The location of the title block for sizes A0 to A3 is situated in the bottom right hand corner of the drawing space. Only sheets positioned horiz
31、ontally are permitted for these formats (see Figure 1). For size A4, sheets positioned both horizontally and vertically are permitted; the title block is situated in the bottom part of the drawing space (see Figure 1 and Figure 2).

These marks are placed at the ends of the two axes of symmetry of the trimmed sheet w
33、ith a symmetry tolerance of 1 mm. The form of the centring marks may be chosen freely. It is recommended to indicate them by continuous lines of 0,7 mm width, starting at the grid reference border and extending 10 mm beyond the drawing frame (see Figure 5). Sizes greater than A0 require additional c

35、pital letters (I and O shall not be used) and from left to right with numerals figuring on both sides of the sheet. For the size A4, they are located only at the top and the right side. The size of letters and characters is 3,5 mm. The length of the fields is 50 mm, starting at the axes of symmetry
36、of the trimmed size (centring marks). The number of fields depends on the size (see Table 2). The differences resulting from the division are added to the fields at the corners.The letters and numerals shall be placed in the grid reference border, and are to be written in vertical characters accordi
