- ISO 217
The ISO 217:1995 standard defines the RA and SRA paper formats.
These paper series are untrimmed raw paper. RA stands for “raw format A” and SRA stands for “supplementary raw format A”. The RA and SRA formats are slightly larger than the corresponding A series formats. These paper sheets will after printing and binding be cut to match the A format.
* The ISO A0 format has an area of 1.00 m²
* The ISO RA0 format has an area of 1.05 m²
* The ISO SRA0 format has an area of 1.15 m²Tolerances
Paper in the RA and SRA series format has a aspect ratio but the dimensions of the start format have been rounded to whole centimetres.
