The ADA Ductboard™ system meets the design requirements of AS 1170.4, NZS 4219, and other international seismic codes. In addition, we have successfully tested the system in accordance with AS 60068.3.3 Environmental Testing: Guidance – Seismic Test Methods for Equipment.
Specifications
Ductboard Support Plates used in conjunction with a special MB threaded rod and CADDY® Speed Link System suspends Cushion Head Boxes for seismic applications.
We successfully tested various ADA Ductboard™ fabrications and recommended suspension methods. Testing conducted in accordance with AS 60068.3.3 Environmental Testing: Guidance – Seismic Test Methods for Equipment. This standard details the test method for seismically testing ductwork fabrications.
Testing confirmed that all configurations achieved Performance Level III under horizontal accelerations of 15 m/s² at frequencies up to 16 Hz.
Caddy Speed Link System
- ADA recommends the CADDY® Speed Link System for ductwork suspension
- Testing has confirmed that the SLK parts shown are suitable for seismic applications.
- Systems include locking device, flexible wire rope, and various specialty end fittings
- A complete range of CADDY® parts and accessories are available for other general ductwork suspension applications
Rigorous Testing
ADA Ductboard™ fabrications have been successfully tested using AS 60068.3.3 Environmental testing: Guidance – Seismic test methods for equipment. Furthermore, all configurations were tested to Performance Level Ill with horizontal accelerations of 15 m/s2 to a maximum of 16Hz.
