Dust measurement guideline 2025: common rules for measuring dust on construction sites

Illustration: an unfinished data hall with a row of empty black equipment racks with their doors open, a partly installed white raised floor and cable trays on the ceiling. On the right there is a plastic containment wall with an air purifier beside it, and a beam of light shows the dust in the air.

A clean data hall starts on the construction site: measuring dust when building a data centre

Illustration: the outside corner of a light three-storey apartment building in winter. The wind sweeps snow around the corner, and a drift has built up against the wall on the sheltered side.
