Sensor s may be applied as appropriate to measure data points of interest with the minimum possible alteration of the test specimen. Other, more suitable test procedures should be used for this purpose.

ASTM D3580 – 95(2015)

For sine testing, the frequency sweep may be interrupted or reversed if necessary for short time periods in order to properly identify a resonating component. Significance and Use 4. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.

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. See Section 6 for specific aastm statements. Test duration, random spectrum, and damage criteria are to be specified by the user. 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.

The test surface aztm be driven to move only in vertical linear motion throughout the desired range of amplitudes and frequencies. Other, more suitable test procedures should be used for this purpose.

Parts and surfaces of the specimen may be marked for identification and reference. The two test methods are not necessarily equivalent and may not produce the same results. Therefore, the means used to fasten the product to the test surface must be of sufficient strength to keep it adequately secured. Other, more suitable test procedures should be used for this purpose.

Starting at 3 Hz, vary the frequency of vibration at a continuous logarithmic rate of 0. Two alternate test methods xstm presented: Link to Active This link will always route to the current Active version of the standard.

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.

D Terminology of Packaging and Distribution Environments. D Terminology of Packaging and Distribution Environments. 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.

The instantaneous magnitudes of random vibration are not prescribed for any given instant satm time, but instead are prescribed by a probability distribution function, the integral of which over a asmt magnitude range will give d35800 probable percentage of the time that the magnitude will fall within that range. No other units of measurement are included in this standard. Stop the test method immediately if a dangerous condition should develop.

Acceleration levels sufficient to excite resonance normally range from 0. D35880 alternate test methods are presented:. Since vibration damage is most likely to occur at product resonant frequencies, these resonances may be thought of as potential product fragility points. Two alternate test methods are presented:. 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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. It is recommended that the minimum frequency range be from 3 to Hz, the overall amplitude d380 of the spectrum be not less than 0.

Caution is necessary to avoid excessive pressure or mounting methods that could influence the characteristics of the product. 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.

This may become necessary if the response of a product would require design of an impractical or excessively costly shipping container. If more applicable or accurate data are available, they should be substituted. Use a stroboscope; sensors and readouts; and visual, auditory, or other means as applicable to determine these resonances. Asgm sufficient products are available, five or more replicate samples should be tested to improve the statistical reliability of the data obtained see practice E Dwell time, acceleration level, and damage criteria are to be specified by the user.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations f3580 to use. They shall rigidly mount the product in a manner similar to the way in which it will be supported in its shipping container.

Link to Active This link will always route to the current Active version of the standard. Any resonances with transmissibilities of 2 or greater may be considered significant.

ASTM D – 95() Standard Test Methods for Vibration (Vertical Linear Motion) Test of Products

The mounting devices shall not have significant resonances in the test frequency range. When necessary to observe interior components of the product during tests, holes may be cut in noncritical area or noncritical panels may be removed. This may become necessary if the response of a product would require design of an impractical or excessively costly shipping container.

Record r3580 resonant responses of the product, repeat the cycle if necessary. Active view current version of standard. For spectrum examples, see This may become necessary if the response of a product would require design of an impractical or excessively costly shipping container. A stroboscope or video system may be beneficial for visual examination qstm the specimen under test.

Adjust the frequency of the aatm as necessary to maintain resonance.

By convention, acceleration is typically specified in terms of zero-to-peak amplitude, while displacement is specified in terms of peak-to-peak amplitude. If more applicable or accurate data are available, they should be substituted. 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 r3580 use.
