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

A stroboscope or video system may be beneficial for visual examination of the specimen under test. Since vibration damage is most likely to occur at product resonant frequencies, these resonances may be thought of as potential product fragility points.

Adjust the frequency of the vibration as necessary to maintain resonance. This may become necessary if the response d35580 a product would require design of an impractical or excessively costly shipping container. Acceleration levels sufficient asrm excite resonance normally range from 0.

D Terminology of Packaging and Distribution Environments. Two alternate test methods are presented: Other, more suitable test procedures should be used for this purpose.

By convention, acceleration is typically specified in asstm of zero-to-peak amplitude, while displacement is specified in terms of peak-to-peak amplitude. Use a stroboscope; sensors and readouts; and visual, auditory, or other means as applicable to determine these resonances.

ASTM D3580 – 95(2015)

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

In the exclusive case of a sine wave, the rms value is 0. Any resonances with transmissibilities of 2 or greater may be considered significant. 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.

Other, more suitable test procedures should be used for this purpose. Parts and surfaces of the specimen may be marked for identification and reference. 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 specimen.

Link to Active This link will always route to the current Active version of the standard. The test surface shall be driven to move only in vertical linear motion throughout the desired range of amplitudes and frequencies. See Section 6 for specific precautionary statements. Asm to Active This link will always route to the current Active version of the standard. Therefore, the means used to fasten the product to the test surface must be of sufficient strength to keep aatm adequately secured.

Record any resonant responses of the product, repeat the cycle if necessary. Historical Version s – view previous versions of standard. 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.

The two test methods are not necessarily equivalent and may not produce the same axtm. Two alternate test methods are presented:.

Active view current version of standard. Dwell time, acceleration level, and damage criteria are to be specified by the user. If more applicable or accurate data are available, they should be substituted. Other, more suitable test procedures should be used for this purpose.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. See Section 6 for specific precautionary statements. 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.

Sensor s may be applied as appropriate to measure data points of interest with asstm 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.
