The TPFP Technicien en Maintenance Industrielle is the metallurgy branch professional title (Level 4 / Bac, RNCP39210, UIMM / CPNE) for industrial multi-technology maintenance. Evaluated in French through workplace evidence and simulated practical scenarios before a commission d'évaluation and awarded by a jury paritaire (50% unions, 50% employers), it covers three competence blocks: preventive maintenance, corrective maintenance, and improvement contribution. This 100-question practice bank is an English-language MCQ study adaptation for revising technical formulas, diagnostics, standards, and reliability methods; it is not an official translation and cannot replace practical workshop assessment.

1A maintenance technician conducts a periodic vibration survey on a 45 kW, 1,500 rpm induction motor mounted on a rigid foundation in a steel rolling shop. According to ISO 10816-3 (Group 2, rigid support), the measured broadband overall vibration velocity RMS is 3.2 mm/s. How should this measurement be evaluated and what maintenance action is required?

A.The machine is in Zone C (2.8 to 4.5 mm/s): vibration is unsatisfactory for continuous long-term service; the machine may run temporarily while a corrective intervention is planned

B.The machine is in Zone A (< 1.4 mm/s): vibration corresponds to newly commissioned equipment in perfect operating condition requiring no action

C.The machine is in Zone B (1.4 to 2.8 mm/s): vibration is fully acceptable for unrestricted long-term operation without any scheduling adjustment

D.The machine is in Zone D (> 4.5 mm/s): vibration severity is dangerous and requires an immediate emergency tripping of the motor to prevent catastrophic breakdown

Explanation: Under ISO 10816-3 for medium-sized industrial machines (15 kW to 300 kW, Group 2) on rigid foundations: Zone A is < 1.4 mm/s RMS (new machines), Zone B is 1.4 to 2.8 mm/s (unrestricted continuous operation), Zone C is 2.8 to 4.5 mm/s (restricted continuous operation / alert threshold, where remedial action must be scheduled), and Zone D is > 4.5 mm/s (danger threshold where damage is imminent). A level of 3.2 mm/s falls squarely in Zone C.

2A technician carries out systematic preventive re-lubrication on an exhaust fan driven by a spherical roller bearing (reference 22314). The bearing has an outside diameter D = 150 mm and a width B = 51 mm. Using the standard industrial re-lubrication quantity formula Q = 0.005 × D × B (in grams), how much grease should be injected into the housing?

A.15.3 g

B.38.3 g

C.76.5 g

D.150.0 g

Explanation: Applying the standard SKF / ISO relubrication formula Q = 0.005 × D × B (where D is outside diameter in mm and B is width in mm): Q = 0.005 × 150 × 51 = 38.25 g ≈ 38.3 g. Injecting this precise quantity ensures hydrodynamic separation of rolling elements without causing over-greasing and thermal runaway.

3Before replacing a drive belt on a multi-technology conveyor, a technician carries out an electrical lockout/tagout (consignation) under standard NF C 18-510. Which sequence correctly describes the mandatory procedure for Step 4: Voltage Absence Verification (Vérification d'Absence de Tension - VAT)?

A.Use a standard digital multimeter set to 750 V AC to probe between phase 1 and ground only, without prior self-testing

B.Switch off the main circuit breaker and immediately verify zero current using an AC clamp ammeter on each phase

C.Test a dedicated VAT device conforming to NF EN 61243-3 immediately before use, verify voltage absence between all phase conductors and between each phase and earth, and immediately re-test the VAT device

D.Check that the green panel pilot indicator light is off and touch the bare copper busbars with an insulated screwdriver

Explanation: NF C 18-510 strictly requires that VAT is carried out using a dedicated Voltage Absence Tester compliant with NF EN 61243-3 (never a standard multimeter). The device must be tested on a known source or via its integrated tester immediately before the measurement, used to verify absence of voltage between all phases and between each phase and PE/earth, and re-tested immediately after to prove it did not fail during the test.

4According to the European standard AFNOR NF EN 13306, which of the following operations is classified strictly as systematic preventive maintenance (maintenance systématique)?

A.Replacing a hydraulic proportional valve spool because acoustic ultrasound signals show internal bypass leakage

B.Cleaning an air-handling filter after an optical differential pressure switch signals that ΔP exceeds 250 Pa

C.Replacing a machine spindle bearing after an FFT vibration spectrum reveals a distinct inner raceway defect frequency

D.Replacing all hydraulic suction filters and synthetic gearbox lubricant every 4,000 running hours according to the manufacturer schedule, irrespective of measured condition

Explanation: AFNOR NF EN 13306 defines systematic preventive maintenance as preventive maintenance carried out in accordance with an established time schedule or a predetermined number of units of use, without previous condition investigation. Replacing filters and oil strictly every 4,000 hours is purely systematic.

5A pinch-roll drive in a cold-rolling mill rotates at n = 1,200 rpm (rotational frequency fr = 20 Hz). The support shaft is guided by a deep groove ball bearing with N = 8 balls, contact angle α = 0°, ball diameter d = 12 mm, and pitch diameter Dm = 60 mm. What is the outer ring defect pass frequency (BPFO)?

