A Block is a set of Properties within an Application Class describing an abstraction of a feature of the product or of a part of a composite device.
Note:
If all Properties of a device type are arranged with equal importance on one single level, the list will become less understandable while more Properties are added. Clarity can be achieved by structuring the Properties into sub-concepts, which are described by Properties. These sub-concepts are called Block (of Properties).
Every Block of Properties has a name and definition as defined in IEC 61360 Part 2 ed1 / ISO13584-42 ed1 for Properties. Blocks are structured in a similar way to Properties.A Block - in contrary to the related concept of an Aspect - describes characteristics of the product itself.
A Block of Properties consists of one or more Properties describing an abstraction of a feature of an object or of a part of a composite device.
A Block of Properties may contain other Blocks of Properties nested to the necessary level as dictated by the technical requirements. At the lowest level, a Block will contain only Properties.
