What is BS EN 62744 - Representation of states of objects by graphical about?
BS EN 62744 is a safety standard on the representation of states of objects by graphical symbols.
BS EN 62744 provides generic rules for the representation of states of objects by graphical symbols standardized in IEC 60617, ISO 14617, IEC 60417, for example, and for future graphical symbols included in these standards.
BS EN 62744 has the purpose of:
- Ensuring the coherence of the corpus of standardization documents
- Avoiding duplication of work and contradictory requirements
BS EN 62744 provides operational states of an object as examples that typically occur and which need to be represented by standardized graphical symbols and defines generic rules to be applied. BS EN 62744 specifies which types of presentation facilities are recommended to present the different operational states to humans. BS EN 62744 is primarily intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 108.
Note 1: States concerning the several types of alarm, their classification, and management are not dealt with in BS EN 62744.
Note 2: BS EN 62744 neither define rules for the design of static graphical symbols for diagrams as provided in IEC 61082 and the ISO/IEC 81714 series nor for icons and graphical symbols for use on equipment as provided in IEC 60417, ISO 7000, and in the ISO/IEC 11581 series.
Note 3: One of the responsibilities of a technical committee is, wherever applicable, to make use of horizontal standards in the preparation of its publications. The content of BS EN 62744 will not apply unless specifically referred to or included in the relevant publications.
Note 4: BS EN 62744 does not define a list indicating which existing graphical symbols are available to be used to represent objects in their operational states following the rules established in BS EN 62744.
Who is BS EN 62744 - Representation of states of objects by graphical symbols for?
BS EN 62744 on the representation of states of objects by graphical symbols is relevant to:
- Developers and designers of graphical symbols
- Designers of HMI systems
- Technical committees and decision makers of graphical symbols
Why should you use BS EN 62744- Representation of states of objects by graphical symbols?
BS EN 62744 deals with the representation of operational states of objects by standardized graphical symbols.
BS EN 62744 establishes rules and recommendations for how objects being represented by graphical symbols can be presented with a dynamic behaviour indicating the operational states of objects occurring in practice. BS EN 62744 provides guidance for developers and designers of graphical symbols, for example in IEC 60617, ISO 14617, IEC 60417, or any other pictorial
representation of an object if being requested to consider additional forms for the presentation of operational states. BS EN 62744 also provides information relevant to designers of HMI systems, to be installed in rooms with appropriate ambient conditions (e.g., used for supervising systems).
Overall, BS EN 62744 is beneficial to users as it gives information provided by the supplier of the product to the user, containing all the necessary provisions to convey the actions to be performed for the safe and efficient use of the product.
