Designation:D511222Standard Test Method forVibration(Horizontal Linear Motion)Test of Products1This standard is issued under the fixed designation D5112;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 resonancesof unpackaged products and components by means of horizon-tal linear motion applied at the surface on which the product ismounted.For vertical vibration testing of products see TestMethod D3580.Two alternate test methods are presented:1.1.1 Test Method AResonance Search Using SinusoidalVibration,and1.1.2 Test Method BResonance Search Using RandomVibration.NOTE1These two test methods are not necessarily equivalent andmay not produce the same results.1.2 This information may be used to examine the responseof products to vibration for product design purposes,or for thedesign of a container or interior package that will minimizetransportation vibration inputs at the critical frequencies,whenthese product resonances are within the expected transportationenvironment frequency range.Since vibration damage is mostlikely to occur at product resonant frequencies,these may bethought of as potential product fragility points.1.3 Information obtained from the optional sinusoidal dwelland random test methods may be used to assess the fatiguecharacteristics of the resonating components and for productmodification.This may become necessary if a productsresponse would require design of an impractical or excessivelycostly shipping container.1.4 This test method does not necessarily simulate vibrationeffects the product will encounter in operating or end-useenvironments.Other,more suitable test procedures should beused for this purpose.1.5 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.6 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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.For specific precautionary statements,see Section 61.7 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D996 Terminology of Packaging and Distribution Environ-mentsD3580 Test Methods for Vibration(Vertical Linear Motion)Test of ProductsD4332 Practice for Conditioning Containers,Packages,orPackaging Components for TestingE122 Practice for Calculating Sample Size to Estimate,WithSpecified Precision,the Average for a Characteristic of aLot or Process2.2 Military Standard:MIL STD 810,Method 514,Vibration33.Terminology3.1 DefinitionsFor definitions of terms used in this testmethod,see Terminology D996.3.2 Definitions of Terms Specific to This Standard:3.2.1 decadethe interval of two frequencies having a basicfrequency ratio of 10(1 decade=3.322 octaves).3.2.2 decibel(dB)a logarithmic expression of the relativevalues of two quantities.For relative power measurements,thedB value equals 10 times the base-10 logarithm of the ratio ofthe two quantities,that is,dB=10 log10P1P2.1This test method is under the jurisdiction of ASTM Committee D10 onPackaging and is the direct responsibility of Subcommittee D10.13 on InteriorPackaging.Current edition approved Oct.1,2022.Published October 2022.Originallyapproved in 1990.Last previous edition approved in 2015 as D5112 98(2015).DOI:10.1520/D5112-22.2For 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 Standardization Documents Order Desk,Bldg.4 Section D,700Robbins Ave.,Philadelphia,PA 19111-5094,Attn:NPODS.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.13.2.3 horizontal linear motionmotion occurring essen-tially along a straight horizontal line,with no significantvertical or off-axis components.3.2.4 mean-squarethe time average of the square of thefunction.3.2.5 octavethe interval of two
