Cleanroom Validation

Recurring cleanroom validation, aligned with ISO 14644

Cleanrooms drift out of specification quietly — a filter here, a pressure differential there. Our cleanroom validation service catches that drift on a documented schedule, so your controlled environment stays inside its classification year-round.

Cleanroom validation is the recurring, documented process of confirming a controlled environment continues to meet its required classification over time — as opposed to a single one-off test. Vanavil Calibrations provides cleanroom validation services aligned with ISO 14644 classification principles, with full test-parameter documentation on every visit.

Validation vs. a Single Test

A schedule, not a snapshot

A single clean room test tells you how a space performs on the day it's measured. Validation is the ongoing discipline around that — a defined schedule of requalification, consistent test procedures, and a documented history that shows a facility's controlled environment has been continuously in specification, not just compliant on inspection day.

This is the distinction auditors look for: not just "was it tested," but "is there a validation programme."

Validation Process

Baseline Assessment

We confirm the room's classification and define the validation scope and schedule.

Scheduled Testing

Testing runs against ISO IEC 17025:2017 procedures at the agreed interval.

Documented Reports

Every cycle produces a dated, parameter-by-parameter report for your validation file.

Requalification Advice

We flag when a change in layout or equipment means the room needs requalifying sooner.

FAQ

What standard does cleanroom validation follow?

We work in line with ISO 14644 classification principles for cleanrooms and controlled environments, alongside ISO/IEC 17025:2017-compliant test procedures.

How is validation different from a one-off test?

Validation is the recurring, documented process of confirming a cleanroom continues to meet its classification over time, not a single measurement. It typically includes scheduled requalification — see Clean Room Qualification.

Do you validate cleanrooms in both pharma and hospital settings?

Yes. We validate cleanrooms and controlled environments across hospitals, pharmaceutical facilities, laboratories and industrial sites.
