Tettinspeksjon

Tettinspeksjon is a systematic inspection and testing process aimed at verifying the tightness of a system, component, or barrier to prevent leakage of gas, liquid, or air. The term is used in contexts such as construction, plumbing, HVAC, and industrial piping, where the integrity of joints, seals, and enclosures is critical for safety, energy efficiency, and reliability. The goal is to identify any leaks or insufficient sealing that could lead to safety hazards, material damage, or energy losses.

The process typically combines planning with a combination of inspection methods. Visual inspection assesses visible joints and seals, while functional tests may involve applying pressure or vacuum, monitoring for pressure decay or rise, and using leak-detection equipment. Tracer gas methods (for example using a traceable inert gas) and detectors, dye tests, infrared thermography, or acoustic emission techniques may also be employed. Tests are conducted under prescribed conditions, with defined acceptance criteria, and results are documented to support compliance and certification. If leaks are detected, corrective work is performed and the system retested.

Tettinspeksjon is guided by applicable national regulations and industry standards for safety and performance. In practice, qualified professionals and approved contractors perform the inspections, ensuring that testing procedures protect workers and the public. The outcome informs commissioning, maintenance planning, and regulatory compliance, contributing to safety, energy efficiency, and long-term system integrity. Limitations may include access constraints, system shutdown needs, and test conditions that do not perfectly replicate normal operation.
