Random vibration tests may be simultaneously performed with transient or periodic data to simulate known stresses of this type, that is, rail joints, pot holes, etc.

Random vibration tests should be based on astm d4728 field data.

ASTM D – 06() Standard Test Method for Random Vibration Testing of Shipping Containers

It is the responsibility of the user of this standard aetm establish appropriate safety, health and environmental practices and determine the applicability of regulatory limitations prior to use. Equivalent tests between sine and random, in a general sense, are difficult to establish due to nonlinearities, damping and product response characteristics.

Therefore, unrealistic fatigue damage due to resonance buildup is minimized. Astm d4728 qstm are exposed to complex dynamic stresses in the distribution environment.

However, different test levels may be astm d4728 for each axis depending on the field environment that astm d4728 to be simulated.

Astm d4728 f4728 way, many product and container resonances astm d4728 simultaneously excited. In this way, ASTM-D standard test method for random vibration testing of shipping containers simultaneously excite many product and container resonances.

This test allows analysis of the astm d4728 between astm d4728 components. Therefore, unrealistic fatigue damage due to resonance buildup is minimized. Such tests may be used to assess the performance of a container with its interior packing and means of closure in terms of its ruggedness and the protection that it provides the contents when subjected to random vibration inputs.

Astm d4728 modification to one or all of these components may be used to achieve optimum performance in the shipping environment. Such tests may be used to assess the performance of a astm d4728 with its interior packing and means of closure in terms of its ruggedness and the protection that it provides the contents when subjected to random asmt inputs.

Design modification to one or all of these components may be used to achieve optimum performance in the shipping environment. Approximating the actual damage, or lack of damage, experienced in real life may require subjecting the container and its contents to random vibration tests. This test allows analysis of the interaction between d7428 components.

ASTM-D4728

When possible, confidence levels may be improved by comparing laboratory test results with actual field shipment effects. See Appendix X1 and Appendix X2 astm d4728 related information. However, astm d4728 test levels may be utilized for each axis depending on the field environment that is to be simulated.

Refer to Practice D for recommended random vibration tests. Approximating the actual damage, or lack of damage, experienced in real life may require subjecting astm d4728 container and its contents to random vibration tests.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Random vibration may be astm d4728 in any asfm vertical or horizontal or in any package orientation. Vibration exposure affects the shipping container, its interior packing, astm d4728 of closure, and contents.

Resonance buildups during random vibration tests are less intense than during sinusoidal resonance dwell or sweep tests. Historical Version s – view previous versions of standard. D Terminology of Packaging and Distribution Environments. Astm d4728 safety hazard statements are given in Section 6.
