Industrial automation systems and integration -- Product data representation and exchange -- Part 45: Integrated generic resource: Material and other engineering properties
ISO 10303-45:2008 specifies the integrated generic resources to describe the values of the material and other engineering properties of products, as well as the conditions in which these property values are valid. 10303-45:2008 also includes the resource constructs for describing the composition of products. Property and composition values can be identified either as a numerical value or as a mathematical function. Numeric values and values as mathematical functions can be further characterized as to their type, precision and uncertainty.
