Inspection & Test

Owned by quality rather than production: optical and X-ray inspection, metal detection, checkweighing, coordinate measurement, leak and functional test. On an electronics or aerospace line this can be a third of the floor, and none of it makes product.

14 types, and what a survey records

Equipment type	Recorded for each one
AOI / Optical Inspection	Stage · Inline or offline
X-ray Inspection	Max sample size · Imaging · Tube voltage · Tube hours / expected life · Radiation protection · What happens on failure
ICT / Flying Probe Test	Type · Test time per board · Fixtures held · Test coverage · Calibration / verification interval · What happens on failure
Burn-in / Environmental Chamber	Chamber volume · Temperature range · Humidity range · Capability · Calibration / verification interval · Refrigeration service interval
Metal Detector / X-ray Inspection	Type · Aperture size · Sensitivity · Test piece checks · Reject verification · What happens on failure
Checkweigher	Weight range · Accuracy · Packs per minute · Legal for trade / average weight · Calibration / verification interval · Feedback to filler
CMM / Inspection Machine	Measuring volume · Accuracy / MPE · Probe · Environment · Calibration / verification interval · Programs held
SPI / Solder Paste Inspection	Max board size · Resolution · Cycle time · Feedback to printer · What happens on failure
Functional Test (FCT)	Test time per unit · Fixtures held · Functional coverage · Results logged · Calibration / verification interval · What happens on failure
Transformer / Motor Test Rig	Max rating tested · Test voltage · Tests performed · Calibration / verification interval · Safety interlocks
Leak Test Rig	Method · Detectable leak rate · Test pressure · Cycle time · Calibration / verification interval · Master / calibrated leak used
Test Rig / Dynamometer	Max power absorbed · Max speed · Max torque · Absorber · Energy regenerated to site · Calibration / verification interval
Vision Inspection System	Cameras · Resolution / smallest defect · Parts per minute · False reject rate · Lighting · What happens on failure
NDT / Ultrasonic Inspection	Method · Standards worked to · Operator qualification · Calibration / verification interval · Reference blocks / calibration pieces

Anything not listed is recorded under “Other Inspection & Test” — no list of industrial equipment is ever finished, and a register that pretends otherwise forces people to pick something untrue.
