Aluminium and aluminium alloys - Extruded rod/bar, tube and profiles - Part 7: Seamless tubes, tolerances on dimensions and form
N EN 755-7
Annotation
This European Standard specifies the tolerances on dimensions and form for aluminium and aluminium alloy extruded seamless tubes with an outside diameter (OD) from 8 mm to 450 mm (round tube, see Figure 1) or with a cross section contained within a circumscribing circle (CD) from 10 mm to 350 mm (other than round tube, see Figure 2), supplied in straight lengths.
This European Standard only applies to tube produced by the seamless die/mandrel method of extrusion. This standard applies to extruded seamless tube for general engineering applications only.
The temper designations used in this part are according to EN 515.
This European Standard does not apply to:
— extruded tubes produced by porthole/bridge method (EN 755-8),
— tubes delivered in coils (EN 13957),
— coiled tubes cut to length (EN 13957).

Алюминиевые и алюминиевые сплавы - Экструдированный шнур / брусок, труба и профили - Часть 7: Бесшовные трубы, допуски на размерах и форме
Этот европейский стандарт определяет допуски на размерах, и форма для алюминиевого и алюминиевого сплава вытеснила бесшовные трубы с внешним диаметром (OD) от 8 мм до 450 мм (круглая труба, посмотрите рисунок 1) или с поперечным срезом, содержавшим в кругу ограничения (CD) от 10 мм до 350 мм (кроме круглой трубы, посмотрите рисунок 2), поставляемый в прямых длинах.
