ISO 16484-3:2005 pdf free.Building automation and control systems (BACS)
This International Standard defines a method for creating the procurement specifications containing all essential elements required for the operational functioning of a BACS. The successful installation and operation of a BACS requires that its procurement be based on a complete specification with accurate functions.
The standard provides a template called the ‘BACS function list’ that can be found in annex A (normative). Its purpose is to determine and document the options for plant / application specific functionality. Further explanations can be given in form of plant/control descriptions, control flow chart diagrams, and plant/control schematics. Examples are given in annex B (informative). The exact specifications will be project-specific.
Information about the standardized functions is given in the form of informative examples as function-blocks,textual, and graphical descriptions in 5.5.
The normative functional descriptions within this section are provided for use by the specifier, e.g. consultant,to describe the project functionality. The descriptions in 5.5 contain no direct hardware related specifications,but the number of input and output functions help to determine the required physical or communication inputs and outputs of a BACS, the processor performance, and memory size.
NOTE For the required hardware components see Part 2 of this standard.
For each project the system programs and the plant/application specific functions are to be specified to determine the required engineering services.
The plant specific functions can be documented in plant/control schematics, control flow chart diagrams and the BACS function list, preferred as spreadsheet for further data processing, which is shown in annex A as a template.
Some complex projects and/or sophisticated control algorithms for optimal control performance require additional information and methods in order to describe the requirements clearly and completely. These additional requirements include plant and control descriptions, control flow charts, psychrometric charts, reset schedules, field device mounting instructions/illustrations.Annex B provides informative examples to indicate methods for creation of accurate documentation for a design project.ISO 16484-3 pdf free download.
