Introduction

JJF1001-2011 "General Measurement Terms and Definitions", JJF1007-2007 "Temperature Measurement Terms and Definitions "Yi" and "JJF1002-2010" Rules for the Compilation of National Metrology Verification Regulations "together constitute the supporting work for the revision of this regulation Basic norms. This regulation refers to OIMLR7.1979 (E) "(Mercury glass with the highest retention point structure) thermometer" Revise the relevant content such as gauge type, scale, maximum allowable error, etc. This regulation replaces the verification procedure of JJG 111-2003 "Glass Thermometer", and JJG 111-2003 "Glass Body" Compared with the Thermometer, the main technical changes except for editorial changes are as follows. --- Add the second-class standard platinum resistance thermometer as an optional standard; --- Improved the technical requirements of the constant temperature bath; --- Added check in use; --- Deleted some verification items; --- Modified the method of judging the result of indication error; --- Added a description of the method for simultaneously verifying multi-branch thermometers. Previous releases of this regulation. --- JJG 111-2019; --- JJG 111-2003; --- JJG 111-1989. Verification Regulation of Glass Thermometer

1 Scope

This verification procedure is applicable to the measurement range of 30.0 ℃ ~ 43.0 ℃, with the highest retention point structure, the temperature sensitive medium is Liquid glass thermometer (hereinafter referred to as thermometer) for the first verification and inspection in use.

2 Reference documents

This regulation refers to the following documents. JJG 160 standard platinum resistance thermometer JJG 881 standard thermometer JJF1007-2007 Temperature measurement terms and definitions GB 1588 glass thermometer For dated references, only the dated versions are applicable to this Regulation; for those without dates The latest version (including all amendments) is applicable to this regulation.

3 Terminology

The following terms and definitions defined in JJF1007-2007 "Terms and Definitions of Temperature Measurement Terms" and the following apply to this procedure. 3.1 Scale A combination of a set of lines, numbers, and unit of measurement symbols (° C) on the thermometer, used to indicate temperature, also known as Scale. 3.2 Scale line The line engraved on the glass rod or scale plate to indicate the temperature value is also called the scale line. 3.3 scale value The number printed on the glass rod or scale plate to indicate the temperature value is also called the scale value. 3.4 scaleplate Straight, colored (e.g. milky white) thin, engraved scale lines, scale values and other symbols in the internal standard thermometer Piece, also called scale plate. 3.5 Interrupt liquidcolumngap The liquid column of the thermometer is disconnected above the retention point structure. 3.6 Self-liquid liquid column receding solely The phenomenon that the temperature-sensing liquid column of the thermometer retracts toward the temperature-sensing bubble on the part above the retention point structure. 3.7 Liquidcolumnrecedingdifficultly Under a certain external force, it is difficult for the temperature sensing liquid column of the thermometer to retract from above the minimum temperature scale line to the minimum temperature scale The phenomenon below the degree line.
