Designation:F143497(Reapproved 2013)Standard Practice forEstimating the Performance of a Fuser Oil in anElectrostatic Copier or Printer1This standard is issued under the fixed designation F1434;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 practice covers a procedure for estimating theperformance of fuser oil in an electrostatic copier or printer.1.2 This practice describes a procedure for determiningfuser oil-related changes in the print quality measured duringtesting at specific intervals.1.3 Properties evaluated for all systems include odoremission,paper jam rate,paper wrap rate,paper crinkle rate,and fuser roller life.1.4 Properties evaluated for recirculating systems includechanges in viscosity,volatile matter content,and surfacetension.1.5 This practice describes a procedure for comparing theperformance of a subject fuser oil with that of a control fuseroil.1.6 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.7 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.For a specificprecautionary statement,see 8.3.1.2.Referenced Documents2.1 ASTM Standards:2D445 Test Method for Kinematic Viscosity of Transparentand Opaque Liquids(and Calculation of Dynamic Viscos-ity)D1331 Test Methods for Surface and Interfacial Tension ofSolutions of Paints,Solvents,Solutions of Surface-ActiveAgents,and Related MaterialsD4559 Test Method for Volatile Matter in Silicone FluidD4741 Test Method for Measuring Viscosity at High Tem-perature and High Shear Rate by Tapered-Plug ViscometerF335 Terminology Relating to Electrostatic ImagingF995 Practice for Estimating Toner Usage in Copiers Utiliz-ing Dry Two-Component Developer3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 fuser agenta specialized fuser oil designed to with-stand the higher temperatures encountered in certain high-speed copying machines.3.1.2 fuser cleaning unita mechanical assembly in acopier or printer used to clean the fuser rollers.3.1.3 fuser oila specifically formulated fluid,based onpolyorgano siloxane or equivalent,used in a fuser unit toprevent offsetting during the toner fixing process.3.1.4 fuser rolla heated roller that contacts the paper andtoner directly and is part of the fuser unit.3.1.5 fuser unita mechanical assembly in a copier orprinter used to fix the toner to the paper.The fuser unit caninclude an associated fuser oil applicator.3.1.6 non-recirculating systema fuser oil application sys-tem in which none of the fuser oil that has been removed fromthe reservoir is returned.3.1.7 recirculating systema fuser oil application systemthat removes the oil from a sump,applies a portion of the oilto the fuser unit,and returns the excess fuser oil to the sump.3.2 For definitions of other terms,refer to TerminologyF335.4.Summary of Practice4.1 A copier or printer is set up to standard operatingparameters and operated in a controlled job stream andenvironment.1This practice is under the jurisdiction of ASTM Committee F05 on BusinessImaging Products and is the direct responsibility of Subcommittee F05.04 onElectrostatic Imaging Products.Current edition approved April 1,2013.Published April 2013.Originallyapproved in 1992.Last previous edition approved in 2008 as F1434 97(2008).DOI:10.1520/F1434-97R13.2For 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 4.2 Standard OEM supplies,including toner and developer,fuser rollers,and fuser cleaning apparatus,are used andreplenished,as required,according to standard service proce-dures.4.3 The fuser oil to be evaluated is installed according to theservice procedure provided by the equipment manufacturer.Previously used fuser oil should be removed from the fuserunit.4.4 The test is conducted according to the procedure de-scribed in Practice F995.4.5 For recirculating systems,fuser oil samples are takenfrom the sump,and the surface tension,viscosity,and volatilematter content are determined using Test Methods D445,D1331,and at the beginning and at specific intervals during thetest.4.6 Print samples are taken during the test at the beginningand at specific intervals.The print quality is evaluated incomparison to initial copies,with reference to gloss uniformity,e
