Cleanroom & Controlled Environment Solutions
Measurement technologies for airborne particle classification, continuous monitoring, installed-filter integrity, recovery, airflow visualisation and specialised controlled environments.
Controlled-environment performance requirements
Define whether the requirement is classification, ongoing monitoring, installed-filter integrity, recovery or airflow behaviour. The method, governing reference and measurement architecture differ for each activity.
Establishing performance at a defined condition
A measurement executed against a stated occupancy state, a defined sampling plan, defined sample volumes and selected particle-size thresholds. The result is evidence of performance at that condition, recorded together with the conditions that produced it.
Providing evidence that performance is maintained
A monitoring plan defining fixed or periodic measurement points, alarm limits, response and record retention from a risk assessment of intended use. A fixed sensor does not classify a room, and a portable classification counter is not by itself a monitoring system.
Which activities apply — and in which occupancy state, at which locations and against which acceptance criteria — is set by the applicable specification, the facility design and the governing test method for the project. No single measurement is universally mandatory for every controlled environment.

Semiconductor contamination-control priorities
Semiconductor facilities can require extremely low airborne-particle concentrations, with measurement strategy determined by process sensitivity, selected cleanliness class, particle-size threshold and facility contamination-control requirements. The measurement route follows the requirement of the specific area rather than a single facility-wide assumption.
- Ultra-clean classificationWhere the requirement is stated at 0.1 µm, the instrument itself must resolve that size.
- High-flow verificationHigher sample flow shortens sampling time at low concentrations and improves counting statistics.
- Critical-area monitoringFixed sensors at risk-assessed locations feeding trend, alarm and retained evidence.
- Equipment suitabilityAssessment of tools introduced into the cleanroom with respect to airborne-particle concentration.
Pharmaceutical qualification and monitoring priorities
Sterile-manufacturing environments combine cleanroom classification with facility-specific qualification, requalification and operational environmental-monitoring requirements, inside a documented contamination control strategy.
Measurement evidence is generated under an approved protocol; qualification review and acceptance remain within the facility quality system, contamination control strategy and authorised testing responsibility.
- ClassificationAirborne-particle classification of the graded area.
- Final-filter integrityIntegrity test of the installed final filters.
- RecoveryRecovery testing for appropriate non-unidirectional environments.
- Environmental monitoringOngoing evidence of continued performance between qualification events.
Healthcare and specialised environment verification
Spatially confined clean-air enclosures and healthcare environments are verified against their own device- and facility-specific standards, which are frequently regional. They are not covered by cleanroom classification alone.
Healthcare ventilation verification references such as DIN 1946-4 and SWKI VA105-01 are regional or project-specific. They apply where a project, customer specification or local regulation calls for them, and are not automatically Indian statutory requirements.
Standards and measurement applicability
Each reference governs a different measurement or assurance activity. Select it from the required evidence, the test object and the applicable project or regulatory context.
