performance standards
Standards that measure the performance of a
product as a unit, e.g., a binding, but which do
not specify materials and methods of manufacture.
Performance standards, at least as related to

they measure the durability of the binding in the
short run only, while the need for the book, and
therefore its binding, may extend well into the
long run. period binding. See: CONTEMPORARY BINDING
