descriptive spec- open or closed

is descriotive spec and open spec or closed?
it gives [b][b]exact details of how to assemble a component, the materials how it should go together, physical and chemical properties. how is it open? just becuase the conc. can pick any brand of for example aluminum window siding?but if ur describing its properties and connection thats narrowing it down to a proprietary item if you have so many constrains and and connections

open, exactly because of what you wrote: "just because the conc. can pick any brand"

Descriptive spec calls out every element; chemical properties, manufacturing process, installation, look & function = descriptive.
However, if it doesn't call out the manufacturer or product number = open.