A.64.0 Hz

B.96.0 Hz

C.80.0 Hz

D.160.0 Hz

Explanation: The Ball Pass Frequency Outer ring formula is BPFO = (N / 2) × fr × [1 - (d / Dm) × cos α]. Substituting the values: BPFO = (8 / 2) × 20 × [1 - (12 / 60) × cos 0°] = 4 × 20 × [1 - 0.20] = 80 × 0.80 = 64.0 Hz. A spectral peak at 64 Hz and its harmonics indicates a fatigue crack or spalling on the outer raceway.

6During a preventive electrical inspection of a 7.5 kW 400 V three-phase induction motor, a technician measures the phase winding resistances across disconnected terminal blocks (U1-U2, V1-V2, W1-W2) with a calibrated milliohmmeter. The readings are: U1-U2 = 1.82 Ω, V1-V2 = 1.84 Ω, and W1-W2 = 3.12 Ω. What does this measurement indicate?

A.The windings are balanced within normal 5% industrial tolerance and the motor is ready for service

B.Phase W has an abnormally high resistance (> 70% unbalance), indicating a loose internal crimp, failing terminal connection, or partial open circuit that will cause severe current imbalance

C.The motor has a direct short-circuit to earth on phase W requiring an immediate insulation test at 24 V DC

D.Phase W has shorted turns, which always increases measured DC winding resistance

Explanation: Healthy three-phase stator windings must exhibit balanced DC resistance across all three phases within ±2% to 5%. A reading of 3.12 Ω compared to ~1.83 Ω represents an unbalance exceeding 70%, caused by a poor connection, broken parallel stranding, or oxidised terminal stud. Energizing the motor would cause severe phase current unbalance, vibration, and thermal destruction.

7On an automated stamping cell, a technician inspects the main pneumatic conditioning unit (FRL). The filter bowl is half-full of milky water emulsion, and the pressure gauge dial fluctuates wildly between 3.5 bar and 6.2 bar during cylinder cycling. What is the root cause and immediate preventive action?

A.The lubricator is empty; oil must be poured directly into the pneumatic supply hose

B.The system pressure is too high; the main safety relief valve must be permanently wired shut

C.The automatic condensate float drain is fouled and jammed closed, and the upstream refrigerated air dryer is failing or bypassed; the drain must be serviced and the pressure regulator diaphragm inspected

D.The air cylinders have oversized exhaust mufflers that generate backpressure into the supply line

Explanation: Accumulation of milky liquid indicates moisture condensation and emulsified oil caused by an upstream dryer failure or saturated pre-filters, coupled with a jammed automatic float drain that fails to purge water. Water carryover into the regulator damages its rolling diaphragm and valve poppet, causing pressure hunting and downstream component corrosion.

8During a certified infrared thermographic survey (per standard NF EN 13306 / APSAD D19 guidelines) of a main 400 V power distribution cabinet operating under 80% steady load, phase L2 on an incoming molded-case circuit breaker (MCCB) terminal displays 82 °C, while phases L1 and L3 display 44 °C (ambient temperature 24 °C). How is this temperature difference (ΔT = 38 °C between phases) classified?

A.Normal thermal gradient due to natural convection inside enclosed switchboards

B.Minor anomaly (Priority 3): schedule inspection at the next biennial plant turnaround in 24 months

C.Moderate anomaly (Priority 2): monitor trend with a handheld contact pyrometer every month

D.Critical anomaly (Priority 1): severe defect with immediate risk of insulation melting or fire; de-energize and torque or replace the degraded terminal immediately

Explanation: Under thermographic inspection standards (such as APSAD D19 / NETA), a temperature differential ΔT between phases under identical load of > 30 °C indicates a critical defect (Priority 1). The high resistance joint at 82 °C is in thermal runaway, posing an imminent risk of cable insulation failure, terminal fire, and arc-flash fault.

9A technician checks the rotational speed of a 4-pole, 50 Hz three-phase asynchronous motor driving a heavy hydraulic power pack using an optical laser tachometer. The measured rotor speed is n = 1,440 rpm. What are the motor's synchronous speed (ns), fractional slip (g), and rotor induced frequency (fr)?

A.ns = 1,500 rpm; g = 0.04 (4.0%); fr = 2.0 Hz

B.ns = 3,000 rpm; g = 0.52 (52.0%); fr = 26.0 Hz

C.ns = 1,500 rpm; g = 0.06 (6.0%); fr = 3.0 Hz

D.ns = 1,440 rpm; g = 0.00 (0.0%); fr = 50.0 Hz

Explanation: Synchronous speed for a 4-pole motor (p = 2 pairs) at 50 Hz is ns = (60 × f) / p = (60 × 50) / 2 = 1,500 rpm. Slip is g = (ns - n) / ns = (1,500 - 1,440) / 1,500 = 60 / 1,500 = 0.04 (4.0%). The rotor induced electrical frequency is fr = g × f = 0.04 × 50 Hz = 2.0 Hz.

