Inspection & Testing (ET105) study plan
Inspection & Testing (ET105) · Give each week a clear focus.
8 weeks · About 6 hours per week
Inspection Fundamentals and Terminology & Non-Destructive Examination Methods
Define and correctly distinguish at least 25 core inspection terms (discontinuity vs. defect, indication vs. flaw, sensitivity, resolution) from memory
Map each of the five common NDE methods (VT, PT, MT, UT, RT) to the discontinuity types it detects and its principal limitations
Explain the inspection lifecycle from test plan through disposition, identifying where each NDE method enters
Solve 20 terminology and method-selection practice items and log every miss with the reason
Your checkpoint
A one-page method-selection matrix (method × discontinuity type × limitation) plus a scored 20-item terminology quiz with error log
Non-Destructive Examination Methods
Describe the physical principle, setup, and signal interpretation for PT and MT, including penetrant types and magnetization methods
Describe the physical principle, transducer/beam behavior, and display interpretation for UT, including angle-beam and straight-beam applications
Describe radiation sources, film vs. digital imaging, and image-quality indicators for RT
Compare NDE methods on sensitivity, part geometry constraints, surface preparation, and cost, and justify a method choice for three given scenarios
Complete 30 NDE practice items with at least 80% accuracy
Your checkpoint
A written justification of NDE method selection for three worked scenarios, each citing principle, limitation, and rejection criteria
Non-Destructive Examination Methods & Destructive and Mechanical Testing
Explain eddy current and other supplementary NDE techniques at a recognition level, including what each is and is not suited for
Define the standard mechanical tests (tension, hardness, impact, bend, fatigue) and state what property each measures
Interpret a stress-strain curve to identify yield, ultimate strength, elongation, and elastic modulus
Differentiate destructive test specimen preparation requirements and how specimen orientation affects results
Your checkpoint
An annotated stress-strain curve with all key points labeled plus a table mapping each mechanical test to the property measured and a typical acceptance metric
Destructive and Mechanical Testing & Visual and Dimensional Inspection
Explain hardness scale conversions and the conditions under which conversion between scales is and is not valid
Describe impact-test transition behavior and what fracture appearance reveals about toughness
Identify the dimensional characteristics verified by common gauges and instruments and the correct instrument for each measurement class
Perform tolerance stack reasoning on three worked dimensional examples and determine conformance
Complete 25 mixed destructive/dimensional items at 80% or better
Your checkpoint
Three fully worked dimensional conformance calculations with tolerance stacks, plus a 25-item scored quiz with error log
Visual and Dimensional Inspection & Codes, Standards, and Regulatory Requirements
Apply surface-finish and weld/visual acceptance attributes to judge conformance in five written case descriptions
Distinguish codes, standards, and specifications by function and identify who enforces each
Explain how a standard becomes a regulatory requirement and what that means for an inspector's authority
Locate and apply the precedence rules when a drawing, a specification, and a code conflict
Summarize the inspector's records and traceability obligations under typical quality-system requirements
Your checkpoint
A conflict-resolution write-up for three scenarios where drawing, specification, and code disagree, each stating the governing document and rationale
Test Equipment, Calibration, and Measurement Uncertainty & Sampling, Test Procedures, and Data Recording
Explain calibration traceability, calibration intervals, and the difference between calibration and verification
Compute measurement uncertainty contributions and state a result with proper significant figures and uncertainty
Design a sampling plan for a stated lot size and acceptance number, and explain the risk of each sampling choice
Write a step-by-step test procedure that another inspector could execute without clarification
Record raw data, corrections, and observations so the record is independently reconstructible
Your checkpoint
A complete test procedure for one inspection task, including sampling plan, calibration status, uncertainty statement, and a filled data-recording form
Acceptance Criteria, Reporting, and Documentation & Safety, Ethics, and Quality Assurance
Write acceptance/rejection dispositions that cite the specific criterion and the objective evidence
Draft a nonconformance report containing description, requirement, evidence, disposition, and corrective action
Identify ethical conflicts (pressure to pass nonconforming material, incomplete records, undisclosed calibration lapse) and state the correct action for each
List the safety controls for the physical hazards of each NDE method, including radiation and high-voltage/mechanical hazards
Assemble a complete inspection report package meeting documentation and traceability requirements
Your checkpoint
A full mock inspection report package: report, one nonconformance report, and a signed disposition, reviewed against a self-built checklist

Re-take every weekly quiz and reduce total error count by at least 50% versus first attempt
Complete two full-length timed practice exams under exam conditions and score each by domain
Re-teach the three weakest domains from memory in written summaries without notes
Close every open item in the error log by writing the correct reasoning for each
Finalize a one-page formula and criteria reference sheet for last-day review
