Introduction

JJF 1071-2010 "Rules for the Preparation of National Metrology Calibration Specifications", JJF 1001-2011 "General Terms of Measurement and 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. ---JJF 1074-2001. 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.

2 reference files

This specification refers to the following documents. JJG2094-2010 Density measuring instrument JJF 1229-2009 Terms and definitions of mass density measurement OIMLR22 Determination of Alcohol Concentration (International Alcohol Table) (Traceabilityandcomputerizationof Alcoholometrictables) OIMLR44 Alcohol meter and alcohol density meter and thermometer for alcohol concentration measurement (Alcoholometers Andalcoholhydrometersandthermometersforuseinalcoholometry) For dated references, only dated versions apply to this specification; undated quotations The latest version (including all amendments) applies to this specification.

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.
