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. Adjust the frequency of the vibration as necessary to maintain resonance.
For spectrum examples, see Other, more suitable test procedures should be used for this purpose. Record any resonant responses of the product, repeat the cycle if necessary.
They shall rigidly mount the product in a manner similar to the way in which it will be supported in its shipping container. Operating astmm shall remain alert to potential hazards and take necessary precautions for their safety.
Other, more suitable test e3580 should be used for this purpose. 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.
Record any resonant responses astj the product. See Section 6 for specific precautionary statements. Therefore, the means used to fasten the product to the test surface must be of sufficient strength to keep it adequately secured. Relative motion between the test surface and the specimen mounting interface shall not be permitted.

Any resonances with transmissibilities of 2 or greater may be considered significant. Since vibration damage is most likely to occur at product resonant frequencies, these resonances may be thought of as potential product fragility points.
The instantaneous magnitudes of random vibration are not prescribed for any given instant in time, but instead are prescribed by a probability distribution function, the integral of which over a given magnitude range will give the probable percentage of the time that the magnitude will fall within that range.
Link to Active This link will always route to the current Active version of the standard. Stop the test method immediately if e3580 dangerous condition should develop. Experience has shown that most individual transportation environments contain frequencies ranging from 3 Hz to Hz.
ASTM D – 95() Standard Test Methods for Vibration (Vertical Linear Motion) Test of Products
The test surface shall be driven to move only in vertical linear motion throughout the desired range of amplitudes and frequencies. Caution is necessary to avoid excessive pressure or mounting methods that could influence the characteristics of the product.
If more applicable or accurate data are available, they should be substituted. Other, more suitable test procedures should be used for this purpose. D Terminology of Packaging and Distribution Environments. Test duration, random spectrum, and damage criteria are to be specified by the user. 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 use.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Active view current version of standard. The determination of astj 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. Two alternate test methods are presented:. A stroboscope or video system may be beneficial for visual examination of the specimen under test. Parts and surfaces of the specimen may be marked for identification and reference. Two alternate test methods are presented: 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. This may become necessary if the response of a product would require design of an impractical or excessively costly shipping container.
No other units of measurement are included in this standard. Sensor s may be applied as appropriate to measure data points of interest with the minimum possible alteration of the test specimen. This time is dependent upon the characteristics of awtm vibration test machine and control system, the setup, and the weight and characteristics of the test specimen.
Significance and Use 4.

Historical Version s – view previous versions of standard. This may become necessary if the response of a product asym require design of an impractical or excessively costly 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.
