VDI 4302 BLATT 1
Sensory testing of indoor air and determination of odour emissions from building products - Fundamentals
|Publication Date:||1 April 2015|
|ICS Code (Ambient atmospheres):||13.040.20|
The standard deals with the principles and methods for the sensory testing and assessment by panel members of odours in indoor air and of interior building products.
Methods and criteria are presented for the performance of tests by means of which odour emissions from interior building products and odour impact in interiors are to be judged in terms of acceptability, odour intensity, hedonic tone and odour quality. In addition to the general conditions necessary for tests, the requirements to be satisfied by panel members are also defined.
DIN ISO 16000-30 describes the performance of sensory testing of indoor air. The determination of odour emissions from interior building products with an emission test chamber is defined in DIN ISO 16000-28.
There are various possible reasons for sensory testing of indoor air and interior building products. The goals of an expert and well-founded assessment of odours in interiors and from interior building products can be not only to search for the causes of odours considered unpleasant or annoying, but also to determine whether the rooms affected can be used and whether the perceived odour nuisance is acceptable.
According to the Model Building Regulations (MBO), indoor rooms are rooms that are intended or suitable for not only temporary human occupancy. In the series of standards VDI 4300, the following rooms are classified as indoor rooms according to the definition of the Council of Experts on Environmental Issues :
• dwellings with living rooms, bedrooms, handicraft rooms, sports and cellar rooms, kitchens and bathrooms
• workrooms and workplaces in buildings that are not covered by the scope of the Hazardous Substances Ordinance (GefStoffV) in terms of hazardous substances, e.g. office rooms interiors in public buildings, e.g. hospitals, schools, child-minding premises, gymnasiums, libraries, restaurants, pubs, theatres, cinemas and other public events rooms
• cabins of motor vehicles and public transport
The odour tests presented in this standard are particularly suitable for office and administration buildings, meeting places, public buildings, residential buildings and other general indoor rooms in which the emphasis is on the comfort and well-being of the room's users. Excluded from this are vehicle and aeroplane interiors and rooms in which odours are inevitable because of production processes, e.g. canteens, bakeries, etc.
This standard does not cover the execution of the chemico-physical measurement of odorants.
The subsequent parts of series of standards VDI 4302 only apply in connection with this standard.
