Overview
Semi-volatile organic compounds (SVOCs) such as phthalic esters are found in many construction materials. If emitted into the indoor environment they adhere to many surfaces and can become a persistent indoor air contaminant. Therefore, they represent a long-lasting health risk for the residents. This part of ISO 16000 specifies a test method for determination of the area-specific emission rate of semivolatile organic compounds (SVOCs) from newly produced building products or furnishings under defined climate conditions using a micro-chamber. The principle of the test is to determine the area specific emission rates of SVOCs emitted from the surface of a product test specimen. 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, and their combinations. 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 standardized sampling, storage of samples and preparation of test specimens aims, for example, 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; - promote the development of improved products. Sampling, transport and storage of materials to be tested, and preparation of test specimens are specified in ISO 16000-11. Air sampling and analytical methods for the determination of SVOCs are specified in ISO 16000-6 and ISO 16017-1. An application example of a micro-chamber is described in Annex B of ISO 16000-25. The International Standard has been prepared by ISO/TC 146/SC 6 "Indoor air", the chairmanship and secretariat of which is held by DIN, in Working Group 12 "Semi-VOCs in building products". The responsible German committee is NA 134-04-04-01-06 AK "Flüchtige organische Verbindungen (VOC)" ("Volatile organic compounds (VOCs)").
