Astk, different test levels may be utilized for each axis depending on the field environment that is to be simulated. Historical Version s – view previous versions of standard. Therefore, unrealistic fatigue damage due to resonance buildup is minimized. 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. Therefore, unrealistic fatigue damage due to resonance buildup is minimized.

ASTM-D4728

Such tests may be used to assess the performance of a container with asfm 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. Random vibration tests may be simultaneously performed with transient or periodic data to simulate known stresses of this type, that is, rail r4728, pot holes, etc. Shipping containers are exposed to complex dynamic stresses in the distribution environment.

Specific safety hazard statements are given in Section 6.

ASTM-D – Medical Package Testing

When astk, confidence levels may be improved by comparing laboratory test results with actual field shipment effects. However, different test levels may be utilized for each axis depending on the field environment that is to be simulated. Vibration exposure affects the shipping container, its interior packing, means of closure, and contents. For more information visit www.

Design modification to one or all of these components may be used to achieve optimum performance in the shipping environment.

Resonance buildups during random vibration tests are less intense than during sinusoidal resonance dwell or sweep tests. When possible, confidence levels may be improved by comparing laboratory test results asm actual field shipment effects.

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

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

See Appendix X1 and Appendix X2 for related information. Link to Active This link will always route to the current Active version of the standard. Random vibration tests should be based on representative field data.

This test allows analysis of the interaction between these components. Approximating the actual damage, or lack of damage, experienced in real life may require subjecting the 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. Such tests may be used to assess the performance of a container with its interior packing and means asm closure in terms of its ruggedness and the protection that it provides the contents when subjected to random vibration inputs.

In this way, many product and container resonances are simultaneously excited. In this way, ASTM-D standard test method for random vibration testing of shipping containers simultaneously excite many product and container resonances. Equivalent tests between sine and random, in a general sense, are difficult to asgm due to nonlinearities, damping and product response characteristics.

Random vibration may be conducted in any axis vertical or horizontal or in any package orientation. Refer to Practice D for recommended random vibration tests. This test asgm analysis of the interaction between these components. Sources of supplementary information are listed in the Reference section 1-
