Lekkimisi

Lekkimisi is a term used in Estonian-language technical and everyday contexts to denote leakage or the act of leaking. The noun originates from lekima "to leak" and the abstract noun suffix -misi, yielding a concept that can refer to an instance of leakage or to the process itself.

In technical contexts lekkimisi describes unwanted escape of liquids or gases from a container, system, or enclosure. It is a central concern in plumbing, HVAC, chemical processing, energy, and automotive engineering, where controlling lekkimisi is essential for safety, efficiency, and environmental protection.

Assessment and management of lekkimisi involve leak detection and testing. Common methods include pressure-decay or pressure-rise tests, bubble tests, tracer-gas techniques, and helium leak testing. Results are reported as a leak rate or as a pass/fail against specified thresholds.

Terminology notes: lekkimisi can be used more generally to refer to leakage events outside technical contexts, such as moisture leakage in buildings or fluid losses in tanks. It is not widely standardized in international engineering vocabularies; English translations typically use "leakage" or "leak rate" depending on context.
