EVS-EN 13098:2001

This European Standard provides guidelines for the assessment of workplace exposure to airborne micro-organisms including the determination of total number and culturable number of micro-organisms in the workplace atmosphere. The standard also provides methods for measurement of airborne endotoxin in the work environment. The standard does not apply to  viruses, specific pathogenic micro-organisms and toxins other than endotoxin, although some of the measurement principles may be the same.
