BS ISO 16000-28:2020 pdf free.Indoor air.Determination of odour emissions from building products using test chambers.
BS ISO 16000-28 1 Scope This document specifies a laboratory test method using test chambers defined in ISO 16000-9 and further specified in EN 16516 and evaluation procedures for the determination of odours emitted from building products and materials.Sampling, transport and storage of materials under test, as well as preparation of test specimens are described in ISO 16000-11 and further specified in EN 16516.2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

EN 16516, Construction products: Assessment of release of dangerous substances一Determination of emissions into indoor air.The odour emission from building products and materials is measured using a sensory odour panel. The
odour determination may be performed in parallel to chemical emission measurements in accordance with ISO 16000-9 and further specified in EN 16516. The odour characteristics addressed in this part of ISO 16000 are the acceptability, the perceived intensity and the hedonic tone. Depending on the measurement task, these odour characteristics or a combination of those can be determined.A facility designed and operated to determine odours emitted from building products and materials consists of an emission test chamber containing the test specimen. The emission test chamber shall contain a clean air generation and humidification system, an air mixing system and monitoring and control systems to ensure that the test is performed to indicated conditions in accordance with ISO 16000-9 and further specified in EN 16516.The standard procedure for odour assessment is carried out by using sample containers (see 6.3.3).Alternatively, direct assessment from the outlet of the emission test chamber is possible if sufficient air flow is assured (see 6.3.1]. In this case the outlet shall be fitted with a funnel.BS ISO 16000-28 pdf download.
