Rackstuds™ are subject to rigorous independent testing by SGS (http://www.sgs.co.nz/en/Service-by-Type-Path/Certification.aspx) Labs in Auckland.
We commissioned two test rounds.
1. During the prototyping phase.
2. Once the production tooling was complete.
We performed three tests to measure the tensile strength of a single Rackstuds:
1. Push-In Test
3. Shear Test
RACKSTUDS™️ TEST RESULTS
We performed Vibration testing with Underwriter Laboratories - to Specification MIL-STD-810G specification Method 514.6 Proc 1 “Truck transportation over US highways”. This highlighted the extreme forces that could impact the Rackstuds (or cage nuts for that matter) if you transport your 19” rack while populated and without rear support for deep equipment (>300mm/11”).
Under vibration in the x-axis, the bottom studs failed not long into the punishing one-hour test. We have a YouTube Video that shows the resonance set up in the rack when it’s vibrated with equipment installed. You will note the aluminum colored shaker table does not actually appear to be moving, but the rack and test equipment was vibrating significantly. We inspected the rack after making the video and noted that the vertical rail had cracked around the bottom right cage nut.
Vibration Testing Conclusion
We are not able to certify Rackstuds for use in applications where the equipment rack requires transportation when populated. Please read our Disclaimer below.
