Verification of working capillary viscometer1 ScopeThis procedure applies to Uzbekot type (referred to as Wu's), flat open Wei Qi type (referred to as Ping's), Finske type (referred to as (Hereinafter referred to as "free flow") working capillary viscometer (hereinafter referred to as viscometer) The first test, follow-up test and the use of inspection.2 reference fileJJG 2016 Viscometer Measuring Instrument For dated references, only the dated edition applies to this rule; references that are not dated , The latest version (including all amendments) applies to this procedure.3 OverviewViscometer is mainly used for liquid sample kinematic viscosity measurement. Measured at a certain temperature using a constant viscosity known The volume of liquid flowing through the capillary is calculated by the formula (1) to calculate the kinematic viscosity of the liquid. ν = Ct (1) Where. ν --- the kinematic viscosity of the liquid, mm2 · s-1; C - viscometer constant, mm2 · s-2; t --- a certain volume of liquid flow through the capillary time, s.4 Measurement performance requirementsThe first test of the viscometer, the subsequent verification and the use of inspection should meet the measurement performance requirements of Table 1 and Table 2. Table 1 Time Repetition and Constant Reproducibility Indicators Viscometer Uchiel, flat, Fenbu countercurrent Constant standard value ≤ 1mm2 · s-2 > 1mm2 · s-2 Time repeatability * 0.2% 0.3% 0.3% Constant reproducibility ** 0.3% 0.4% 0.4% * For countercurrent viscometer, with the same liquid twice the liquid measured value of the calculation. ** For countercurrent viscometers, calculate the two constant values measured with different liquids. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of JJG 155-2016_English be delivered?Answer: Upon your order, we will start to translate JJG 155-2016_English as soon as possible, and keep you informed of the progress.
