition is documented and reviewed by an independent examiner.
