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. D Terminology of Packaging and Distribution Environments.
This time is dependent upon the characteristics of the vibration test machine and control system, the setup, and the weight and characteristics of the test ashm. This may become necessary if the response of a product would require asstm of an impractical or excessively costly shipping container.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Since vibration damage is most likely to occur at product resonant e3580, these resonances may be thought of as potential product fragility points. Two alternate test methods are presented: 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 sstm.
Caution is necessary to avoid excessive pressure or mounting methods that could influence the characteristics of the product. Dwell time, acceleration level, and damage criteria are to be specified by the user. Sensor s may be applied as appropriate to measure data points of interest with the minimum possible alteration of the test specimen. Relative motion between the test surface and the specimen mounting interface shall not be permitted.
ASTM D3580 – 95(2015)
See Section 6 for specific precautionary statements. Stop the test asm immediately if a dangerous condition should develop. Operating personnel shall remain alert to potential hazards and take necessary precautions for their safety. If more applicable or accurate data are available, they should be substituted. If more applicable or accurate data are available, they should be substituted.
Acceleration levels sufficient to excite resonance normally range from 0. Record any resonant responses of the product, repeat the cycle if necessary. 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.
Any resonances with transmissibilities of 2 or greater may be considered significant. 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. D Terminology of Packaging and Distribution Environments. Use a stroboscope; sensors and readouts; and visual, auditory, or other axtm as applicable to determine these resonances.
Historical Version s – view previous versions of standard. Record any resonant responses of the product.
Whenever sufficient products are available, five or more replicate samples should be tested to improve the statistical reliability of the data obtained dd3580 practice E Starting at 3 Hz, vary the frequency of vibration at a continuous logarithmic rate of 0.
If more applicable or accurate data are available, they should be substituted.

It is recommended that the minimum frequency range be from 3 to Hz, the overall amplitude s of the spectrum be not less than 0. No other units of measurement are included in this standard.
Significance and Use 4. Other, more suitable test procedures should be used for this purpose. 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 test surface shall be driven to move only in vertical linear motion throughout the desired range of amplitudes and frequencies. 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. The mounting devices shall not have significant resonances in the test frequency range. For sine testing, the frequency sweep may be interrupted or reversed if necessary for d5380 time periods in order to properly identify a resonating component.
