Designation:C133717Standard Test Method forCreep and Creep Rupture of Continuous Fiber-ReinforcedAdvanced Ceramics Under Tensile Loading at ElevatedTemperatures1This standard is issued under the fixed designation C1337;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 test method covers the determination of the time-dependent deformation and time-to-rupture of continuousfiber-reinforced ceramic composites under constant tensileloading at elevated temperatures.This test method addresses,but is not restricted to,various suggested test specimengeometries.In addition,test specimen fabrication methods,allowable bending,temperature measurements,temperaturecontrol,data collection,and reporting procedures are ad-dressed.1.2 This test method is intended primarily for use with alladvanced ceramic matrix composites with continuous fiberreinforcement:unidirectional(1-D),bidirectional(2-D),andtridirectional(3-D).In addition,this test method may also beused with glass matrix composites with 1-D,2-D,and 3-Dcontinuous fiber reinforcement.This test method does notaddress directly discontinuous fiber-reinforced,whisker-reinforced,or particulate-reinforced ceramics,although the testmethods detailed here may be equally applicable to thesecomposites.1.3 Values expressed in this test method are in accordancewith the International System of Units(SI)and IEEE/ASTM SI10.1.4 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.Hazard statementsare noted in 7.1 and 7.2.2.Referenced Documents2.1 ASTM Standards:2C1145 Terminology of Advanced CeramicsC1275 Test Method for Monotonic Tensile Behavior ofContinuous Fiber-Reinforced Advanced Ceramics withSolid Rectangular Cross-Section Test Specimens at Am-bient TemperatureD3878 Terminology for Composite MaterialsE4 Practices for Force Verification of Testing MachinesE6 Terminology Relating to Methods of Mechanical TestingE83 Practice for Verification and Classification of Exten-someter SystemsE220 Test Method for Calibration of Thermocouples ByComparison TechniquesE230 Specification and Temperature-Electromotive Force(EMF)Tables for Standardized ThermocouplesE337 Test Method for Measuring Humidity with a Psy-chrometer(the Measurement of Wet-and Dry-Bulb Tem-peratures)E1012 Practice for Verification of Testing Frame and Speci-men Alignment Under Tensile and Compressive AxialForce ApplicationIEEE/ASTM SI 10 American National Standard for Use ofthe International System of Units(SI):The Modern MetricSystem3.Terminology3.1 Definitions:3.1.1 The definitions of terms relating to tensile testingappearing in Terminology E6 apply to the terms used in thistest method.The definitions relating to advanced ceramicsappearing in Terminology C1145 apply to the terms used in thistest method.The definitions of terms relating to fiber rein-forced composites appearing in Terminology D3878 apply to1This test method is under the jurisdiction of ASTM Committee C28 onAdvanced Ceramics and is the direct responsibility of Subcommittee C28.07 onCeramic Matrix Composites.Current edition approved Feb.1,2017.Published February 2017.Originallyapproved in 1996.Last previous edition approved in 2015 as C1337 10(2015).DOI:10.1520/C1337-17.2For 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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 the terms used in this test method.Additional terms used inconjunction with this test method are defined in the following:3.1.2 ceramic matrix compositematerial consisting of twoor more materials(insoluble in one another),in which themajor,continuous component(matrix component)is a ceramic,while the secondary component/s(reinforcing component)maybe ceramic,glass-ceramic,glass,metal,or organic in nature.These components are combined on a macroscale to form auseful engineering material possessing certain properties orbehavior not possessed by the individual constituents.C11453.1.3 continuous fiber-reinforced ceramic matrix composite(CFCC)ceramic matrix composite in which t
