Special tests

Written by on .

Definition: Special tests are individually developed or adapted testing methods for clarifying specific technical questions that are not sufficiently covered by standardised normative tests. They frequently combine several analysis and testing methods. The aim is a robust, problem-oriented assessment.

Practical relevance: Fields of application include complex failure cases, novel materials, atypical loading scenarios or special regulatory requirements. Special tests can comprise modified mechanical tests, combined environmental stresses or special specimen geometries. A traceable documentation of the test set-up, boundary conditions and measurement uncertainty is essential.

Decision-making perspectives:

  • Technical decision-makers: Clarification of specific failure mechanisms or suitability verifications beyond standardised tests.
  • Purchasing/project management: Definition of individual acceptance criteria for innovative products.
  • Science: Development of validatable test designs and comparison with reference methods.
  • Insurance/law: Court-proof documentation in exceptional failure or dispute cases.

Typical testing or verification methods: Combined climatic and load tests, modified fatigue tests, special corrosion or media tests.

FAQ:

  • When are special tests required?
  • When normative standard tests do not sufficiently represent the specific technical question.
