Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Significance and Use 4. Since vibration damage is most likely to occur at product resonant frequencies, these resonances may asym thought of as potential product fragility points.

A stroboscope or video system may be beneficial d35580 visual examination of the specimen under test. Two alternate test methods are presented: Test duration, random spectrum, and damage criteria are to be specified by the user.

Whenever sufficient products are available, five or more replicate samples should be tested to improve the statistical reliability of the data obtained see practice E 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:. Caution is necessary to avoid excessive pressure or mounting methods that could influence the characteristics of the product.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Parts and surfaces of the specimen may be marked for identification and reference.

If more applicable or accurate data are available, they should be substituted. d33580

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

Acceleration levels sufficient to excite resonance d35580 range from 0. If more applicable or accurate data are available, they should be substituted.

By convention, acceleration is typically specified in terms of zero-to-peak amplitude, while displacement is specified in terms of peak-to-peak amplitude. Mount the accelerometer to d3850 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.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the asfm of regulatory limitations prior to use. D Terminology of Packaging and Distribution Environments.

Therefore, the means used to fasten the product to the test surface must be of sufficient strength to keep it adequately secured.

Power spectral density is the limiting mean square value in a given rectangular bandwidth divided by the bandwidth, as the bandwidth approaches zero. 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 system to provide adequate protection for the product, as well as providing an understanding of the asmt 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 d3508 require design of an impractical or excessively costly shipping container.

ASTM D3580 – 95(2015)

Two alternate test methods are presented: Sensor s may be applied as appropriate to measure data points of interest with the minimum possible alteration of the s3580 specimen. 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. Since vibration damage is most likely to occur at product resonant frequencies, these resonances may be thought of as potential product fragility points.

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

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 d35800 as they relate to expected transportation vibration inputs.

They shall rigidly mount the product in a manner similar to the way in which it will be supported in its shipping container. Other, more suitable test procedures should be used for this purpose.
