質問 # 49
According to API 541, the combined runout for areas on the shaft that are to be observed by radial vibration probes shall not exceed:
正解：D
解説：
The correct answer isD. In API 541, when a motor shaft is monitored usingradial vibration probes, the probe- observed shaft surface must meet a strictcombined runoutlimit so that the vibration reading reflects actual machine vibration rather than shaft surface irregularity, eccentricity, or electrical and mechanical runout effects. API 541 sets this limit at25% of the allowed unfiltered peak-to-peak vibration amplitude or 6.4 µm
0.25 mils, whichever is greater. This requirement is important because excessive runout can distort probe signals and produce misleading vibration data during shop testing and acceptance.
From a source inspection standpoint, this is a critical verification item during motor testing for large rotating equipment. If the shaft finish and probe track are not within the required runout limit, the vibration measurements cannot be relied on for acceptance decisions. The API guide includeselectric motors over 500 HPas a covered equipment category and emphasizes inspection and surveillance activities tied to applicable standards, testing, and verification of compliance during manufacture. Therefore,option Dis the correct API
541 requirement.
質問 # 50
According to IEEE C57.12.00, a durable, metal, name plate shall be affixed to each transformer by the:
正解：A
解説：
The correct answer isA, manufacturer. IEEE C57.12.00 requires that each transformer be provided with adurable metal nameplateattached by themanufacturer. This requirement exists because the nameplate is a permanent identification and rating record for the transformer. It contains critical information such as manufacturer identity, serial number, kVA rating, voltage ratings, frequency, impedance, cooling class, temperature rise, and other essential design and operating data. Since this information originates from the transformer design and production records, responsibility for affixing the plate belongs to the manufacturer, not to the owner, purchaser, or inspector.
From an API source inspection perspective, the nameplate is an important verification point during final inspection. The source inspector checks that the plate is present, permanently attached, legible, and consistent with the approved data sheet, purchase order, drawings, and test records. A missing, incorrect, or improperly marked nameplate can create traceability problems and may result in nonconformance. Therefore, the correct party responsible for affixing the durable metal nameplate is themanufacturer, makingAthe verified answer.
質問 # 51
Which of the following tools is used for inspection of coating?
正解：B
解説：
The correct answer isAbecause the most common and direct inspection instrument used for acoating after applicationis thedry film thickness DFT gauge. In source inspection and quality surveillance, coating verification typically includes checking whether the applied paint or protective coating has achieved the specified thickness range. That is a fundamental acceptance point because coating that is too thin may fail prematurely, while coating that is too thick may crack, blister, or cure improperly. In practical inspection language, the option says "Dry film thickness DFT," but it clearly refers to theDFT measuring gauge/toolused by inspectors.
The other options are related but not the best answer. Adigital surface profile gaugeandsurface profile replica tapeare mainly used to evaluate thesurface profile of blasted steel before coating, not the final dry coating thickness itself. Anultrasonic thickness meteris generally used for base material wall thickness measurement, not routine paint-coating inspection. The API guide covers source inspection and surveillance of manufacturing activities and stresses verification against specifications, records, and inspection points for covered equipment.
質問 # 52
What method is used to verify tightness of accessible bolted electrical connections?
正解：B
解説：
The correct answer isD. Calibrated torque wrench. In source inspection and quality surveillance of electrical equipment, the accepted method for verifying the tightness ofaccessible bolted electrical connectionsis to check them using aproperly calibrated torque wrenchagainst the manufacturer's specified torque values. This is the most reliable way to confirm that the connection has been tightened to the required mechanical and electrical standard. Proper torque is critical because under-tightening can produce high resistance, localized heating, arcing, and eventual failure, while over-tightening can damage threads, connectors, lugs, or bus material.
The other options do not provide a true verification method.Compression of the lock-nutis not a recognized measurement of electrical connection tightness.Visual inspection of torque markingsmay indicate that tightening was performed, but it does not independently verify the actual torque achieved.Verification of an assembly check sheetonly confirms that work was recorded, not that the joint currently meets the specified torque requirement. Therefore, for source inspectors evaluating electrical assemblies, the correct and defensible method is use of acalibrated torque wrenchto verify accessible bolted electrical connections.
質問 # 53
When might a resident source inspector be required at a shop during manufacture and fabrication?
正解：A
解説：
The correct answer isA. In API source inspection practice, the decision to assign aresident source inspectoris driven primarily by therisk level of the equipment or fabrication activity. When the risk assessment identifies an item ashigh or highest risk, increased surveillance may be necessary because the consequences of defects, missed hold points, schedule slippage, or nonconformance can be significant. A resident inspector provides continuous or frequent monitoring of manufacturing progress, verification of critical stages, review of records, and immediate reporting of issues that could affect quality, cost, or delivery.
Option B is not sufficient by itself. Being sourced from a foreign vendor may affect logistics or planning, but it does not automatically justify a resident inspector. Option C is based on convenience, not inspection need.
Option D may create project pressure, but a busy shop or tight schedule alone is not the primary criterion for resident assignment.
The API approach is risk-based: surveillance intensity, including the possible need for a resident inspector, is determined by thecriticality and risk classificationof the equipment and the potential impact of nonconformance during manufacture.
