1 Scope

This procedure applies to the flow-out cups of Tu-1, Tu-4, Portable Tu-4, ISO Series and Ford Series. Viscosity meter (hereinafter referred to as viscometer) for the first verification, subsequent verification and in-use inspection.

2 reference files

This procedure refers to the following documents. GB/T 1723 coating viscosity measurement method GB/T 6753.4 Paint and varnish with outflow cup to determine the outflow time Standard Test Method for Viscosity Determination by ASTMD1200 Ford Viscosity Cup Method (StandardTestMethodfor ViscositybyFordViscosityCup) For dated references, only the dated version applies to this Code; any undated quotation The latest version (including all amendments) applies to this procedure.

3 Overview

Viscosity meter is the most widely used viscosity measuring equipment in the coating industry. It is economical and easy to operate. specialty. Its working principle is to use the sample to generate flow under the action of its own gravity, with a certain amount of sample in a certain The viscosity of the sample is described by the time that it flows out of the viscometer at temperature.

4 Metrological performance requirements

The first verification, subsequent verification and in-use inspection of the viscometer shall meet the requirements of Table 1. Table 1 Measurement performance requirements Viscometer measuring Repeatability Correction factor Recurrence Correction factor error Tu-1, Tu-4, portable Paint-4, Ford Series ISO series ≤2% ≤3% ≤5% ≤3%

5 General technical requirements

The inner surface of the viscometer is smooth and must not have any willows and scratches. The inner wall of the viscometer outflow pipe shall be smooth without burrs, and the connection between the outflow pipe and the inner wall of the cup shall be smooth, after replacing the outflow pipe There must be no gaps. ......
