适用范围：This part of ISO 10303 specifies the resource constructs for the material properties of a product and for the characterization of a numerical data value as to its uncertainty and reliability. The following are within the scope of this part of ISO 10303: — association of a material property with a product; — specification of the composition of a product in terms of the amount and type of its constituents; — specification of the set of qualitative and quantitative conditions under which a material property is valid; — characterization of a numerical data value as to its uncertainty and reliability; — specification of the representation of a material property, including properties that are measured or assigned; — the material properties of the surface of a product, including coatings. NOTE - This part of ISO 10303 may be used to describe the material properties of a first stage product, such as cast ingot; an intermediate product, such as a tube or sheet; or a final stage product requiring no further processing, such as a part pressed from a sheet. The following are outside the scope of this part of ISO 10303: — the combination and transformation of material property values; EXAMPLE 1 - A design value is determined by statistical analysis of a large number of test results whose values have been combined together. This part of ISO 10303 provides for the representation of the test results and for the representation of their combination but does not address the process of combination. — the use of material properties in the analysis of product behaviour; EXAMPLE 2 - Individual property values may be combined into matrices of coefficients for use in analysis models. — the detailed geometry of the surface modification or surface finish of a product.
