The concentration of mould inside the negative pressure enclosure determined from the air clearance testing should be qualitatively and quantitatively similar to that of outside air or a background sample obtained from an uncontaminated area of the building before the enclosure is removed. 1, record 2, English, - air%20clearance%20testing
