Short description
This measurement technique is a set of instructions for determine the odour impact in an assessment area. The odour load is measured in this case by qualified (EN 13725) assessors or testers, who assess the ambient air for odour with different qualities at previously defined locations within certain measurement cycles. The grid measurement is a statistical survey method in which over a certain period, e. g. six months, assessors record detected odour impressions and qualities at grid intersection points in the assessment area with a certain methodology. The results can be used for calculating the odour impact characteristic for the assessment squares in the assessment area.
