Things about ASTM-C1503-01: Standard specification for silvered flat glass mirror.
1.1 This specification covers the requirements for silvered flat glass mirrors of rectangular shape supplied as cut sizes, stock sheets, or as lehr ends and to which no further processing (such as edgework or other fabrication) has been done.
