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

Specific astm d4728 f4728 statements are given in Section 6. However, different test levels may be utilized for each axis depending on the field environment that is to be simulated. This test allows analysis of the interaction between these components.

Shipping containers are exposed to complex dynamic stresses in the distribution environment. Equivalent tests between sine and random, in a general sense, are difficult to establish due to nonlinearities, damping and product astm d4728 characteristics.

Design modification to one or all of astm d4728 components may be used to achieve optimum performance in the shipping environment.

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. D Terminology of Packaging and Adtm Environments. Design modification to one or all of these components may be used astm d4728 achieve optimum performance in the shipping astm d4728.

Therefore, astm d4728 fatigue damage due to resonance buildup is minimized. This test allows analysis of astm d4728 interaction between these components. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

ASTM D4728 updated to version 2017

Refer to Practice D for recommended random vibration tests. Therefore, unrealistic fatigue damage due to resonance buildup is minimized. However, different test levels may be utilized for each axis depending on the field environment that is astm d4728 be simulated.

Random vibration tests may be astm d4728 performed with transient or periodic data to simulate known stresses of this type, that is, rail joints, pot holes, etc.

See Appendix X1 and Appendix X2 for related information. It is the responsibility of the astm d4728 of this standard to establish appropriate safety, health and environmental practices and determine the applicability of regulatory limitations prior to use.

ASTM-D4728

When possible, confidence levels may be improved by comparing laboratory test results with actual field shipment effects. Random vibration tests should be based on representative astm d4728 d47728. Random astm d4728 may be conducted in any axis vertical or horizontal or in any package orientation. Historical Version s – view previous versions of standard.
