21 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Soft foot
- An unsuitable support condition in which a machine foot does not seat appropriately, potentially distorting the assembly when its fasteners are tightened.
- Measurement resolution
- The smallest distinguishable displayed or detected increment of an instrument, distinct from its accuracy and the uncertainty of the complete method.
- Tolerance interval
- The permitted range specified for a feature, which must be distinguished from its nominal value and assessed with a suitable measurement method.
- Flexible coupling
- A torque-transmitting connection with specified accommodation for limited relative movement, which does not eliminate appropriate support and alignment requirements.
- Bearing installation load path
- The path by which mounting force reaches the specified interference-fitted ring without imposing damaging assembly load through the rolling elements.
- Nominal dimension
- The reference feature size stated on a drawing, which does not by itself describe the permitted tolerance or prove actual part conformance.
- Observed symptom
- A documented change in performance or condition that can motivate investigation but does not alone establish the unique failed component or root cause.
- Condition-based task
- A maintenance action triggered by relevant observed equipment condition under appropriate assessment criteria, rather than simply by elapsed calendar time.
- Root-cause hypothesis
- A proposed explanation for the failure mechanism that must be tested against suitable evidence, not established merely by replacing a named part.
- Controlled restoration
- An authorized return-to-service process including the relevant protective functions, functional checks, records and handover under actual equipment and site requirements.
- Mean repair duration
- A defined average of relevant active repair time divided by the counted repairs, which must not be confused with every elapsed outage or logistical delay.
- Maintenance history
- A controlled record of asset conditions, faults, actions and evidence supporting comparisons and investigation rather than merely storing the latest replacement invoice.
- Effective cylinder area
- The relevant pressure-loaded area for the stated direction, with the rod area subtracted on the annular side of a double-acting cylinder.
- Meter-out control
- Flow restriction on an actuator’s exhaust path in a specified circuit, which is not by itself a universal safe holding device for an overrunning load.
- Pressure versus flow
- Pressure describes force intensity while flow describes volume rate; confusing them can give an incorrect explanation for actuator force or speed.
- Cavitation
- Formation and collapse of vapor cavities when local liquid pressure becomes unsuitable, distinct from simply drawing free air into a system.
- Load-control arrangement
- An engineered combination managing the specified load and failure conditions, which cannot be replaced by assuming any simple throttle safely holds a suspended mass.
- Live-zero signal
- A measurement range whose normal zero-value output is above zero electrical signal, allowing some abnormal observations to be distinguished without uniquely diagnosing their cause.
- Feedback error
- The signed difference between the stated reference and measured value, whose interpretation requires the actual loop convention and operating context.
- Sensor range
- The specified interval over which a sensor is intended to measure, distinct from its resolution, accuracy and allowed operating environment.
- PLC input state
- The value presented to the controller by its configured input channel, which may differ from a local process-gauge observation and requires appropriate diagnosis.
