The BACnet Testing Laboratories' Working Group (BTL-WG) has released BTL Test Package v20.0, which contains updated tests and procedures to be used by manufacturers to pre-test products for BACnet compliance, and to test devices qualifying for BTL Certification. The BTL-WG was formed by BACnet International to oversee the establishment of the BACnet conformance certification and listing program.

With this release of the BTL Test Package added, test coverage has been extended to include most functionality up through BACnet Protocol Revision 20, along with some functionality from later Protocol Revisions, including BACnet Secure Connect (135-2016 plus addenda: bd, be,bi, bk, bl, bm, bn, bp, bq and BACnet/Secure Connect addendum bj).

"Testing and Certification of products is crucial to the BACnet standard's success," stated Andy McMillan, president and managing director of BACnet International. "Interoperability is facilitated by BTL testing and that is essential to maintaining BACnet's broad utilization and user satisfaction."

With Test Package 20.0 now available, BTL testing has entered a Transition Period. Test Package 20.0 replaces Test Package 18.1.4 as the current test package. The BTL Working Group has set the Transition Period to end March 18, 2022. During the Transition Period, vendors may choose to have their product tested with either test package for those products having Protocol Revision 18 or lower. Products with Protocol Revision 19 or higher must use Test Package 20.0. Any product currently in BTL Testing will continue with Test Package 18.1.4.
