The procedures in place JJG 154-1979 "standard capillary viscometer."
Compared with JJG 154-1979 version, the main content of this revision are as follows.
--- Increasing the "Introduction";
--- Modify the flow time measurement apparatus in the repeatability and reproducibility of the viscometer constant index, see Chapter 3 measurability
Energy requirements;
--- Increase the performance measurement indicators viscometer constant stability index, see Chapter 3 Measurement performance requirements;
--- Remove the second standard viscometer related content;
--- Modify the environmental conditions, see 5.1.3 verification of environmental conditions;
--- Increasing the recording format verification, test results and test certificate format notice format, see Appendix B, respectively,
Appendices C and D;
--- Deleted the original order "Appendix I viscometer Verification System";

Standard capillary viscometer test procedures
1 Scope
The order applies to the relative measurement standard capillary viscometer (hereinafter referred viscometer) initial verification, subsequent
Verification and use of checks.
2 Overview
Do not choose black viscometer Lott glass capillary viscometer, the structure shown in Figure 1. Viscometer is mainly used for calibration
Secondary standard viscosity fluid kinematic viscosity, and high accuracy for kinematic viscosity measurement. Viscometer test works as follows.
A certain amount of the national standard of known viscosity fluid viscosity charged subject viscometer, at a constant temperature, measure liquid
Body by gravity flow through the time required for a capillary, relative measurements, according to the equation (1) calculate the viscometer constant.
C = νt
(1)
Where.
C --- viscometer constant, mm2 · s-2;
ν --- standard viscosity fluid kinematic viscosity, mm2 · s-1;
T --- flow time, s.
