Revised.
Compared with JJG 155-1991, the main contents of this revision are as follows.
--- increase "Introduction";
--- increase the measurement performance indicators of viscometer constant stability indicators, see Table 2;
--- delete the original program "Table 2 standard solution" related content;
- to remove the limits of the original test area for the verification temperature range;
--- increase the stability of the constant calculation method, see "6.2.2.5 constant stability";
--- delete the original program example;
--- delete the original procedure "Appendix 1 standard viscosity of the liquid value of the method";
--- modify the original procedure "Appendix 2 at 20 ℃ test capillary viscometer standard viscosity liquid grade" as "Appendix
A viscosity standard selection reference ";
--- Modify the original record and certificate format, see Appendix B and Appendix C.

Verification of working capillary viscometer
1 Scope
This 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.

3 Overview
Viscometer 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 requirements
The 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.
