Before you accept the room, make sure damaging construction dust is out. Cleaned and certified to ISO 14644-1:2022 Class 8, plus all accessible surfaces free from dust.
After construction or refurbishment of your data centre, data room, server room, data hall or comms room, the space will be contaminated with submicron particles caused by construction activities. Prior to accepting the room, you should ensure your contractor has it cleaned.
The current accepted best-practice specification is “Room to be cleaned to ISO 14644-1 Class 8 plus all accessible surfaces free from dust.” This ensures damaging dust is removed from the air and from all accessible surfaces so it can’t be re-suspended by human activities.
“One has to remember that 1000 µm = 1 mm. Therefore at 0.5 µm, 2,000 particles will pass through a hole 1 mm in size, line abreast.” — Stephen Yates, MD
Class 8 applies limits to particulate sizes at 0.5 µm, 1.0 µm and 5.0 µm respectively — with maximums of 3,520,000 · 832,000 · 29,300 per m³.
The problem
After construction or refurbishment, your data centre is contaminated with submicron particles — plaster, cement dust and abrasive silica down to 0.3 µm.
Why it's hard
At these sizes, gravity is the last force acting on the particles. Static, air movement, Van der Waals and Brownian motion keep them airborne and moving.
The remedy
Full surface clean plus HEPA air scrubbing, validated to ISO 14644-1:2022 Class 8 with a Solair 5100+ counter. Certificates issued on completion.
Often called a ‘5 micron clean’ or ‘clinical clean’. Includes air scrubbing, surface cleaning and full ISO 14644-3 validation.
Please note
We only offer this as a post-construction clean. If the site is still an active construction site requiring a builders clean, we recommend partners we have trained in ISO 14644-1 Class 8 cleaning. Ask us for a referral.
