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.

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

ASTM D4728 updated to version 2017

Resonance astm d4728 during random vibration tests are less intense than during sinusoidal resonance dwell or sweep tests. Random vibration tests may be simultaneously astm d4728 with transient or periodic data to simulate known stresses of this type, that is, rail joints, pot holes, etc. 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 its astm d4728 packing and means of closure in terms of its ruggedness and the protection that it provides the contents when subjected to random vibration inputs. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Historical Version s – view previous versions astm d4728 standard. Random vibration may be conducted in any axis vertical or horizontal or in any package orientation. This test allows analysis of the interaction between these components.

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

However, different test levels may be utilized for each axis depending on the field environment that is astm d4728 be simulated. In this way, ASTM-D standard test method for random vibration testing of shipping containers simultaneously excite many product astm d4728 container resonances.

In this way, many product and container resonances are simultaneously excited. Therefore, unrealistic fatigue damage due to resonance buildup is asfm.

When possible, confidence levels may be improved by comparing laboratory test results astm d4728 actual field shipment effects. Equivalent tests between sine and random, in a general sense, are difficult to establish due to nonlinearities, damping and product response characteristics. Refer to Practice D for recommended astm d4728 vibration tests. Design modification to one or all of these components may be used to achieve optimum astm d4728 in the shipping environment.

However, different test levels may be utilized for each axis depending on the field environment that is to be simulated. Design modification to one or all of these components may be used to achieve optimum performance in the shipping environment.

It is the responsibility astm d4728 the user of this standard to establish appropriate safety, health s4728 environmental practices and determine the applicability of regulatory limitations prior to use. This test allows analysis of the interaction between these components.

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

Specific safety hazard statements are given in Section 6. Such tests may be used to assess the performance of a container with its interior packing and asgm of closure in astm d4728 of its astm d4728 and the protection that it provides the contents when subjected to random vibration inputs.
