3. Engineering property representation A material is a product and can therefore be represented by an ISO 10303 information model for a product The value of an engineering property for a product has to be associated with a data environment (metadata) that defines its validity. ISO 10303-45: ‘Material and other engineering properties’ (1998 and 2008) Generic information model for any property of any product with its data environment Understanding (semantic) of an engineering property is defined by a measurement process ISO 10303-235: ‘Engineering properties for product design and verification’ (2009) : Information model for any property of any product measured by any process Describes an audit trail from a design value through the processes that were used to derive the value Names of processes and their properties can be defined in a reference dictionary conforming to ISO 13584 21/04/2015(c) Ferroday Ltd 2015, Vico Equense 3

4. Data dictionary for properties Principle of Part 235 is that the meaning (semantic) of an engineering property is defined by the method used to measure it. Two kinds of properties: Measured by comparison with a standard quantity (length, resistance, time, etc) Measured by simulating a behaviour (strength, fracture toughness, hardness, etc) Both need the conditions that were applicable to the value at the measurement – data environment from ISO 13030-45 Semantics of the second type require a definition of the method of measurement. An application of ISO 13584 Parts library can provide these definitions in a classification of testing methods. 21/04/2015(c) Ferroday Ltd 2015, Vico Equense 4

10. Conclusions ISO 10303-235 provides a comprehensive collection of information structures for the representation of the properties of products It is scalable for small collections of data or extendable to complex methods of measurement. Selections from a complete data set could be used for discrete parts of the supply chain but related by conformance to the same specification. Having data that is independent from proprietary software will support the re-use or remanufacture of components for sustainable development. Links with the BIM would improve the data management for components of a large construction. 21/04/2015(c) Ferroday Ltd 2015, Vico Equense 10
