dimensional with random length — КД1ГОСТ 2591-2006 Прокат сортовой стальной горячекатаный квадратный. Сортамент;

random — ND;

limited within the random — OD;

limited from the random length — EA1ГОСТ 2591-2006 Прокат сортовой стальной горячекатаный квадратный. Сортамент;

Notes

1 cross-sectional Area and weight of 1 m of length of rental is calculated based on nominal dimensions. When calculating the mass of 1 m length of the rental, the density of steel is equal to 7.85 g/cmГОСТ 2591-2006 Прокат сортовой стальной горячекатаный квадратный. Сортамент. Weight of 1 m length and cross-sectional area of hire are reference values.

2 By agreement between manufacturer and consumer (the agreed specifications) hire manufacture intermediate sizes with extreme deviation to the nearest smaller size.

2.2.1 hire with precision rolling B2 (table 1) allowed to produce with plus the marginal variance equal to the sum of the limit deviations on the side of the square (EOI).

2.3 By agreement between manufacturer and consumer (the agreed specifications) hire with plus produce extreme deviations (B4) shown in table 2.
