Asset identification
Confirm the magnetic separators included in the visit and the equipment context available at the time of inspection.
Food-plant field service
Magnetic separator verification, documented properly.
On-site visual inspection, repeatable gauss measurements, and per-unit records for magnetic traps and separators—without turning one reading into a claim it cannot support.

What the visit includes
Useful evidence starts before the meter is switched on.
A defensible record identifies the equipment, the instrument, the measurement locations, and the criteria used to interpret the result.
Visual inspection
Document accessible condition and observed exceptions before any measurement is taken.
Gauss measurements
Record magnetic flux-density readings at defined, repeatable test locations using a calibrated gauss meter.
Findings and records
Provide a per-unit result record and identify exceptions against the facility's defined criteria or documented baseline.
Use the right measurement
Gauss and pull force answer different questions.
Gauss testing
Measures magnetic flux density at a point. The result depends on probe orientation, test location, surface condition, geometry, and temperature.
Pull-force testing
Measures the force required to separate a defined test piece from the magnet under a defined setup. It is not interchangeable with a gauss reading.
Important: Neither method should be converted into the other without a validated basis. A single peak reading also does not prove capture of every hazardous fragment under every process condition.
Build the record
Make the next reading comparable to this one.
Measurement history becomes useful when the method and context stay visible.
- Asset ID, location, and separator configuration
- Meter model, serial number, and calibration evidence
- Probe, fixture, orientation, and identified test points
- Raw readings and units—not only pass/fail
- Facility-owned acceptance criteria or baseline
- Exceptions, corrective actions, and retest triggers
Regulatory context: 21 CFR Part 117 is risk-based. It does not prescribe a universal annual mag-trap test, a universal gauss threshold, or a universal third-party provider requirement. The facility remains responsible for its hazard analysis, control design, procedures, acceptance criteria, frequency, corrective actions, and records.
