Designation:D358095(Reapproved 2015)Standard Test Methods forVibration(Vertical Linear Motion)Test of Products1This standard is issued under the fixed designation D3580;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 These test methods cover the determination of reso-nances of unpackaged products and components of unpackagedproducts by means of vertical linear motion at the surface onwhich the product is mounted for test.Two alternate testmethods are presented:Test Method AResonance Search Using Sinusoidal Vibration,andTest Method BResonance Search Using Random Vibration.NOTE1The two test methods are not necessarily equivalent and maynot produce the same results.It is possible that tests using randomvibration may be more representative of the transport environment andmay be conducted more quickly than sine tests.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 these critical frequencies,when these products resonances are within the expectedtransportation environment frequency range.Since vibrationdamage is most likely to occur at product resonant frequencies,these resonances may be thought of as potential productfragility points.1.3 Information obtained from the optional dwell test meth-ods may be used to assess the fatigue characteristics of theresonating components and for product modification.This maybecome necessary if the response of a product would requiredesign of an impractical or excessively costly shipping con-tainer.1.4 These test methods do not necessarily simulate thevibration effects that the product will encounter in its opera-tional or in-use environment.Other,more suitable test proce-dures should be used for this purpose.1.5 Test levels given in these test methods represent thecorrelation of the best information currently available fromresearch investigation and from experience in the use of thesetest methods.If more applicable or accurate data are available,they should be substituted.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.See Section 6 forspecific precautionary statements.2.Referenced Documents2.1 ASTM Standards:2D996 Terminology of Packaging and Distribution Environ-mentsD4332 Practice for Conditioning Containers,Packages,orPackaging Components for TestingD4728 Test Method for Random Vibration Testing of Ship-ping ContainersE122 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 these testmethods,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 log10P1/P2.3.2.3 mean-squarethe time average of the square of thefunction.1These test methods are under the jurisdiction of ASTM Committee D10 onPackaging and are the direct responsibility of Subcommittee D10.13 on InteriorPackaging.Current edition approved April 1,2015.Published May 2015.Originallyapproved in 1977.Last previous edition approved in 2010 as D3580 95(2010).DOI:10.1520/D3580-95R15.2For 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 Defense Printing Service Detachment Office,Bldg.4D,NPM-DODSSP,700 Robbins Ave.,Philadelphia,PA 191115094.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.2.4 octavethe interval of two frequencies having a basicfrequency ratio of 2(1 octave=0.301 decade).3.2.5 overall g rmsthe square root of the integral of powerspectral density over the total frequency range.3.2.6power spectral density(PSD)a term used to quan-tify the intensity of random vibration in terms of mean-squareacceleration per unit of frequency.The units are g2/Hz(g2/cycles/s).Power spectral density is
