Standard Practice for Collection of Floor Dust for Chemical Analysis

Importancia y uso:

5.1 This practice may be used to collect dust from carpeted or bare floor surfaces for gravimetric or chemical analysis. The collected sample is substantially unmodified by the sampling procedure.

5.2 This practice provides for a reproducible dust removal rate from level loop and plush carpets, as well as bare floors. It has the ability to achieve relatively constant removal efficiency at different loadings of floor dust.

5.3 This practice also provides for the efficient capture of semivolatile organic chemicals associated with the dust. The test system can be fitted with special canisters downstream of the cyclone for the capture of specific semivolatile organic chemicals that may volatilize from the dust particles during collection.

5.4 This practice does not describe procedures for evaluation of the safety of floor surfaces or the potential human exposure to floor dust. It is the user's responsibility to evaluate the data collected by this practice and make such determinations in the light of other available information.

5.5 This practice provides per-event dust chemical concentration and chemical loading. Advantages and trade-offs of different sampling approaches have been discussed (7).

5.6 This practice uses a removable, cleanable dropout jar that facilitates per-event sampling. Other per-event vacuum attachments are commercially available. These are not directly comparable with composite sampling done using whole vacuum cleaner bags.
