BACnet-Logo-NewUSA: 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, published this week by ASHRAE, defines a standard method for verifying that an implementation of the BACnet protocol provides each capability claimed in its protocol implementation conformance Sstatement (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 cost of ANSI/ASHRAE Standard 135.1-2013, Method of Test for Conformance to BACnet, is $119 ($101, ASHRAE members). To order, visit www.ashrae.org/bookstore.
