If a dummy load is used, an assessment must be made, after the test is completed, as to whether or not the actual test item would have passed or failed. Sensors and transducers should be applied with minimum possible alteration of the test specimen to obtain data on the container or packaged item.

When it is necessary to observe the contents during the test, holes may be cut in noncritical areas of the container. Conditioning 9. When no conditioning requirements are given, and the container materials are climatically sensitive, a conditioning atmosphere is recommended see Practice D for standard and special conditions.

Procedure The specimen center of gravity should be as near as practicable to the center of the table. Unit loads, stacked columns, or single units should be allowed to vibrate freely unless they will actually be securely fastened during shipment, crates on a flatbed trailer for example. When the specimen is not secured to the table, restraining devices should be attached to the vibration table to prevent potential movement of the specimen off the vibration table.

To address some of the most common causes of hydraulic hose—related downtime, consider a convenient and flexible spiral wrap from M. The right hose and wrap combination can protect and extend the life of hydraulic systems in applications including agricultural machinery, industrial manufacturing, and materials handling.

The Right Materials for Your Hydraulic Hose Wrap A hydraulic hose wrap must meet certain criteria to offer value to the equipment user.

We typically recommend our PTFE spiral wrap for hydraulic hose wrap applications. Quickly and easily install our hose wraps by hand. The wrap works much like tape to conform seamlessly around bundles between one and five inches in diameter.

Our wraps even work well for temporary hose wrap applications. When the new component arrives, simply unwind the reusable wrap or work around it.

We designed our industrial wraps with real-world use cases in mind. Read more about our spiral wraps. You may see alternatives to a hydraulic hose wrap from hydraulic fittings suppliers. While a sleek sleeve may seem like a good idea, they can lead to increased downtime on the job. Sleeves may require users to run the length of the hose through the sleeve and leave the actual hose hidden from view.

Some sleeves feature Velcro connections that wear down over time.

This is important since random vibration will produce relatively large, low frequency displacements in an unpredictable sequence. This enables the closed loop control system to complete its equalization at lower test levels and provides the operator adequate opportunity to visually verify that the test specimen and? The test duration is the time at full test level.

Time spent during start up is not included.
