- Brass strip thickness of 0.4−12 mm, respectively from up to -0,06 -0,12 — for tapes of normal accuracy and to -0,03 -0,09 — for tapes of higher precision (increase of width of the tape increases the tolerance);
- Brass plates with a thickness of 25 to 150 mm dimension the tolerance is -2.0 to -5.0 (with the increase of plate thickness increases the tolerance).
The length of the brass strips should correspond to that given in the following table:
