Precision—The precision of this test method for the
determination of Total Moisture in Coal. The repeatability and
reproducibility limits given in Table 1 apply only to coals
without free (surface) moisture in the gross sample before
preparation of No. 8 (2.36-mm) sieve-size subsamples. When
duplicate No. 8 (2.36-mm) sieve-size subsamples are air dried,
reduced to No. 60 (250-μm) sieve size, and their residual
moistures determined, the following repeatability and reproducibility
limits apply to the resulting total moisture values.
