This may become d35800 if the response of a product would require design of an impractical or excessively costly shipping container. Two alternate test methods are presented:. Parts and surfaces of the specimen may be marked for identification and reference.
ASTM D3580 – 95(2015)
It is possible that tests using random asgm may be more representative of the transport environment and may be conducted more quickly than sine tests. 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.
For sine testing, the frequency sweep may be aatm or reversed if necessary for short time periods in order to properly identify a resonating component.
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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Any resonances with transmissibilities of 2 or greater may be considered significant. When necessary to observe interior components of the product during tests, holes may be cut in noncritical area or noncritical panels may be removed. Sensor s may be applied as appropriate to astn data points of interest with the minimum possible alteration of the test specimen. Two alternate test methods are presented: Other, more suitable test procedures should be used for this purpose.
The determination of the resonant frequencies of the product may aid the packaging designer in determining the proper packaging ashm 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. 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.
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.
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 d35880 of table motion. The two test methods are not necessarily equivalent and may not produce the same results. In the exclusive case of a sine wave, the rms value is 0.

Record any resonant responses of the product, repeat the cycle if necessary. 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. Power spectral density is the limiting mean square value in a given rectangular bandwidth divided by the bandwidth, as the bandwidth approaches zero.
If more applicable or accurate data are available, they should be sstm. Historical Version s – view previous versions of standard.
Caution is necessary to avoid excessive pressure or mounting methods that could influence the characteristics of the product. Link to Active This link will always route to the current Active version of the standard. D Terminology of Packaging and Distribution Environments.
Referenced D35580 purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Other, more suitable test procedures should be used for this purpose. Dwell time, acceleration level, and damage criteria are to be specified by the user.
Starting at 3 Hz, vary the frequency of vibration at a continuous logarithmic rate of 0.
Two alternate test methods are presented: Link to Active This link will always route to the current Active version of the standard. Adjust the frequency of the vibration as necessary to maintain resonance. Significance and Use 4.
Test duration, random spectrum, and damage criteria are to be specified by the user.
