TPFP Technicien Maintenance Industrielle key terms

An unsuitable support condition in which a machine foot does not seat appropriately, potentially distorting the assembly when its fasteners are tightened.

The smallest distinguishable displayed or detected increment of an instrument, distinct from its accuracy and the uncertainty of the complete method.

The permitted range specified for a feature, which must be distinguished from its nominal value and assessed with a suitable measurement method.

A torque-transmitting connection with specified accommodation for limited relative movement, which does not eliminate appropriate support and alignment requirements.

The path by which mounting force reaches the specified interference-fitted ring without imposing damaging assembly load through the rolling elements.

The reference feature size stated on a drawing, which does not by itself describe the permitted tolerance or prove actual part conformance.

A documented change in performance or condition that can motivate investigation but does not alone establish the unique failed component or root cause.

A maintenance action triggered by relevant observed equipment condition under appropriate assessment criteria, rather than simply by elapsed calendar time.

A proposed explanation for the failure mechanism that must be tested against suitable evidence, not established merely by replacing a named part.

An authorized return-to-service process including the relevant protective functions, functional checks, records and handover under actual equipment and site requirements.

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.

A controlled record of asset conditions, faults, actions and evidence supporting comparisons and investigation rather than merely storing the latest replacement invoice.

The relevant pressure-loaded area for the stated direction, with the rod area subtracted on the annular side of a double-acting cylinder.

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 describes force intensity while flow describes volume rate; confusing them can give an incorrect explanation for actuator force or speed.

Formation and collapse of vapor cavities when local liquid pressure becomes unsuitable, distinct from simply drawing free air into a system.

An engineered combination managing the specified load and failure conditions, which cannot be replaced by assuming any simple throttle safely holds a suspended mass.

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.

The signed difference between the stated reference and measured value, whose interpretation requires the actual loop convention and operating context.

The specified interval over which a sensor is intended to measure, distinct from its resolution, accuracy and allowed operating environment.

The value presented to the controller by its configured input channel, which may differ from a local process-gauge observation and requires appropriate diagnosis.
