Apparatus To Perform Push/Pull Test for Product Safety Compliance

An international safety standard for information technology equipment requires servers

to be tested for compliance to certain standards before public release. One test is for all handles/gripping features. This test is comprised of the following elements:


• Application of a force four times the weight of the unit

• Holding the pull force for 60 seconds
• Inspecting for compliance

A similar test in the standard requires a specified force to be exerted on component

enclosures for 60 seconds. The purpose of these two tests is to make sure that enclosures and handle/gripping features do not break, cause injury, or create an accessibility concern after a force is applied.

The novel contribution is a design for a tool that helps to pull on the handle/gripping feature with the desired force and hold that force for 60 seconds. The tool is also able to push on an enclosure with a desired force and hold that force for 60 seconds. The tool performs a push/pull test in any realistic direction that the user might engage, allowing testers to find the worst-case direction as required by safety agencies.

The tool is either clamped to the frame or used on a bench to perform the push/pull test. The tool has a cradle to hold various brands of force gauges. This creates greater flexibility for testers who may have different model force gauges and attachments.

As shown in Figure 1, the test fixture can be mounted to a frame using clamps at the four corners. It can also be used on a test bench for situations where the handle on the equipment under test is not accessible while installed. A force gauge is placed into a

cradle that can fit multiple sized force gauges. A locking m...
