Full Description

1.1This practice is intended for determining volatile organic compound (VOC) emissions from materials and products using emission cells. It can be applied in principle to most construction materials and many products used indoors. Objectives include:

1.1.1To provide manufacturers, builders, and end users with emission data useful for evaluating the impact of building products, new or old, on indoor air concentrations in a model room.

1.1.2To promote the development of products with lower VOC emissions.

1.2This practice is for identifying emitted VOCs and for determining the area specific emission rate of VOCs from newly produced building products under defined climate conditions. The method can also be applied to aged products.

1.3In accordance with the definition of an emission cell, it is also possible to perform nondestructive emission measurements on building products on-site in buildings. However, the procedure for such measurements is not described in this practice.

1.4This practice describes the design, construction, performance evaluation and use of emission cells for VOC emission testing. Sampling, transport and storage of materials to be tested, and preparation of test specimens are also described.

1.5Air sampling and analytical methods for the determination of VOCs are described in Practice D6196. Alternative sampling and analytical approaches for formaldehyde and other carbonyls are described in Test Method D5197.

Note 1:All volatile (vapor-phase) carbonyls except formaldehyde can be analyzed by either Practice D6196 or by Test Method D5197.

Note 2:Direct-reading instruments can also be applied for specific objectives.

Note 3:Some volatile inorganic compounds can, in principle, also be analyzed (for example, ammonia).

1.6An example of an emission cell is described in Appendix X2 of this practice.

1.7The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.8This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
