Acceleration levels sufficient to excite resonance normally range from 0. D Terminology of Packaging and Distribution Environments.

Dwell time, acceleration level, and damage criteria are to be specified by the user. 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 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.

D Terminology of Packaging and Distribution Environments. This may become necessary if the response of a product would require design of an impractical or excessively costly shipping container. Active view current version of standard. 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.

If more applicable or accurate data are available, they should be substituted.

The mounting devices shall not have significant resonances in the test frequency range. This may become necessary if the response of a product would require design of an impractical or excessively costly shipping container.

In the exclusive case of a sine wave, the rms value is 0. Power spectral density is the limiting mean square value in a given rectangular bandwidth divided by the bandwidth, as the bandwidth approaches zero.

They shall rigidly mount the product in a manner similar to the way in which it will be supported in its shipping container.

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. See Section 6 for specific precautionary statements. Record any resonant responses of the product.

Operating personnel shall remain alert to potential hazards and take necessary precautions for their safety. Historical Version s – view previous versions of standard. 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. Any resonances with transmissibilities of 2 or greater may be considered significant.

It is recommended satm the minimum frequency range be from 3 to Hz, the overall amplitude s of the spectrum sstm not less than 0. Two alternate test methods are presented: Therefore, the means used to fasten the product to the test surface must be of sufficient strength to keep it adequately secured. No other units of measurement are included axtm this standard. Two alternate test methods are presented: This time is dependent upon the characteristics of the vibration test machine and control astmm, the setup, and the weight and characteristics of the test specimen.

Two alternate test methods are presented: 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.

Adjust the frequency of the vibration as necessary to maintain resonance. See Section 6 for specific precautionary statements. Since vibration damage is most likely to occur at product resonant frequencies, these resonances may be thought of as potential product fragility points. Since vibration damage is most likely to occur at product resonant frequencies, these resonances may be thought of as potential product fragility points.
