This part of ISO 10303 specifies the application module Specification control. The following are within the scope of this part of ISO 10303:

• 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.

• items within the scope of application module Alternative solution, ISO/TS 10303-1109;
• items within the scope of application module Part collection, ISO/TS 10303-1115;
• items within the scope of application module Product placement, ISO/TS 10303-1343;
• items within the scope of application module Requirement view definition, ISO/TS 10303-1141;
