GSO ASTM D7143:2021 Scope
1.1 This 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:
1.1.1 To 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.
1.1.2 To promote the development of products with lower
VOC emissions.
1.2 This 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.
1.3 In 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.
1.4 This 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.
1.5 Air 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.
