ISO 10303-44:2000 PDF

This part of ISO 10303 specifies the resource constructs to manage the structure and configuration of a product during its life cycle.

The following are within the scope of this part of ISO 10303:

• the relationships among the components and assemblies of products;
• the relationships among products and their components as made by modification of other products;

EXAMPLE 1 The machining of a product from another product is an example of a modification.

• the description of a product as defined by customer needs;
• the dependencies among specifications of a product in order to represent possible product variations to present to a customer;
• the management of the structure for configuration of assemblies and components as planned for manufacture;
• the decomposition of a product to support different product life cycle activities;

EXAMPLE 2 An organization maintains one bill-of-material structure for a product that enumerates the quantity of each component used in each assembly, and a second bill-of-material that decomposes a product with multiple assemblies into the individual components. See annex E for more examples of different product structure reports that are supported.

• multiple versions of a single product that are equivalent with respect to form, fit, and function.

The following are outside the scope of this part of ISO 10303:

• the relationships among different product definitions for the same product;

EXAMPLE 3 The relationship of a product definition for a component in a preliminary design to a corresponding product definition for the same component in a detailed design is an example of this type of relationship.

• administrative activities of the product life cycle including approvals, security classifications, contractual arrangements, and supplier organizations;
• the change process for a product, including the reason for change and what aspect of a product has changed;
• the decisions made, and their reasons, during the product life cycle;
• the physical connections among components of a product;
• the properties that a product constituent may have;
• multiple versions of a single product that are not form, fit, and function equivalent.
