Measured, not guessed

Particle Testing & Site Assessment

Most hardware makers ask for a data hall at ISO 14644-1 Class 8 or cleaner. A particle count tells you where your room stands before cleaning, and proves the result afterwards.

Airborne particle counts with a laser particle counter, reported against ISO 14644-1 cleanliness classes, plus a walk-through of surfaces, subfloor and overhead areas.

Airborne particle counts

Measured with a laser particle counter at defined sample points across the room.

Counts in size channels from 0.3 µm to 5.0 µm (0.3, 0.5, 1.0 and 5.0 µm)
Sample locations set out per ISO 14644-1 for the room’s floor area
Results reported as an ISO 14644-1 class, with Class 8 as the usual data-center target
Counts repeated after cleaning so the improvement is on paper

Site assessment

A look at where contamination comes from, not just how much there is.

Visual inspection of equipment, floors, overhead surfaces and the subfloor
Notes on filtration, door seals, tacky mats and other entry points for dust
Zinc whisker check on pedestals and tile undersides where accessible
A written report with findings, photos where allowed, and a recommended cleaning plan

How big is a micron?

One micron (µm) is a thousandth of a millimetre. The particles that damage equipment are far below what the eye can see — which is why we measure them.

Beach sand100–2,000 µm

Table salt~100 µm

Human hair50–100 µm

Limit of visibility~40 µm

Pollen10–100 µm

Fine dust (PM10)≤10 µm

Red blood cell~7.5 µm

Bacteria1–5 µm

Smoke0.01–1 µm

Virus~0.1 µm

Typical sizes; size and scale are approximate. Logarithmic scale — each step is ten times larger.

The exact scope is agreed with your facility team before work starts. Anything outside it — or anything your site does not approve — is left alone. How we work around live equipment.