10Under French standard AFNOR NF X 60-010 (defining the 5 levels of industrial maintenance), which operation specifically exemplifies Level 2 maintenance (Maintenance de niveau 2)?

A.Simple visual checks, cleaning, and fluid top-ups performed by the machine operator using built-in indicators without opening enclosures

B.Replacement of standard consumable parts, fuses, wear components, and drive belts using simple procedures and standard hand tools by an authorized technician

C.Complex on-site diagnostics, dynamic laser shaft balancing, and modular PLC electronic board replacement requiring specialized diagnostic instruments

D.Full factory overhaul, remanufacturing, and compliance reconstruction performed by the original equipment manufacturer (OEM) in an external facility

Explanation: AFNOR NF X 60-010 defines Level 2 maintenance as minor actions performed by qualified personnel using simple procedures, replacing standard wear parts (belts, fuses, filters, standard sensors) with basic hand tools. Level 1 is operator maintenance, Level 3 is complex on-site diagnostic/modular repair, Level 4 is major overhaul in a workshop, and Level 5 is manufacturer rebuilding.

TPFP Technicien Maintenance Industrielle: Suggested Study Strategy

1Master AFNOR NF EN 13306 maintenance terminology: clearly distinguish preventive (systematic vs conditional) from corrective maintenance, and curative repair (réparation définitive) from palliative temporary fixes (dépannage provisoire).

2Practice multi-energy isolation: review the 5-step electrical lockout protocol under NF C 18-510 (séparation, condamnation, identification, VAT with dedicated tester, and MALT/CC), plus mechanical, pneumatic, and hydraulic pressure dissipation.

3Memorize core fluid power formulas: pneumatic/hydraulic cylinder push force F_push = p × S_piston and pull force F_pull = p × (S_piston - S_rod), and pump heat dissipation Heat (kW) ≈ (p × Q) / 600.

4Review reliability indicators and formulas: MTBF = Total Operating Time / Number of Failures, MTTR = Total Repair Time / Number of Repairs, Operational Availability Ao = MTBF / (MTBF + MTTR), and AMDEC Criticality C = G × F × D.

5Understand vibration condition monitoring: review ISO 10816-3 broadband velocity RMS zones for rigid vs flexible supports, and calculate bearing defect frequencies (BPFO, BPFI).

6Prepare for continuous improvement discussions: learn how to construct and interpret Pareto (80/20) downtime charts and propose concrete engineering upgrades (bearing seals, centralized lubrication, Poka-Yoke error-proofing).

Frequently Asked Questions

What is the official evaluation format of the TPFP Technicien en Maintenance Industrielle?

Under the RNCP39210 standard, assessment is carried out by an evaluation commission (commission d'évaluation) against the branch référentiel de certification in real or simulated work situations (situation de travail réelle ou reconstituée). These practical evaluations are supplemented where necessary by oral or written questioning. Final certification is decided by a paritary jury (jury paritaire) composed 50% of employee-union representatives and 50% of employer-organization representatives by delegation of the CPNE-FP de la métallurgie.

Does this English-language practice bank simulate the real certification test?

No. The official certification is performance-based, delivered through workplace or training-centre practical situations, and conducted in French. This 100-question practice test is an English-language MCQ study adaptation for revising technical engineering formulas, schematic reading, safety regulations, and diagnostic methodology. It is not an official translation and cannot substitute for hands-on practical competence before the paritary commission.

What is the difference between this branch TPFP (RNCP39210) and the state Titre Professionnel (RNCP41536)?

The TPFP (RNCP39210) is a metallurgy industry branch title certified by the UIMM, FEDEREC, and CPNEF Papiers Cartons, organized around three competence blocks (preventive, corrective, and improvement maintenance per AFNOR NF EN 13306) and evaluated by a joint employer-union paritary jury. The Titre Professionnel TMI (RNCP41536) is a state title issued by the Ministère du Travail, organized across four competence blocks and evaluated through a standardized 7h 20min session featuring a 5h 45min practical scenario (MSP) before a ministry-accredited trade jury.

What happened to the historic CQPM Technicien de Maintenance Industrielle (CQPM 137)?

The historic CQPM 137 (MQ 1996 01 37 / RNCP35282) was not discontinued; rather, the CPNE-FP de la métallurgie decided on 10 February 2025 that the certification evolved in legal nature into a Titre à finalité professionnelle (TPFP), effective 1 April 2025, under the active France Compétences fiche RNCP39210 (registered through 27 June 2029 with deliveries possible through 2033).

Can private individual candidates register directly for this certification?

No. France Compétences fiche RNCP39210 specifies that individual candidature (candidature individuelle) is not an authorized access route. Access is exclusively open through apprenticeship contracts (apprentissage), professionalisation contracts (professionnalisation), continuous vocational training pathways (formation continue, capped at 18 months), and Validation des Acquis de l'Expérience (VAE).
