Starting at 3 Hz, vary the frequency of vibration at a continuous logarithmic rate of 0. This may become necessary if the response of a product would require design of an impractical or excessively costly shipping container.

It is possible that tests using random vibration may be more representative of the transport environment and may be conducted more quickly than sine tests. Acceleration levels sufficient to excite resonance normally range from 0. Link to Active This link will always route to the current Active version of the standard.

Two alternate test methods are presented: Since vibration damage is most likely to occur at product resonant frequencies, these resonances may be thought of as potential product fragility points.

D Terminology of Packaging and Distribution Environments. Relative motion between the test surface and the specimen mounting interface shall not be permitted.

ASTM D3580 – 95(2015)

The two test methods are not necessarily equivalent and may not produce the same results. Experience has shown that most individual transportation environments contain frequencies ranging from 3 Hz to Hz. Adjust the frequency of the vibration as necessary to maintain resonance.

They shall rigidly mount the product in a manner similar to the way in which it will be supported in its shipping container. See Section 6 for specific precautionary statements. In the exclusive case of a sine wave, the rms value is 0. 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 Other, more suitable test procedures should be used for this purpose.

When necessary to observe interior components of the product during tests, holes may be cut in noncritical area or noncritical panels may be removed.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. D Terminology of Packaging and Distribution Environments.

This may become necessary if the response of a d35800 would require design of an impractical or excessively costly shipping container. Since vibration damage is most likely to occur at product resonant frequencies, these resonances may be thought of as potential product fragility points. Use a stroboscope; sensors and readouts; and visual, auditory, or other means as applicable to determine these resonances. Sensor s may be applied as appropriate to measure data points 3d580 interest with the minimum possible alteration of the test specimen.

ASTM D – 95() Standard Test Methods for Vibration (Vertical Linear Motion) Test of Products

Record any resonant responses of the product, repeat the cycle if necessary. Caution is necessary to avoid excessive pressure or mounting methods that could influence the characteristics of the product. Active r3580 current version of standard.

No other units of measurement are included in this standard.

Record any resonant responses of the product. If more applicable or accurate data are available, they should be substituted.

Other, more suitable test procedures should be used for this purpose. Power spectral density is the limiting mean square value in a given rectangular bandwidth divided by the bandwidth, as the bandwidth approaches zero.

The determination of the resonant frequencies of the product may aid the packaging designer in adtm 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.

Therefore, the means used to fasten the product to the test surface must be of sufficient strength to keep it adequately secured. Test duration, random spectrum, and damage criteria are to be specified by the user. Two alternate test methods are presented: This time is dependent upon the characteristics of the vibration test machine and control system, the setup, and xstm weight and characteristics of the test specimen.

Parts and surfaces of the specimen may be marked for identification and reference. For sine testing, if different frequencies are recorded for each resonating component on the upsweep as compared to the downsweep a typical situationrecord both frequencies and the corresponding sweep direction. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. A stroboscope or video system may be beneficial for visual examination of the specimen under test.

Significance and Use 4. Link to Active This link will always route d35580 the current Active version of the standard. 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 amplitude. See Section 6 for specific precautionary statements. 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.

Two alternate test methods are presented:.

The mounting devices shall not have significant resonances in the test frequency range. If more applicable or accurate data are available, they should be substituted. The instantaneous magnitudes of random vibration are not prescribed for any given instant in time, but instead are prescribed by a probability distribution function, the integral of which over a given magnitude range will give the probable percentage of the time that the magnitude will fall within that range.

Historical Version s – view previous versions of standard. Any resonances with transmissibilities of 2 or greater may be considered significant. Two alternate test methods are presented:.
