BACnet Testing Laboratories Working Group Releases New BTL Test Package

Latest Version 18.0 includes testing for BACnet Secure Connect

The BACnet Testing Laboratories Working Group (BTL-WG) has released BTL Test Package v18.0, which contains updated testing 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, test coverage has been extended to include most functionality contained in BACnet Protocol Revision 18, along with some functionality from later Protocol Revisions, including BACnet Secure Connect.

“Tested and listed products are crucial to the success of the BACnet standard,” stated Andy McMillan, president & managing director of BACnet International. “Advancing BTL testing ensures BACnet will remain vital, and assists in BACnet’s adoption and user satisfaction.”

With Test Package 18.0 now available, BTL testing has entered a transition period. Test Package 18.0 replaces Test Package 16.1.3 as the current test package. The BTL Working Group has set the Transition Period to end February 1, 2021. During the Transition Period, vendors may choose to have their product tested with either test package for those products having Protocol Revision 16 or lower. Products with Protocol Revision 17 or higher must use Test Package 18.0. Any product currently in BTL Testing will continue with Test Package 16.1.3.
