The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 16000-9 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 264, Air quality, in collaboration with Technical Committee ISO/TC 146, Air quality, Subcommittee SC 6, Indoor air, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

The method can in principle be used for most building products used indoors.

The method can also, in principle, be applied to aged products. The emission data obtained can be used to calculate concentrations in a model room. This part of ISO 16000 applies to various emission test chambers used for determination of the emission of volatile organic compounds from building products or furnishing. 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 VOCs are described in ISO 16000-6 and ISO 16017-1 11. A general description of an emission test chamber is given in Annex C of this part of ISO 16000. For the determination of formaldehyde emissions from wood-based panels, refer to EN 717-1:2004 12. However, ISO 16000-9 is also applicable to wood-based panels and other building products, in order to determine the emission rate of formaldehyde. The measurement procedure for formaldehyde is described in ISO 16000-3 1. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

NOTE 1 For quantification of the identified compounds, their individual response is used. The areas of the unidentified peaks are converted on molecular mass basis to concentrations using the toluene response factor 2. NOTE 2 Due to practical reasons to be taken into account for test chambers, this definition differs slightly from that defined in ISO 16000-6:2004. In ISO 16000-6, TVOC are related to the sampling medium Tenax TA®1) on which the TVOC are adsorbed. 3.15 volatile organic compound VOC organic compound that is emitted from the test specimen and all those detected in the chamber outlet air NOTE 1 Due to practical reasons to be taken into account for test chambers, this definition differs from that defined in ISO 16000-6:2004. In ISO 16000-6, the definition is based on the boiling point range (50 °C to 100 °C) t
