Calibration and Maintenance Control

This domain covers the governance systems that maintain validated state across facilities, utilities, equipment, instruments, and computerized systems. It addresses calibration strategy, metrology traceability, preventive maintenance, impact assessment, and integration with change control and periodic review to ensure sustained compliance and operational control.

  • Periodic Review and Continued Verification

    Calibration and preventive maintenance programs require ongoing evaluation to confirm continued effectiveness, stability, and regulatory suitability. Periodic review provides structured oversight of measurement performance and equipment reliability beyond routine task execution. Purpose and Scope Calibration and maintenance activities are event-driven controls. Periodic review is a time-based surveillance mechanism designed to evaluate overall program performance and…

  • Change Impact on Calibration and Maintenance

    Modifications affecting instrumentation, measurement systems, maintenance strategies, or reliability controls must be evaluated to ensure continued suitability, traceability, and validated state. Change management within this domain is not a general facility activity. It specifically addresses how changes influence measurement accuracy, maintenance effectiveness, and lifecycle control integrity. Purpose and Scope Calibration and preventive maintenance programs are…

  • Preventive Maintenance and System Reliability Strategy

    Preventive maintenance is a structured control program designed to preserve equipment reliability, maintain validated state, and prevent unplanned failures that may affect product quality or GMP system performance. Purpose and Scope In GMP-regulated environments, equipment and utility systems must operate consistently within validated parameters. Mechanical wear, component degradation, environmental exposure, and operational stress introduce performance…

  • Calibration Program and Metrology Control

    A compliant calibration program ensures that instruments used to control or monitor regulated processes consistently perform within approved limits and support defensible qualification data. Purpose and Scope In GMP-regulated environments, measurement accuracy directly affects product quality decisions and the credibility of qualification and monitoring data. Parameters such as temperature, pressure, flow, humidity, differential pressure, conductivity,…
