This part of ISO 16000 specifies a laboratory test method to measure the odour emission from newly produced building products using a sensory odour panel. The odour characteristics addressed in this standard are the acceptability and the perceived intensity. It depends on the measurement task whether the acceptability, perceived intensity or hedonic or a combination or both characteristics shall be determined. The method can also be used for building furnishings (i.e. wall and floor coverings, furniture, paints, etc.) and is also applicable to aged products. The determination of odour acceptability, intensity and hedonic tone, and intensity of emissions from building products using test chambers has objectives such as: - to provide manufacturers, builders, and end users with data useful for the evaluation of the odour impact of building products on the indoor air quality; - to promote the development of improved products.
