Cleanroom particle-count verification (ISO 14644-1 Class 8)

When you need this form

Data hall and technical space cleaning is verified, not assumed. This form captures the particle counts taken after a clean, the instrument used, sample locations and whether the room met the cleanliness class written into the contract. It also carries the onboarding and access evidence colocation operators demand before a cleaner sets foot on a raised floor.

Hyperscale and colocation clients audit hard, and hardware warranties can hinge on documented environmental conditions. Numbers typed into a spreadsheet after the fact convince nobody. Readings captured on the floor, with the meter photographed, the sample point named and the technician signed, give the operator something they can hand to their own auditor without rework.

What good looks like

• Sample points named and mapped, not "random spots in the hall".
• Counts recorded per channel size, with pass or fail against the target class.
• Instrument make, serial and last calibration date captured with the reading.
• Photo of the meter display at each sample point.
• Technician and client representative both signing the verification result.
