Introduction

This specification is a metrological specification for needle gauge and sheet gauge calibration. The development of this specification JJF 1071-2010 "Rules for the Preparation of National Metrological Calibration Standards", JJF 1001-2011 "General Metrological Terms and Definitions "JJF 1059.1-2012" measurement uncertainty assessment and representation "as the basic series of regulations. This specification is the first release. Standard Specification for Needle - like, Sheet - like Calibrator Calibration

1 Scope

This specification applies to the cement concrete aggregate and the construction of pebbles, gravel needle and flake particle classification screening needle Calibration of the gauge and sheet gauge.

3 Overview

Needle-like, sheet-like gauge is the cement concrete aggregate and construction of pebbles, gravel in the 4.75mm ~ 37.5mm Between the needle and the granular particles for grading screening of measuring instruments, it is widely used in construction engineering laboratory measurement needle And the size of the flaky particles. The needle gauge consists of a substrate and seven cylindrical columns, along the longitudinal axis of the substrate, two adjacent The distance between the columns and the bus bars is the spacing between adjacent columns. The shape of the needle gauge is shown in Fig. The sheet gauge is composed of a bracket and a standard plate, and there are six different specifications of the standard hole evenly distributed on the specification plate, Specified hole shape consists of three parts. the middle part of the rectangular, rectangular width is the standard hole width; both ends Divided into the diameter of the middle of the circular rectangle; along the longitudinal axis of the standard hole, the maximum distance between the two arcs is Standard hole length. The outline structure of the sheet gauge is shown in Fig. Figure 1 needle gauge gauge outline structure diagram 1 on-board surface; 2-gauge column; 3-adjacent string spacing; 4-gauge column height
