Power spectral density is the limiting mean square value in a given rectangular bandwidth divided by the bandwidth, as the bandwidth approaches zero. It is recommended that the minimum frequency range be from 3 to Hz, aztm overall amplitude s of the spectrum be not less than 0.

Two alternate test methods are presented: 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. Historical Version s – view previous versions of standard. Two alternate test methods are presented: 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. The two test methods are not necessarily equivalent and may not produce the same results.

Adjust the frequency of the vibration as necessary to maintain resonance. In the exclusive case of a sine wave, the rms value is 0.

Test duration, random spectrum, and damage criteria are to be specified by the user. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

The test surface shall be driven to move only in vertical linear motion throughout the desired range of amplitudes and frequencies.

Experience has shown that most individual transportation environments contain frequencies ranging from 3 Hz to Hz. 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. For spectrum examples, see Two alternate test methods are presented:.

Two alternate test methods are presented: 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.

Record any resonant responses of the product, repeat the cycle if necessary. 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 Therefore, the means used to fasten the product to the test surface must be of sufficient strength to keep it adequately secured.

A stroboscope or video system may be beneficial for visual examination of the specimen under test. When necessary to observe interior components of the product during tests, holes may be cut in noncritical area or noncritical panels may be removed.

See Section 6 for specific precautionary statements. See Section 6 for specific precautionary statements. If more applicable or accurate data are available, they should be aztm.

Referenced D35800 purchase separately The documents listed below are referenced within the subject standard but are not provided as part of e3580 standard. Stop the test method immediately if a dangerous condition should develop. D Terminology of Packaging and Distribution Environments.

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.

Acceleration levels sufficient to excite resonance normally range from 0. 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. This may become necessary if the response of a product would require design of an impractical or excessively costly shipping container. Any resonances with transmissibilities f3580 2 or greater may be considered significant.

Aztm a stroboscope; sensors and readouts; and visual, auditory, or other means as applicable to determine these resonances. This may become necessary if the response of a product would require design of an impractical or excessively costly shipping container.

Operating personnel shall remain alert to potential hazards and take necessary precautions for their safety. No other units of measurement are included in this standard. Significance and D3508 4. Starting at 3 Hz, vary the frequency of vibration at a continuous logarithmic rate of 0. The mounting devices shall not have significant resonances atsm the test frequency range. Since vibration damage is most likely to occur at product resonant frequencies, these resonances may be thought of as potential product fragility astj.

This may become necessary if the response of a product would require design of an impractical or excessively costly shipping container. 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.

Mount the accelerometer to either the top or bottom of the test surface, as close to the test item as possible, or in a location which produces data representative of table motion. By convention, acceleration is typically specified in terms of zero-to-peak d5380, while displacement is specified in terms of peak-to-peak amplitude.

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

Since vibration damage is most likely to occur at product resonant frequencies, these resonances may be thought of as potential product fragility points. Other, more suitable test procedures should be used for this purpose. 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. Relative motion between the test surface and the specimen mounting interface shall not be permitted.
