Cheval tests the load (weight bearing) capacity of all our products. These tests are designed to help determine upper limits to the amount of weight a particular product can safely and functionally support. Most firms will provide a load rate for their product, but not many really tell you how they arrived at the figure. We have developed a series of tests to ensure your safety and our product quality and want to share some of our procedures with you.
Cheval rack load tests have two categories, static and dynamic. Static tests are conducted with the rack standing still. Dynamic tests will physically move the rack some distance while under load. Dynamic tests are also performed on the casters as well. These dynamic tests are done in a special test facility and subject the casters to a series of events including a threshold simulation test, continuous run and intermittent run. While Cheval standard casters are individually rated to 285 KG dynamic load, in practice, it may be extremely difficult for the average user to physically move a fully loaded rack. Our heavy duty casters are rated to 400 KG.
Cheval racks undergo a series of load tests and measurements. We have provided details of one of the tests, a vertical static load test. The rack shown is an Arion V2 600x1200 42U rack with 1,400 KG load equally distributed. As the weight is loaded on the rack, measurements, as indicated by these diagrams, are taken. The variance, if any, between the original dimensions and dimension of the same position after the load is noted. This discrete data is then analyzed and plotted on a graph. In order to pass this test, the rack must not only have no structural failure, but the critical dimensions shown can flex no more than 4.00 mm after loading and no effect on the function of the rack such as the bottom shelf doesn't hit bottom frame when pulled out when rack is loaded. Arion racks support static loads up to 1,400 KG. As well as following these load limits, we strongly recommend you follow best practices for load distribution when installing your equipment. For example, heavier equipment should be installed in the lower section of the rack and if you are using pull out devices, do not extend more than one device at a time. For additional safety, bolt down kits are available for all our 19" racks. Depending on the size of the rack, the load rates will vary. Please refer to the specific model for its load rate.
Data and Table Page
Table below shows the dimension of ARION V2 Rack 42U X W600 X D1200 with Static Load test. Test structure of the 19" rack was not deformed more than 4 mm after loading and bottom shelf did not hit bottom frame when pulled out. Test results = Passed
Graph shown below is the results of frame deflection test after static load. The structure of ARION V2 Rack 42U X W600 X D1200 maintained it's original dimensions. There was a very small value difference and after test pull out shelf to ensure no interference with bottom of frame. Test structure of the 19" rack was not deformed more than 4 mm after loading and bottom shelf did not hit bottom frame when pulled out. Test results = Passed.

Method of Monitoring and PASS/FAIL Criteria.
The EUT is evaluated against physical and design criteria of the IP-CHE-RACK-TEST CHE specification of Cheval's testing standard for frame deflection.
|Model||Static Load (kg)||Pass /Fail*||Effect after Test|
|Top-Bottom Frame||Vertical Frame||Side Brace||Sliding Shelf|
|ARION V2 600W 1200D 42U With Middle Side Brace||1400||Pass||Damage did not occur||Damage did not occur||Damage did not occur||Function normally, shelf did not hit bottom frame|
