NOTE: All samples (cassettes and wipes) will be preweighed by the laboratory or supplier prior to sample collection. After sample collection and upon receipt of the samples by the loborctory. the iloborotory will weigh the sample wipe or cassette prior to performing the analysis. This may change depending upon the qvailoblllty of preweighed materials, Moy celled samples for total dust.
