ASHRAE Publishes Method of Test for Conformance to BACnet

New tests and test improvements are included in the newly published ANSI/ASHRAE Standard 135.1-2013, Method of Test for Conformance to BACnet.

The standard was published recently by ASHRAE. The standard defines a standard method for verifying that an implementation of the BACnet protocol provides each capability claimed in its Protocol Implementation Conformance Statement (PICS) in conformance with Standard 135, BACnet—A Data Communication Protocol for Building Automation and Control Networks.

Standard 135.1 provides a comprehensive set of procedures for verifying the correct implementation of each claimed capability, including BACnet services (as initiators, executors or both), BACnet object-types (including both required properties and optional properties), the BACnet network layer protocol, data link options and all special functionalities.

The newly published standard includes new tests for new extensions to the BACnet standard; numerous test improvements developed in cooperation with the BACnet Testing Laboratories; and references the latest version of Standard 135, published in 2012, according to Carl Neilson, chair of the Standard 135 and Standard 135.1 Committees.

“The new tests are significant and wide sweeping across the standard,” he said. “The new tests cover new functionality that has been added to the BACnet standard over the past six to 10 years. We are continuing to work on advancing the test standard to ensure it continues to have coverage as the BACnet standard is extended / maintained.”

The cost of ANSI/ASHRAE Standard 135.1-2013, Method of Test for Conformance to BACnet, is $119 ($101, ASHRAE members). To order, contact ASHRAE Customer Contact Center at 1-800-527-4723 (United States and Canada) or 404-636-8400 (worldwide), fax 678-539-2129, or visit ASHRAE’s bookstore.
