driftssikkert

Driftssikkert is a Norwegian term used in engineering and technology to describe systems, components, or processes that remain functional and safe despite drift or variation in conditions, measurements, or environment. The concept overlaps with fault tolerance, robustness and fail-safety, emphasizing continued operation and safety rather than perfect accuracy.

Etymology: drift means operation or running, sikker means safe. Combined, driftssikkert conveys that a system stays safe during drift. In Norwegian technical usage both driftssikker and driftssikkert appear, with slight emphasis differences depending on context or standard.

Contexts and design: driftssikkert is used in industrial automation, process control, instrumentation, and software reliability. Key design principles include redundancy, fail-safe or degraded-mode operation, calibration drift compensation, environmental robustness, self-checking health monitoring, and error handling that preserves safe operation.

In English contexts the closest equivalents are fault-tolerant, robust, drift-resistant or drift-stable, depending on emphasis. The term is often found in specifications, safety assessments, and reliability discussions. See also fault tolerance, reliability engineering, redundancy, and safety-critical design.
