Designation:E194798(Reapproved 2014)Standard Specification forAnalytical Data Interchange Protocol for ChromatographicData1This standard is issued under the fixed designation E1947;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 specification covers a standardized format forchromatographic data representation and a software vehicle toeffect the transfer of chromatographic data between instrumentdata systems.This specification provides protocol designed tobenefit users of analytical instruments and increase laboratoryproductivity and efficiency.1.2 The protocol in this specification provides a standard-ized format for the creation of raw data files or results files.This standard format has the extension“.cdf”(derived fromNetCDF).The contents of the file include typical headerinformation like instrument,column,detector,and operatordescription followed by raw or processed data,or both.Oncedata have been written or converted to this protocol,they canbe read and processed by software packages that support theprotocol.1.3 The software transfer vehicle used for the protocol inthis specification is NetCDF,which was developed by theUnidata Program and is funded by the Division ofAtmosphericSciences of the National Science Foundation.21.4 The protocol in this specification is intended to(1)transfer data between various vendors instrument systems,(2)provide LIMS communications,(3)link data to documentprocessingapplications,(4)linkdatatospreadsheetapplications,and(5)archive analytical data,or a combinationthereof.The protocol is a consistent,vendor independent dataformat that facilitates the analytical data interchange for theseactivities.1.5 The protocol consists of:1.5.1 This specification on chromatographic data,whichgives the full definitions for each one of the generic chromato-graphic data elements used in implementation of the protocol.It defines the analytical information categories,which are aconvenient way for sorting analytical data elements to makethem easier to standardize.1.5.2 Guide E1948 on chromatographic data,which givesthe full details on how to implement the content of the protocolusing the public-domain NetCDF data interchange system.Itincludes a brief introduction to using NetCDF.It is intended forsoftware implementors,not those wanting to understand thedefinitions of data in a chromatographic dataset.1.5.3 NetCDF Users Guide.2.Referenced Documents2.1 ASTM Standards:3E1948 Guide for Analytical Data Interchange Protocol forChromatographic Data2.2 Other Standard:NetCDF Users Guide42.3 ISO Standards:5ISO 2014-1976(E)Writing of Calendar Dates in All-Numeric FormISO 3307-1975(E)Information InterchangeRepresen-tations of Time of the DayISO 4031-1978(E)Information InterchangeRepresen-tations of Local Time Differentials3.Terminology3.1 Definitions for Administrative Information ClassThese definitions are for those data elements that are imple-mented in the protocol.See Table 1.3.1.1 administrative-commentscomments about the data-set identification of the experiment.This free test field is foranything in this information class that is not covered by theother data elements in this class.1This specification is under the jurisdiction of ASTM E13 on MolecularSpectroscopy and Separation Science and is the direct responsibility of E13.15 onAnalytical Data.Current edition approved Aug.1,2014.Published August 2014.Originallyapproved in 1998.Last previous edition approved in 2009 as E1947 98(2009).DOI:10.1520/E1947-98R14.2For more information on the NetCDF standard,contact Unidata at http:/www.unidata.ucar.edu.3For 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.4Available from Russell K.Rew,Unidata Program Center,University Corpora-tion for Atmospheric Research,P.O.Box 3000,Boulder,CO 80307-3000,http:/www2.ucar.edu.5Available from International Organization for Standardization(ISO),1,ch.dela Voie-Creuse,CP 56,CH-1211,Geneva 20,Switzerland,http:/www.iso.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.1.2 company-method-IDinternal method ID of thesample analysis method used by the company.3.1.3 company-method-nameinternal method name of thesample analysis method used by the company.3.1.4 dataset-completenessindicates which analytical in-formation categories are contained in the dataset.The stringshould exactly list the category values,as appropriate,as one ormore of the following“C1+C2+C3+C4+C5,”in a stringseparated by plus(+)signs.This data element is used to checkfor completeness of the analytical dataset being tr
