ASHRAE recently announced the publication of ANSI/ASHRAE Standard 135.1-2013, Method of Test for Conformance to BACnet.

Standard 135.1 provides a comprehensive set of procedures for verifying the implementation of capabilities, including BACnet services (as initiators, executors, or both), BACnet object types (including required properties and optional properties), the BACnet network-layer protocol, data-link options, and all special functionalities, in accordance with ANSI/ASHRAE Standard 135, BACnet – A Data Communication Protocol for Building Automation and Control Networks.

The newly published standard includes tests for new extensions to the BACnet standard and numerous test improvements developed in cooperation with BACnet Testing Laboratories. Also, it references the latest version of Standard 135, published in 2012.

“The new tests are significant and wide-sweeping across the standard,” Carl Neilson, chair of the Standard 135 and Standard 135.1 committees, said. “The new tests cover new functionality that has been added to the BACnet standard over the past six to 10 years.”
