20 cards. Read the term and the definition here. The deck at the top of this page is optional.
- System boundary
- The defined part of an installation being analyzed, which helps identify relevant inputs, outputs, interfaces and assumptions before diagnosing a fault.
- Fault symptom
- An observed departure from intended operation, distinguished from assuming that a particular component has already been proven to cause the problem.
- Diagnostic evidence
- Information from observations or appropriate tests that supports fault analysis when interpreted under the actual operating conditions and documentation.
- Technical manual
- The equipment-specific reference describing relevant characteristics, procedures and limits, whose version and applicability should be checked before use.
- Tolerance
- The permitted variation for a specified characteristic under defined conditions, distinguished from an unrestricted allowance for any inaccurate result.
- Calibration
- A documented comparison relating instrument indications to reference values under specified conditions, rather than automatically repairing every instrument defect.
- Measurement uncertainty
- The quantified dispersion associated with a measurement result, which must be distinguished from an unnoticed mistake or an assumed exact value.
- Series connection
- An arrangement connecting components along one path, whose voltage, current and resistance behavior depends on the actual circuit model.
- Parallel connection
- An arrangement connecting components across common nodes, requiring analysis of branch currents and equivalent behavior under the stated conditions.
- Power factor
- The ratio of real power to apparent power in an AC system, interpreted with the applicable waveform and operating assumptions.
- Vector resultant
- The combined vector obtained by accounting for the magnitudes and directions of contributing quantities, rather than adding magnitudes in every situation.
- Unit conversion
- A change between equivalent measurement units using the correct scale relationship while preserving the physical quantity and dimensional consistency.
- Stored energy
- Energy remaining in a system that may present a hazard after a normal stop, requiring the appropriate authorized control and verification.
- Isolation
- Separation from relevant energy or other sources through the actual authorized procedure, distinguished from merely assuming a stop control removes all hazards.
- Return to service
- The authorized restoration of equipment to use after required work and checks, supported by evidence rather than an incomplete inspection signature.
- Tool accountability
- The controlled tracking of tools and other items to prevent loss, unauthorized access and foreign-object hazards during maintenance work.
- Fault tree
- A structured representation connecting a defined failure event with possible contributing causes, whose branches require evidence rather than automatic acceptance.
- Preventive maintenance
- Planned work intended to reduce failure risk according to the applicable equipment requirements, distinguished from every possible diagnostic or corrective activity.
- Configuration control
- The management of an item approved arrangement, versions and changes so that documentation and actual equipment remain consistent.
- Technical handover
- Communication of equipment condition, completed work, outstanding hazards and relevant records to the next responsible person or team.
