The electromagnetic lock engages, preventing interruption during the critical test phases.

Dust circulation commences as the blowing system disperses talcum powder throughout the chamber volume. The mesh sieve filters agglomerated particles, ensuring uniform particle size distribution. Visual monitoring through the observation window confirms adequate dust density and circulation patterns.

Vacuum application creates negative pressure within the chamber, drawing dust toward specimen openings and potential ingress points. The pressure gauge displays real-time vacuum levels, with the programmable controller maintaining setpoint values throughout the test duration.

Test Phase	Duration	Activity	Monitoring Parameters
Conditioning	30-60 minutes	Environmental stabilization	Temperature, humidity
Dust Circulation	2-8 hours (variable)	Active particle dispersion	Dust density, airflow
Vacuum Application	Continuous during circulation	Negative pressure maintenance	Vacuum level, specimen response
Settling Period	1-2 hours	Passive dust deposition	Particle settlement patterns
Post-Test Stabilization	30 minutes	Return to ambient conditions	Temperature normalization

Networked data logging captures all environmental parameters at regular intervals, creating a comprehensive test record. Operators can remotely monitor test progression without disturbing chamber conditions, particularly valuable for extended 8-hour test sequences.

The settling period following active circulation allows airborne particles to deposit naturally, revealing whether openings captured dust during circulation or if effective sealing prevented ingress. This phase often distinguishes borderline protection levels.

Post-Test Evaluation and Reporting

Upon test completion, the electromagnetic lock releases and the chamber door opens carefully to avoid disturbing deposited dust. Technicians photograph the specimen condition before any handling occurs, documenting external dust accumulation patterns.

Specimen disassembly proceeds methodically, with inspectors examining each internal compartment for dust presence. IP5X testing permits limited dust deposits that don't interfere with equipment operation or safety, requiring judgment regarding harmful versus acceptable quantities.

IP6X evaluation demands absolute absence of internal dust, verified through visual inspection under magnification and sometimes weight measurement comparing pre-test and post-test mass. Even microscopic particle counts can invalidate dust-tight claims.
