Introduction

This specification is based on JJF 1071-2010 "Rules for Writing National Metrology Calibration Specifications", JJF 1001-2011 "General "Using Measurement Terms and Definitions" and JJF 1059:1-2012 "Evaluation and Expression of Measurement Uncertainty" as basic specifications: OK to make: The preparation of this specification refers to JJG956-2013 "Atmospheric Sampler", JJF 1190-2008 "Dust Particle Meter" Counter Calibration Specifications" and JJF 1562-2016 "Condensation Nucleus Particle Counter Calibration Specifications": This specification is released for the first time: Aerosol Dilutor Calibration Specifications

1 Scope

This specification is applicable to flow-limited aerosol dilution with a flow range of (1~30)L/min and a dilution ratio of 1~300: Calibration of aerosol diluters and flow-type aerosol diluters: Other aerosol diluters can be calibrated with reference to this specification:

This specification references the following documents: JJG956-2013 Atmospheric sampler JJF 1190-2008 Calibration specifications for dust particle counters JJF 1562-2016 Calibration Specifications for Condensation Nucleus Particle Counters GB/T 6682-2008 Specifications and test methods for water used in analytical laboratories For dated references, only the dated version applies to this specification; for undated references, only the dated edition applies: The latest version (including all modification orders) shall apply to this regulation:

3 Terminology and units of measurement

The number of particulate matter per unit volume of gas, the unit is L-1: 3:2 Dilution ratio dilutionratio The ratio of the number of particles per unit volume of the air inlet to the number of particles per unit volume of the air outlet, dimensionless:

4 Overview

The aerosol diluter (hereinafter referred to as the diluter) is used to quantitatively dilute aerosol samples containing particulate matter from In order to reduce the concentration of particulate matter in the sample in an equal proportion, according to the working principle, the diluter can be divided into a flow-limiting diluter and a flow-type diluter: Volumetric diluter: The working principle of the flow-limiting diluter is shown in Figure 1: When the aerosol sample containing particulate matter enters the inlet of the diluter, It is divided into two paths, and the samples of the two paths flow through the capillary gas path and the gas path containing the high-efficiency filter respectively according to a certain proportion: The two samples are mixed to obtain a diluted sample: The working principle of the flow diluter is shown in Figure 2: The aerosol sample containing particulate matter and the clean gas sample are A certain proportion enters the dilution chamber of the instrument from the diluter inlet and is mixed evenly in the chamber: The mixed sample was The aerosol outlet of the diluter is quantitatively output, and the excess gas sample is discharged through other outlets:
