3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Weight weight
Has a shape, size, material, surface conditions, the nominal value, the quality of the physical properties of density, magnetic properties and maximum permissible error, etc. and metrological characteristics
Material measure.
Note. For a weight, which can be individually reproduced a fixed weight value. For the weight set, it can not only be used individually alone, it can also be different single
A weight used in combination to reproduce a number of different sizes of a set of quality values.
3.2
Translation quality conventionalmass
Translation quality value theconventionalvalueofmass
An object at the agreed temperature and density of the air agreement, and agreed to a standard density reaches equilibrium quality standard device.
NOTE. Convention temperature is 20 ℃, the agreed air density is 1.2kg/m3, the standard convention density of 8000kg/m3. Translation quality and value mc vacuum
The mass value m relationship see equation (1).
mc = m (Vc-V) ρ0 =
(1-
ρ0
0.99985m

Where.
ρ --- weight density;
ρ0 --- air density;
m --- weight quality value vacuum;
mc --- weight conversion quality value;
V --- weight vacuum volume;
Vc --- weights agreed volume.
