Formats of Sheets

The format of the drawing sheet is called the format of this drawing’s copy after being cut in accordance with PN-76/N-01601. The basic format of the sheet is A4 with the measurements after being cut 210 x 297 mm. The formats A3, A2, A1 and A0 are derived from the multiplication of the A4 format, while the formats A5 and A6 are derived by dividing it into two and four equal parts (Fig. 5.1). All formats marked by the letter A are basic formats. In addition to them, formats can also be used which are created by multiplying the shorter sides of the basic formats in accordance with Table 5.2.

Marking the derivative format consists of marking the basic format, the digit indicating the multiplexing of the shorter side of the basic format, e. g. A3 x 7. Border deviations of sides are accepted for both basic and derivative formats, which do not exceed the values shown in Table 5.3.

Table 5.3 Border deviations of dimensions of sides of formats

Sheets before cutting, that is in a state in which they are attached to the tablet or placed in the plotter, before realisation of the drawing, should have cutting lines marked, which limit the surface of the sheet after cutting (Fig. 5.2). At a distance of 5 mm from the cutting line, the sheet should have a border limiting the surface of the sheet for the drawing and title block.
