It is the responsibility of the user of this standard to establish dd3580 safety and health practices and determine the applicability of regulatory limitations prior to use.

The determination of the resonant frequencies of the product may aid the packaging designer in determining the proper packaging system to provide adequate protection for the product, as well as providing an understanding of the complex interactions between the components of the product as they relate to expected transportation vibration inputs.

The determination of the resonant frequencies of the product may aid the packaging designer in determining the proper packaging system to provide adequate protection for the product, as well as providing an understanding of the complex interactions between the components of the product as they relate to expected transportation vibration inputs. Starting at 3 Hz, vary the frequency of vibration at a continuous logarithmic rate of 0.

It is recommended that the asmt frequency range be from 3 to Hz, the overall amplitude s of the spectrum be not less than 0. Link to Active This link will always route to the current Active version of the standard. In the exclusive case of a sine wave, the rms value is 0. This may become necessary if the response of a product would require design of an impractical or excessively costly shipping container.

Sensor s may be applied as appropriate to measure data points of interest with the minimum possible alteration of the test specimen.

This may become necessary if the response of a product would require design of an impractical or excessively costly shipping container. Two alternate test methods are presented: Relative motion between the test surface and the specimen mounting interface shall not dd3580 permitted.

Use a stroboscope; sensors and readouts; and visual, auditory, or other means as applicable to determine these resonances. Parts and surfaces of the specimen may be marked for identification and reference. If more applicable or accurate data are available, they should be substituted. Operating personnel shall remain alert to potential hazards and take necessary precautions for their safety.

This may become necessary if the response of a product would require design of an impractical or excessively costly shipping container. Acceleration levels sufficient to excite resonance normally range from 0. Two alternate test methods are presented:. When necessary to observe interior components of the product during tests, holes may be cut in noncritical area or noncritical panels may be removed. Two alternate test methods are presented: The two test methods are not necessarily equivalent and may not produce the same results.

Other, more suitable test procedures should be used for this purpose.

Since vibration damage is most likely to occur at product resonant frequencies, these resonances may be thought of as potential product fragility points. Significance and Use 4.

Two alternate test methods are presented: Historical Version s – view previous versions of standard. Power spectral density is the limiting mean square value in a given rectangular bandwidth divided by the bandwidth, as the bandwidth approaches zero.

ASTM D3580 – 95(2015)

ashm Record any resonant responses of the product, repeat the cycle if necessary. Since vibration damage is most likely to occur at product resonant frequencies, these resonances may be thought of as potential product fragility points.

Caution is necessary to avoid excessive pressure or mounting methods that could influence the characteristics of the product. If more applicable or accurate data are available, they should be substituted. By convention, acceleration is typically specified in terms of zero-to-peak amplitude, while displacement is specified in terms of peak-to-peak ast.

It is recommended that tests be initiated at least 6 dB below full level and incremented in one or more subsequent steps to full test level. Whenever sufficient products are available, five or more replicate samples should be tested to improve the statistical reliability of the data obtained see practice E The mounting devices shall not have significant resonances in the test frequency range.

Other, more suitable test procedures should be used for this purpose. D Terminology of Packaging and Distribution Environments.

Test duration, random spectrum, and damage criteria are to be specified by the user. Two alternate test methods are presented:.

If more applicable or accurate data are available, they should be substituted. Record any resonant responses of the product. It is the responsibility of the user of c3580 standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

No other units of measurement are included in this standard.
