Certified Data Center Cleaning — ISO 14644-1 & ISO 14644-13

DustTrace™ Surface Particle Scanner

Not only looks clean — measured clean.

A data center can look spotless and still carry submicron dust that the eye can’t see. DustTrace™ uses a controlled pulse of air pressure to lift settled dust from the surface and count the released particles. Our partners use it on site to measure settled dust before and after every cleaning, so the result is proven by numbers — and certified in a CleanCertify™ report.

Definition · Settled dust

Settled dust is airborne dust that has dropped out of suspension and rests loosely on server rack top covers, PCB circuit boards, cable trays or floor tiles. Because it is only loosely held, it easily becomes airborne again through air movement, foot traffic or work in the data hall.

ISO 14644-1

Air cleanliness

Airborne particle levels in the data hall, classified to ISO 14644-1.

ISO 14644-13

Cleaning methods & assessment

Settled dust on floors, racks and equipment measured before and after cleaning, to assess cleaning effectiveness per ISO 14644-13.

Why Surfaces Matter

Class 8 air does not mean a clean data center.

A data hall can meet the ISO 14644-1 Class 8 air requirement on the day it is tested and still be contaminated. Air counts are a snapshot. Settled dust resting on floors, subfloors, cable trays and equipment is not counted — until it becomes airborne.

This is a growing problem in new hyperscale and AI data centers. Construction dust settles into every surface before go-live, and dense GPU racks move enormous volumes of air through the hall. Clean air can turn contaminated in moments when surfaces are not clean too.

That is why DustTrace™ measures settled dust before and after cleaning, and why every CleanCertify™ report references both ISO 14644-1 and ISO 14644-13.

What puts settled dust back into the air

01
Air currents
High-volume cooling airflow and pressure changes lift loose dust from floors, subfloors and overhead surfaces.
02
Fire-suppression gas discharge
A gas dump, even without a fire, releases a sudden blast of air that stirs up settled dust across the whole room.
03
Renovation and installation work
Construction, cabling and equipment moves both create new dust and disturb dust already present.
04
Improper cleaning
Cleaning with the wrong protocols and equipment can spread contamination and make it airborne rather than remove it.

How Certification Works

Our partners clean. We certify the result.

We work with cleaning partners worldwide. They measure with DustTrace™, and we independently certify the result as a CleanCertify™ report.

Measured before and after cleaning

A Technology Care partner measures settled dust with DustTrace™, cleans the data center, then measures again.

Encrypted data analysed in Switzerland

The measurement data is encrypted and transferred to our laboratory in Switzerland, where it is analysed.

CleanCertify™ report issued

You receive a certified CleanCertify™ report referencing ISO 14644-1 and ISO 14644-13.
