Such scales shall meet the applicable requirements contained in National Institute of Standards and Technology (NIST) Handbook 44, "Specifications, Tolerances, and Other Technical Requirements for Weighing and Measuring Devices," 1999 Edition, November 1988, which is incorporated by reference. Scale tolerances have been established by the NIST and are contained in their published handbook - Handbook 44. The acceptance tolerance values apply only to digital type scales regardless of the increment of calibration. These tolerance values do not apply to dial-type scales which must be adjusted to reflect the actual weight of the test weight. Handbook 44 was first published in 1949, having been preceded by similar handbooks of various designations and in several forms, beginning in 1918. Handbook 44 is published in its entirety each year following the Annual Meeting of the National Conference on Weights and Measures (NCWM). The Committee on Specifications and Tolerances of the NCWM NIST Handbook 44-2003, Section 5.52 (Gaithersburg, MD: National Institute of The tolerances shown in other sections of this book for plumb and level for individual construction materials and assemblies are often more or less accurate than those shown in this section.
