The Definitions together constitute the basic series of specifications that support the revision of this Code.
This specification is compared with JJF 1074-2001 "Alcohol Density - Concentration Measurement Table", except for editorial modifications, the main
The technical changes are as follows.
--- Added introduction;
--- Revised and unified the definition of mass percent concentration and volume percent concentration;
--- Revised the description of the alcohol density measuring instrument;
--- Added (0~40) °C pure water density meter in the appendix;
--- Add four commonly used alcohol density-concentration tables.
The previous versions of this specification were released as follows.

Alcohol density-concentration measurement table
1 Scope of application
This specification applies to alcohol meters and density bottles in the range of (-20~ 40) °C (ITS-90), measuring wine
The solution density of the fine solution - the concentration of the table is calculated.

3 terms and units of measure
3.1 mass percent concentration masspercentageconcentration
The percentage of the mass of the solute m' in the solution to the mass m of the solution, also known as the mass fraction, ie.
p=
m'
m ×100%
(1)
p is a dimensionless quantity and is represented by "p. fractional" or "p. %".
3.2 volume percent concentration volumepercentageconcentration
The percentage of the solute volume V' contained in the solution to the volume V of the solution, also known as the volume fraction, ie.
q=
V'
V×100%
(2)
q is a dimensionless quantity, expressed as "q. fractional" or "q.%".
4 measuring instruments
Measuring alcohol density - concentration can be used in the following types of instruments.
4.1 Benchtop Density Meter
An instrument that measures the density of a liquid using the relationship of vibration frequency as a function of density, and is typically used in the laboratory.
4.2 Alcohol meter
A glass float meter for determining the volume percent concentration or mass percent concentration of an alcohol solution. The general standard temperature is
At 20 ° C, the reading method is the lower edge reading, indicating q. %, ie volume percent concentration.
