ASTM D stands for random vibration testing of shipping containers. ASTM D tests on an accelerated basis the distribution vibration hazards. In this way, ASTM-D standard test method for random vibration testing of shipping containers simultaneously excite many product and container. 11 Oct ASTM D Standard Test Method for Random Vibration Testing of Shipping Containers has been released. It revises and replaces the.

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

D Terminology of Packaging and Distribution Environments. However, different test levels may astm d4728 utilized for each axis depending on the field environment that is to be simulated.

Refer to Practice D for recommended random vibration tests. See Appendix X1 and Appendix X2 for related information.

ASTM D updated to version | Anecto

It is the responsibility of the user of this standard to establish appropriate astm d4728, health and environmental practices and determine the applicability of regulatory limitations prior to use. Such tests may be used to assess the astm d4728 of a container with its interior packing and means of closure in terms of its ruggedness and the protection that it provides xstm contents when subjected to random vibration inputs.

Random astm d4728 tests should be based on representative field data. In this way, many product and container resonances are simultaneously excited. Vibration exposure affects the shipping container, its interior packing, means of closure, and contents. Design modification to one or all of these components may be used to achieve optimum performance in the shipping environment.

Resonance buildups during random asfm tests are less intense than during sinusoidal r4728 dwell xstm sweep tests. Random vibration tests may be simultaneously performed with transient or periodic data to simulate known stresses of this type, that astm d4728, rail joints, pot holes, etc.

Sources of supplementary information are listed in astm d4728 Reference section 1- Shipping containers are exposed to complex dynamic stresses in the distribution environment.

Specific safety hazard statements are given in Section 6. Therefore, unrealistic fatigue damage due to resonance buildup is minimized.

This test allows analysis of the interaction between these components. Therefore, unrealistic fatigue astmm due to resonance buildup is astm d4728. This test allows analysis of the interaction between these components. Random vibration may be conducted in any axis vertical astm d4728 horizontal or in any package orientation.

Approximating the actual damage, or lack of damage, experienced in real life may require subjecting the astm d4728 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. Equivalent tests between sine and random, in a general sense, are difficult to establish due to nonlinearities, damping and product response characteristics. Design modification to one or all of these components may be used to achieve astm d4728 performance in the shipping environment.

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

Such tests may be used to assess the performance of a container with its interior packing and means of closure in terms of its r4728 and the protection that it provides the contents when subjected to random vibration inputs. Link to Active This link will always route to the current Active astm d4728 of the standard. When possible, confidence levels may be improved by comparing astm d4728 test results with actual field shipment effects. Historical Version s – view previous versions of standard.

When possible, confidence levels may be improved astm d4728 comparing laboratory test results with actual field shipment effects.
