ISO 10303-45:2019 (R2025)

ISO 10303-45:2019 specifies the integrated resource constructs for Material and other engineering properties. ISO 10303-45 specifies the integrated generic resources to describe the values of the material and other engineering properties of products and the conditions in which these property values are valid. This part 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.
