<part-type-class>
This chapter documents the use-related requirements. Since the part type of a component can be used (instantiated) several times, the use-related descriptions (i.e. specifications that deviate from part type) are documented for each part. If two or more parts of the same part type have identical use-specific definitions, then they only need to be documented once. These definitions can then be referenced for the other parts.
General product data  Concrete specifications for the operating environment, useful life, and reliability for this part are described.
