ISO 13584-42:2010规定了用于定义零件特征分类和零件特性的原则，这些原则规定了独立于任何特定供应商定义标识的零件特征。 ISO 13584-42:2010规定: -通过限制属性的价值范围，对属性的约束进行建模的能力； -建模和区分表征类和分类类的能力； -使用单一资源机制对聚合和组合建模的能力； -描述携带外部引用的字符串的能力； -连接属于不同类层次结构的类的能力。

ISO 13584-42:2010 specifies the principles to be used for defining characterization classes of parts and properties of parts which provide for characterizing a part independently of any particular supplier-defined identification. ISO 13584-42:2010 specifies : — the capability to model constraints on properties by restricting their domain of values; — the capability to model and distinguish characterization classes and categorization classes; — the capability to model aggregation and composition using a single resource mechanism; — the capability to describe strings that carry external references; — the capability to connect classes that belong to different class hierarchies.
