Falingscriteria

Falingscriteria is a concept used in reliability engineering and quality assurance to define the conditions under which a system, component, or process is considered to have failed or no longer acceptable for operation. It consists of a structured set of rules, thresholds, and decision logic that translate raw measurements and observations into a pass/fail verdict. The term is a general rather than a standardized label; it may be found in different languages as "failure criteria" or close equivalents, and in Scandinavian technical literature it may appear as a local spelling variation.

Components typically include measurement limits, time-based allowances, data quality requirements, and escalation actions. Thresholds may be fixed or adaptive, with safety margins that account for measurement noise and environmental conditions. Decision logic often employs simple comparisons, logic circuits, or statistical methods to determine when the criteria are met.

Applications span reliability engineering, preventive maintenance, process control, and software quality assurance. They help define maintenance triggers, alarms, and shutdown logic in a way that is auditable and repeatable.

Example: In a production line, falingscriteria might specify that if product output falls below a target by more than 5 percent for three consecutive inspections, or a critical sensor shows a reading outside the safe range for more than 60 seconds, a fault is declared and a maintenance or shutdown action is initiated.

Related concepts include failure criteria, fault detection, alarm management, and risk-based maintenance. Because the term is not universally standardized, practitioners usually define falingscriteria within their quality management or reliability framework and document it in procedures and specifications.
