API SIEE - Source Inspector Electrical Equipment
Practice Exam
1. A source inspector arrives at a transformer manufacturer's facility and
discovers that the vendor has completed the winding insulation test
before the purchaser's mandatory hold point was released. What is the
most appropriate response?
A. Accept the test because it passed
B. Request that the test report be signed retrospectively
C. Document the hold-point violation and seek an approved disposition, including
retesting where required
D. Approve shipment if the transformer looks satisfactory
Answer:
C) Document the hold-point violation and seek an approved disposition,
including retesting where required
Rationale:
A hold point prevents work from proceeding without the specified authorization.
Successful test results do not automatically eliminate the contractual requirement for
purchaser participation. The inspector should document the deviation and obtain an
authorized disposition before releasing the equipment.
2. A switchgear supplier proposes replacing a specified copper busbar
with an aluminum busbar because of material shortages. The supplier
claims both materials have similar electrical performance. What should
the inspector do?
A. Approve the substitution based on the supplier's assurance
B. Require formal engineering review and purchaser approval before accepting the
substitution
C. Accept the substitution if the enclosure dimensions remain unchanged
D. Reject the entire manufacturing facility permanently
,Answer:
B) Require formal engineering review and purchaser approval before
accepting the substitution
Rationale:
Copper and aluminum differ in conductivity, thermal expansion, connection
requirements, and mechanical characteristics. A material substitution can affect
temperature rise and short-circuit performance. Only an authorized technical review
can establish whether the proposed change satisfies the purchase requirements.
3. During a motor manufacturing audit, the inspector discovers that
calibration certificates for several winding resistance meters expired two
months earlier. What is the best action?
A. Accept the measurements because the instruments still operate
B. Replace the recorded values with estimated readings
C. Ignore the issue because resistance measurements are simple
D. Quarantine affected results and evaluate the instruments' calibration status and
required retesting
Answer:
D) Quarantine affected results and evaluate the instruments' calibration status
and required retesting
Rationale:
Measurement traceability is essential when test results establish product conformity.
Expired calibration does not prove that an instrument is inaccurate, but it creates
uncertainty about its measurement status. The inspector should require an impact
assessment and appropriate verification or retesting.
4. A supplier's inspection and test plan identifies a witness point for a
circuit breaker mechanical endurance test. The purchaser's inspector
receives proper notification but cannot attend. What should happen?
A. Follow the approved witness-point waiver or release procedure and retain
objective test records
B. Stop production indefinitely
C. Convert the witness point automatically into a hold point
,D. Delete the test from the quality plan
Answer:
A) Follow the approved witness-point waiver or release procedure and retain
objective test records
Rationale:
A witness point ordinarily provides an opportunity to observe a defined activity. Its
release requirements depend on the approved inspection and test plan and contract.
The supplier must still perform the required test and maintain verifiable records.
5. A purchasing specification requires a transformer to meet a particular
standard edition, but the supplier's drawings reference an earlier edition.
What should the inspector do?
A. Accept the earlier edition because it is familiar
B. Reject the transformer without further investigation
C. Identify the discrepancy and request documented technical resolution before
acceptance
D. Allow the supplier to select whichever edition is cheaper
Answer:
C) Identify the discrepancy and request documented technical resolution
before acceptance
Rationale:
Different standard editions may contain different design and testing requirements.
The contractual edition establishes the applicable compliance baseline unless a
formal change is approved. The inspector should ensure that the supplier's design
documents are reconciled with the purchase specification.
6. During an audit, a manufacturer provides excellent final test reports
but cannot produce records showing that critical components were
inspected upon receipt. What is the primary quality concern?
A. The equipment will necessarily fail immediately
B. The quality system lacks objective evidence of required incoming-material
controls
C. The supplier's building is too small
, D. The final test reports are automatically fraudulent
Answer:
B) The quality system lacks objective evidence of required incoming-material
controls
Rationale:
Incoming inspection helps prevent incorrect or defective materials from entering
production. Final testing may not reveal every component-related defect. Missing
records indicate a gap in quality assurance that requires evaluation and corrective
action.
7. A source inspector is assigned to a supplier where a close relative
manages the quality department. What is the most appropriate
professional action?
A. Conceal the relationship
B. Reduce the inspection scope
C. Ask the relative to sign the inspection reports
D. Disclose the potential conflict of interest and follow the employer's independence
requirements
Answer:
D) Disclose the potential conflict of interest and follow the employer's
independence requirements
Rationale:
Source inspectors must exercise impartial professional judgment. Personal
relationships can create actual or perceived conflicts of interest. Disclosure allows
the responsible organization to determine appropriate safeguards or reassignment.
8. A manufacturer offers the inspector an expensive gift immediately
before a critical factory acceptance test. What should the inspector do?
A. Decline the gift and follow the applicable ethics and reporting policy
B. Accept it if the equipment passes
C. Accept it but omit it from the inspection report
D. Request cash instead
