질문 # 12
Positive-pressurization and purging are based on the principle that an enclosure or room located in a classified location can:
정답：C
설명：
The correct answer isC. In hazardous or classified locations, positive pressurization and purging protect electrical equipment by preventing the surrounding flammable atmosphere from entering the enclosure. The operating principle is that the enclosure, cabinet, or room is supplied withclean air or an inert gasat a pressure and flow rate high enough to keep hazardous gas or vapor out before and during equipment operation. This allows equipment that might otherwise not be suitable for direct exposure to a classified atmosphere to operate safely when the purge and pressure conditions are maintained.
From an API source-inspection perspective, this aligns with the guide's emphasis on verifying compliance with thespecified protection method, nameplate data, project drawings, and applicable hazardous-area requirements during inspection and surveillance. The inspector's concern is not simply whether the enclosure exists, but whether the correct protective concept has been applied and supported by proper fabrication, testing, and documentation. Options A and B describe the hazardous atmosphere itself, not the protection principle. Option D is incorrect because normal arcing devices still require a suitable protection method; pressurization does not rely on relays arcing normally.
질문 # 13
Machine vibration measurement using non contacting probes are taken:
정답：A
설명：
The correct answer isD. In rotating electrical equipment,non-contacting probesnormally refer toproximity probesthat are mounted in or at thebearing housingsto monitorshaft relative vibration. These probes do not touch the shaft; instead, they sense shaft motion relative to the bearing housing. In practice, radial vibration is usually monitored in thehorizontal and vertical directions, and where applicable axial movement is also monitored using an axial probe arrangement. That makes option D the only technically correct choice.
The other options are not consistent with standard vibration measurement practice. Measurements taken on thebaseplateorframeare generally made with contact sensors such as accelerometers or velocity pickups, not non-contacting probes. Option B is incorrect because vibration is not defined as being measured "on the shaft at 1.2 times the running speed" as a standard probe location criterion. The API guide includeselectric motors over 500 HPamong its covered equipment categories and emphasizessource inspection and quality surveillance activitiestied to applicable standards, testing, and verification during manufacture.
질문 # 14
According to API 541, during a witness or observed test of a 500 hp kW induction motor, the purchaser shall have the right to observe all the following, which may occur due to the expected or unexpected part or event of the test except:
정답：C
설명：
The correct answer isC. disassembly of the rotor. In API 541 witness or observed testing practice for large induction motors, the purchaser has the right to observe activities that may become necessary as part of the test process, includingdismantling of the motor, inspection of the motor, and reassembly of the motor. These actions are directly related to investigating test issues, verifying construction, checking condition after a test event, and confirming that the motor is properly restored following inspection.
The rotor itself is normally treated as a major internal component of the motor, butdisassembly of the rotoris not a standard purchaser observation right described in the same way. A rotor may beremovedor examined if necessary, but "disassembly of the rotor" suggests taking apart the rotor assembly itself, which is not the expected wording or normal scope of witness rights during standard API 541 test observation. For source inspection purposes, this distinction matters because inspectors must recognize the difference between observation of motor-level teardown and reassembly versus unnecessary or nonstandard internal component disassembly. Therefore,Cis the exception.
질문 # 15
Who should the Source Inspector notify if they believe that product quality may be compromised by schedule pressures?
정답：A
설명：
The correct answer isB. The inspection coordinator. In the API source inspection framework, the inspector's role is to independently observe, verify, document, and communicate quality-related concerns through the established inspection reporting chain. When schedule pressure appears likely to compromise product quality, the issue must be escalated to theinspection coordinator, because that person manages inspection execution, communication flow, and coordination between the purchaser, supplier, and inspection function. This keeps the inspector independent and ensures the concern is addressed formally rather than informally.
The other options are less appropriate. TheMaster Scheduleris responsible for planning and timing, not for controlling inspection escalation. Theshop QA Managerbelongs to the supplier's organization, so reporting directly there could weaken the inspector's independent reporting path. TheProject Managermay ultimately need awareness, but the normal and correct first notification route in source inspection administration is through the inspection coordinator. This approach aligns with API source inspection practice, where quality threats, deviations, and risks are communicated through designated inspection channels so that corrective action, hold points, and surveillance priorities can be managed properly.
