Designation:D653700(Reapproved 2014)Standard Practice forInstrumented Package Shock Testing For Determination ofPackage Performance1This standard is issued under the fixed designation D6537;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 methods for obtaining measuredshock responses using instrumentation for an actual or simu-lated product package system when subjected to defined shockinputs to measure package performance.1.2 This practice establishes methods for obtaining mea-sured shock data for use with shock and impact test methods.It is not intended as a substitute for performance testing ofshipping containers and systems such as Practice D4169.1.3 This practice will address acceleration measuring tech-niques.Other ways of measuring shock impacts,such as highspeed video,are not covered by this practice.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.2.Referenced Documents2.1 ASTM Standards:2D996 Terminology of Packaging and Distribution Environ-mentsD3332 Test Methods for Mechanical-Shock Fragility ofProducts,Using Shock MachinesD4003 Test Methods for Programmable Horizontal ImpactTest for Shipping Containers and SystemsD4169 Practice for Performance Testing of Shipping Con-tainers and SystemsD5276 Test Method for Drop Test of Loaded Containers byFree FallD5277 Test Method for Performing Programmed HorizontalImpacts Using an Inclined Impact TesterD5487 Test Method for Simulated Drop of Loaded Contain-ers by Shock MachinesD6055 Test Methods for Mechanical Handling of UnitizedLoads and Large Shipping Cases and CratesD6179 Test Methods for Rough Handling of Unitized Loadsand Large Shipping Cases and Crates2.2 ISO Standard:10012 Quality Assurance for Measuring Equipment33.Terminology3.1 Definitions:3.1.1 General definitions for packaging and distribution arefound in Terminology D996.3.2 Definitions of Terms Specific to This Standard:3.2.1 accelerometera sensor that converts accelerationinto a proportional electric signal for measurement.3.2.2 coeffcient of restitutionthe ratio of the reboundvelocity to the impact velocity.3.2.3 complex waveformacceleration versus time graphrepresenting the responses of many different spring/masssystems when subjected to an impact.Also referred to as acomplex shock-pulse.3.2.4 faired accelerationthe amplitude representing theprimary or intended response system in a complex shock pulse.3.2.5 fairingthe graphical smoothing of a recorded pulseby visually estimating the amplitude of the primary waveformwhen high frequency responses are also present.3.2.6 peak accelerationthe maximum absolute value ofacceleration which occurred during the shock pulse.3.2.7 primary waveformacceleration versus time graphrepresenting the response of the spring/mass system of interestwhen subjected to an impact.Also referred to as a primaryshock-pulse.3.2.8 pulse durationthe amount of time the shock accel-eration is beyond a reference level.This level is generally takenas 10%of the pulse peak acceleration(not the zero baseline)to most accurately represent the effective duration and fre-quency of the pulse.1This practice is under the jurisdiction of ASTM Committee D10 on Packagingand is the direct responsibility of Subcommittee D10.13 on Interior Packaging.Current edition approved April 1,2014.Published April 2014.Originallyapproved in 2000.Last previous edition approved in 2006 as D6537 00(2006).DOI:10.1520/D6537-00R14.2For 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.3Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.2.9 velocity changethe sum of the velocity at impact andthe rebound velocity.4.Significance and Use4.1 This practice is intended to provide the user with aprocess to obtain data on package performance when apackaged product is subjected to shock.These measures can beused to quantify or qualify a package system.4.2 Data from this practice may provide a measure of apackages ability to mitigate the various levels of shippingshock or impact hazards.These measures may be used toprescribe a mode of shipping and handling that will not inducedamage to the packaged product or to define the required levelsof protection that must be pro
