01 · APPEARANCE
Surface and finish defects
Scratches, scuffs, sink marks, waviness, colour mismatch, paint blemishes or contamination.
Check lighting conditions, reference samples, surface zone and agreed acceptance criteria.Recognize the defect. Understand the risk.
A public, illustrative guide to common automotive component and assembly non-conformities. These recreated visuals and descriptions are generic examples — not customer drawings, confidential standards or a company-specific defect catalogue.

COMMON NON-CONFORMITY FAMILIES
Typical defects across parts and assemblies.
The examples below help visitors recognize categories of issues. Actual acceptance criteria depend on the approved product definition, applicable specification, inspection method and customer requirements.
02 · DIMENSIONAL
Geometry and dimensional variation
Out-of-tolerance dimensions, distortion, warpage, hole-position deviation or unstable geometry.
Compare measurement results with the drawing, datum strategy and measurement-system capability.
03 · FIT & FLUSH
Gaps, flushness and alignment
Uneven gaps, proud or recessed surfaces, misalignment, interference or inconsistent fit.
Check the assembly condition, neighbouring parts, adjustment sequence and tolerance stack-up.
04 · ASSEMBLY
Fixation and interface defects
Broken clips, missing fasteners, loose joints, poor retention, interference or incorrect assembly.
Verify part presence, interface condition, assembly method and required retention or torque.
05 · MATERIAL / STRUCTURE
Cracks, breaks and material anomalies
Cracks, fractures, deformation, porosity, burrs, delamination or other material/process anomalies.
Contain affected parts and use the relevant technical inspection or laboratory method.
06 · FUNCTION
Functional or performance failure
Jamming, abnormal noise, leakage, poor movement, weak retention or failure to meet functional intent.
Reproduce the failure under defined conditions and record measurable test evidence.A CONSISTENT RESPONSE
From detection to verified corrective action.
1 · IDENTIFY
Describe
Record the part, location, condition, evidence and affected quantity.
2 · PROTECT
Contain
Prevent suspect parts from reaching the next operation or customer.
3 · UNDERSTAND
Analyse
Confirm the cause using measurements, comparisons and controlled tests.
4 · SUSTAIN
Verify
Validate corrective action and monitor for recurrence.
