Semi volatile organic compounds (SVOCs) such as phthalic esters are found in many construction materials. If emitted to the indoor environment they stick to many surfaces and can become a persistent indoor air contaminant, posing a potential long term health risk to building occupants. This part of ISO 16000 specifies a test method for determination of the area specific emission rate of semi volatile organic compounds (SVOCs) from newly produced building products or furnishings under defined climate conditions using a micro-chamber. The method can in principle also be applied to aged products. This measurement method is applicable to products/materials such as board materials, wallpapers, flooring materials, insulation materials, adhesives, paints, etc and products which are combinations of the above. This method can, in principle, be used for most building products used indoors. The determination of semi volatile organic compounds (SVOCs) emitted from building products using micro-chambers in conjunction with standardised sampling, storage of samples and preparation of test specimens has objectives such as: - to provide manufacturers, builders, and end users with emission data useful for the evaluation of the impact of building products on the indoor air quality; - to promote the development of improved products. Sampling, transport and storage of materials to be tested, and preparation of test specimens are described in ISO 16000-11. Air sampling and analytical methods for the determination of SVOCs are described in ISO 16000-6 and ISO 16017-1. An example of a micro-chamber is described in Annex B of this part of ISO 16000-26.
