While the ANSI Webstore search is designed to be flexible enough to account for complex standards document numbers, you may get more results if you search on the "core" document number – here are some examples:
| Complete Document Number |
"Core" number (it's best to include the Publisher / SDO prefix) |
| ANSI/NEMA WC 57-2014/ICEA S-73-532-2014 | NEMA WC 57 |
| IEC 60974-6 Ed. 3.0 b:2015 | IEC 60974-6 |
| ANSI/AAMI EC12:2000 (R2015) | AAMI EC12 |
Try to broaden your search by using fewer or more general terms and also double-check your spelling
