Introduction

This specification is for the measurement of technical regulations wet film thickness measurement gauge calibration. Preparation of this specification is based JJF 1071- 2010 "National calibration specifications write rules metering", JJF 1001-2011 "common measurement terms and definitions" and JJF 1059.1-2012 "Evaluation and Expression of Uncertainty in Measurement" as the basis and foundation, the newly developed measurement technology Regulation Fan. This specification is the main reference standard GB/T 13452.2-2008 "Paints and varnishes - Determination of film thickness." This specification is the first release. Wet film thickness measurement gauge calibration specification

1 Scope

This standard applies to the measurement range (0 ~ 3000) μm wet film thickness measurement gauge calibration. 2. References This specification references the following documents. Determination of GB/T 13452.2-2008 Paints and varnishes thickness For dated references, only the dated edition applies to this specification; undated reference documents Member, the latest edition (including any amendments) applies to this specification.

3 Terms

3.1 coating coating Single or continuous coating layer is applied repeatedly to the substrate after formation. 3.2 wet film thickness wet-filmthickness Measured immediately after coating the coating thickness of the wet coating.

4 Overview

Wet film thickness measurement gauge is a measuring tool for measuring wet film thickness. Press comb structure is divided into regulatory compliance and wheel Two kinds. Regulation is a comb made of corrosion resistant materials, edge gauge arranged a series of rectangles teeth. Each of its ends to form a side Baseline, baseline aligned along the crests and formed a baseline for measuring the height of the wet film thickness series. common A square, hexagonal, etc., structure type shown in Figure 1, is mainly used for measuring flat or slightly curved surfaces wet coating thickness. Regulation is a wheel made of a corrosion resistant material, and is composed of two identical rim diameter and the smaller diameter by an amount of the composition regulation. Rim having the same diameter and the outer concentric marked scale, each scale represents the position of the smaller rim (Face) Concentric rim (reference circle) and the height difference between the nominal value of the corresponding thickness. Structure type shown in Figure 2, is mainly used to measure the level Or even the entire curved surface of a wet coating thickness. ......
