ASHRAE 135.1-2019

The 2019 edition of Standard 135.1 is now available for BACnet users. It includes the tests for functionality added to Standard 135 between 2013 and 2018.

Standard 135.1 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 the BACnet standard (Standard 135). It 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.
