Designation:D527392(Reapproved 2012)Standard Guide forAnalysis of Propylene Concentrates1This standard is issued under the fixed designation D5273;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide covers a list of the major grades of propyleneconcentrates produced in North America.It includes possiblecomponents and test methods,both ASTM and other,eitheractually used,or believed to be in use,to test for theseproperties.This guide is not intended to be used or construedas a set of specifications for any grade of propylene concen-trate.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D2163 Test Method for Analysis of Liquefied Petroleum(LP)Gases and Propene Concentrates by Gas Chromatog-raphyD2384 Test Methods for Traces of Volatile Chlorides inButane-Butene MixturesD2504 Test Method for Noncondensable Gases in C2andLighter Hydrocarbon Products by Gas ChromatographyD2505 Test Method for Ethylene,Other Hydrocarbons,andCarbon Dioxide in High-Purity Ethylene by Gas Chroma-tographyD2712 Test Method for Hydrocarbon Traces in PropyleneConcentrates by Gas ChromatographyD3227 Test Method for(Thiol Mercaptan)Sulfur inGasoline,Kerosine,Aviation Turbine,and Distillate Fuels(Potentiometric Method)D3246 Test Method for Sulfur in Petroleum Gas by Oxida-tive MicrocoulometryD3700 Practice for Obtaining LPG Samples Using a Float-ing Piston CylinderD4178 Practice for Calibrating Moisture AnalyzersD4468 Test Method for Total Sulfur in Gaseous Fuels byHydrogenolysis and Rateometric ColorimetryD4629 Test Method for Trace Nitrogen in Liquid PetroleumHydrocarbons by Syringe/Inlet Oxidative Combustion andChemiluminescence DetectionD4864 Test Method for Determination of Traces of Metha-nol in Propylene Concentrates by Gas Chromatography3.Terminology3.1 Definitions:3.1.1 outaging,npractice of removing a portion of liquidcontents from a conventional sampling cylinder after filling toprovide expansion room.3.1.2 propylene concentrate,nhydrocarbon product con-taining more than 50%propylene.3.1.2.1 DiscussionGrades of propylene concentrates listedin this guide are:polymer,99.0%minimum propylene content;chemical,92.0%;and refinery,60%.3.2 Abbreviations:3.2.1 AgDDC,nsilver diethyldithiocarbamate.3.2.2 GC,ngas chromatograph.3.2.3 GC-AED,ngas chromatography atomic emissiondetector.3.2.4 GC-ECD,ngas chromatography electron capturedetector.3.2.5 GC-FPD,ngas chromatography flame photometricdetector.3.2.6 GC-PID,ngas chromatography photoionization de-tector.3.2.7 GC-SCD,ngas chromatography sulfur chemilumi-nescent detector.3.2.8 IC,nion chromatography.3.2.9 ICP-MS,ninductively coupled plasma-mass spec-trometry.3.2.10 LPG or LP gases,nliquefied petroleum gas.1This guide is under the jurisdiction of ASTM Committee D02 on PetroleumProducts and Lubricants and is the direct responsibility of Subcommittee D02.D0.03on Propylene.Current edition approved Dec.1,2012.Published December 2012.Originallyapproved in 1992.Last previous edition approved in 2007 as D527392(2007).DOI:10.1520/D5273-92R12.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.Significance and Use4.1 This guide is intended to provide information on thelikely composition of propylene concentrates and on probableways to test them.Since there are currently no ASTM testmethods for determining all components of interest,this guideprovides information on other potentially available test meth-ods.4.2 Although this guide is not to be used for specifications,it can provide a starting point for parties to develop mutuallyagreed upon specifications which meet their respective require-ments.It can also be used as a starting point in finding suitabletest methods for determining various components of propylene.5.Sampling5.1 GeneralSample propylene concentrates are to be ana-lyzed for trace components by a technique that minimizes oreliminates losses of light components and concentration ofheavy ones.The sections below list some different samplingmethods and principles.However,it is not the intent of thisguide to list procedures that are applicable to all sampling
