This Info Hour is intended for members of the Weights and Measures community who are responsible for regulating\, designing\, or evaluating weighing instruments.


Section 2.20.\, S.1.2.1 . Digital Indicating Scales\, Units in NIST Handbook 44 needs clari fication to ensure scales are designed to properly determine an accurate net weight. S.1.2.1.\, specific ally the second paragraph\, which includes an example\, can be interpreted as requiring mathematical agreement between the gro ss\, net\, and tare weight < /span>values when a tare mechanism is in operation. However\, this mathematical agreement can result in an inaccurate net weight. Current testing and evaluation procedures do not adequately allow this issue to be easily identified.
