ISO 14644-1 Class 8
Data Center Cleaning & Decontamination
Cleanroom-grade particulate control for live data halls — without touching uptime.
Overview
Particulate is the silent failure mode of a data hall. Construction dust, zinc whiskers shed from raised-floor tiles, and HVAC-borne contamination drive thermal inefficiency, ESD events, and hardware failures that never show up on a one-line diagram. We clean live, under-load environments to ISO 14644-1 Class 8 limits — with HEPA/ULPA filtration, static-dissipative methods, and particle-count verification before and after.
What's included
Inside our cleaning scope
Data hall & rack cleaning
Surface decontamination of cabinets, racks, and the white-space floor in live, under-load conditions.
- →ESD-safe, static-dissipative cleaning agents
- →Top-of-cabinet, rail, and PDU detailing
- →No interruption to running equipment
Subfloor & plenum cleaning
The raised-floor plenum is the supply-air path — contamination there is pushed straight into every server intake.
- →Cable-tray and underfloor debris extraction
- →Concrete slab encapsulation where specified
- →Airflow restored, hotspots reduced
Zinc-whisker remediation
Conductive zinc whiskers shed from electroplated floor tiles and structural steel cause intermittent shorts and ESD failures that are nearly impossible to diagnose.
- →Identification and microscopy confirmation
- →Containment, removal, and source abatement
- →Tile replacement / re-coating recommendations
Post-construction & pre-commissioning clean
The final clean that takes a freshly built data hall from drywall dust to commissioning-ready — on the GC's schedule.
- →Construction debris and fine-dust removal
- →Coordinated with commissioning agents
- →Particle-count sign-off for handover
How we work
A documented process, every time.
Baseline
Airborne particle counts and surface sampling to document the starting condition and target ISO class.
Containment
Zone the work area, protect live racks, and run filtered negative-air where contamination is mobile.
Decontaminate
Top-down clean — ceiling plenum, racks and cabinets, floor surface, then subfloor — with HEPA/ULPA vacuums and ESD-safe agents.
Verify
Re-test particle counts against ISO 14644-1 Class 8 and deliver a signed before/after report for your records.
FAQ
Cleaning, answered
The questions buyers — and their auditors — actually ask.
What is ISO 14644-1 Class 8 cleaning for a data center?
ISO 14644-1:2022 Class 8 is a cleanroom air-cleanliness classification that limits airborne particles to 3,520,000 particles ≥0.5 µm per cubic meter. For data centers it is the practical target for white-space and data-hall cleaning: clean enough to protect hardware and airflow without the cost of a true cleanroom. We clean to that limit and verify with calibrated particle counters before and after.
Is 'ISO 8' the same as 'Class 8'?
Yes. 'ISO 8' is shorthand for ISO 14644-1 Class 8. An older U.S. standard (Federal Standard 209E) used 'Class 100,000', which corresponds to roughly the same cleanliness level. Buyers use the terms interchangeably.
Can you clean a live data hall without downtime?
Yes. Our standard mode is cleaning live, under-load environments. We zone and contain the work area, use ESD-safe tools and static-dissipative agents, and never interrupt running equipment. No maintenance window is required for routine decontamination.
What are zinc whiskers and why do they matter?
Zinc whiskers are microscopic conductive filaments that grow from the electroplated zinc on raised-floor tiles, struts, and structural steel. When disturbed by airflow or maintenance they become airborne, settle into equipment, and cause intermittent shorts, ESD events, and unexplained hardware failures. Remediation requires containment, HEPA removal, and abating the source — not just a surface wipe-down.
Do you provide documentation for our compliance records?
Every engagement includes a signed before/after particle-count report mapped to ISO 14644-1 Class 8, plus a scope-of-work record suitable for audit, insurance, and approved-vendor compliance.
