Introduction

The procedure to JJF1002 "national verification procedures write rules", JJF1001 "universal metering and fixed term Justice ", JJF1059" Evaluation and Expression of Uncertainty in Measurement "be revised based on norms. 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"; --- Deleted the original order "gravity value Appendix IV about the city." 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.
