If you have the title or number of the standard, you can search the Library catalog using a title search or a keyword search. If you have trouble, ask a librarian to help you. Try to give the librarian as much additional information as you have. For example, whether the standard is an ASME standard or any other origination information you may have.
You should also try the home page of the organization that originated the standard to see if they make in freely available over the Web.
