    Mass
    RCS Method has been written with reference only to guidelines specified in ASTM E898-00, and E319-03. Portions of NIST Handbook 44-04 have also been consulted for applicable requirements. NBS Circular 547 & OIML R-111 Tolerances observed.  Method covers the determination of characteristics of top-loading, direct reading laboratory scales and balances. Laboratory scales of the top-loading type may have capacities from a few grams up to several kilograms.
