ISO/TS 10303-1112 specifies the application module for Specification control.

The following are within the scope of ISO/TS 10303-1112:

• product classes used to identify sets of similar products to be offered to the market;
• specifications used to describe characteristics of the products;
• specification categories used to group similar characteristics of the products;
• specification expressions used to control the usage of a part within a product and to represent conditions for product classes;
• product functions used to describe the functional requirements for products and components of products;
• product components used to describe the common decomposition structure of all products of a product class or of various alternative solutions;
• alternative solutions used to describe the variants for a product component or for a product function;
• item instances used to identify an occurrence of a component in an assembly structure;

  EXAMPLE 1   An item instance could identify the elements of an alternative solution.

• configurations used to link the parts (item instances), alternative solutions, product components, or product functions with their usage cases;

  EXAMPLE 2   An usage case is the the conditions under which configurations are used.

• product specifications are used to identify a manufacturable product out of a product class by its specific characteristics (specifications);

  EXAMPLE 3   A customer order for a piece of furniture is a product identification.
