Kontrolltesztek

Kontrolltesztek are tests performed to verify that a product, system, or process remains within defined limits and satisfies specified requirements. They are a core element of quality control and are commonly used alongside verification and validation activities to confirm performance, safety, and regulatory compliance.

The scope of kontrolltesztek varies by field. In manufacturing and construction, they often involve measurements against specifications, calibration of instruments, functional checks of components, and safety-related tests. In software and information technology, they refer to checks that ensure changes do not break existing functionality and that the system behaves under expected conditions. Across domains, kontrolltesztek are designed to detect deviations early and prevent faulty outputs from reaching customers or end users.

Kontrolltesztek are planned, repeatable, and traceable. They rely on clearly defined acceptance criteria and standardized measurement methods. Test results are documented to demonstrate conformity with requirements and to support accountability and audits.

The process typically includes defining requirements and criteria, designing test cases, selecting appropriate test conditions and samples, executing the tests, and comparing results with the acceptance criteria. When deviations are found, corrective actions are implemented and, if needed, retesting is performed to verify that the issues have been resolved. Documentation of procedures, equipment calibration, and test reports ensures traceability and regulatory compliance.

Relation to other QA concepts: kontrolltesztek complement broader quality assurance activities and may be distinguished from broader qualification or validation efforts. They help ensure ongoing reliability, safety, and performance of products, systems, and processes throughout their life cycle.
