Aluminium and aluminium alloys - Cold drawn rod/bar and tube - Part 8: Porthole tubes, tolerances on dimensions and form 铝和铝合金 - 冷拉棒/棒和管 - 第8部分:舷窗管 尺寸和形式的公差
发布日期: 2016-06-08
实施日期: 2016-06-08
本欧洲标准规定了外径(OD)从3 mm到350 mm(圆管,见图1)的铝和铝合金冷拉舷孔管的尺寸和形状公差,或者包含在外接圆内的横截面(CD)从8毫米到300毫米(不同于圆管,见图2),提供直线长度。 本文档仅适用于以下合金制成的一般工程应用的冷拉管: - EN AW-1050A,EN AW-1200; - EN AW-3003,EN AW-3103; - EN AW-5005,EN AW-5005A,EN AW-5049,EN AW-5251,EN AW-5052; - EN AW-6012,EN AW-6060,EN AW-6061,EN AW-6262,EN AW-6262A; - EN AW-6063,EN AW-6063A,EN AW-6065,EN AW-6082; - EN AW-7020。 本部分使用的温度指示符合EN 515。 本文件仅适用于通过舷孔/桥式方法挤出生产的管材(仅将其拉伸至最终尺寸)。 本文档不适用于: - 通过无缝模具/心轴法(EN 754-7)生产的冷拉管, - 以线圈输送的管(EN 13958), - 卷管长度(EN 13958)。 (.)
This European Standard specifies the tolerances on dimensions and form for aluminium and aluminium alloy cold drawn porthole tubes with an outside diameter (OD) from 3 mm to 350 mm (round tube, see Figure 1) or with a cross section contained within a circumscribing circle (CD) from 8 mm to 300 mm (other than round tube, see Figure 2), supplied in straight lengths. This document only applies to cold drawn tube for general engineering applications made in the following alloys: - EN AW-1050A, EN AW-1200; - EN AW-3003, EN AW-3103; - EN AW-5005, EN AW-5005A, EN AW-5049, EN AW-5251, EN AW-5052; - EN AW-6012, EN AW-6060, EN AW-6061, EN AW-6262, EN AW-6262A; - EN AW-6063, EN AW-6063A, EN AW-6065, EN AW-6082; - EN AW-7020. The temper designations used in this part are according to EN 515. This document only applies to tube produced by the porthole/bridge method of extrusion only (and then cold drawn to the final dimensions). This document does not apply to: - cold drawn tubes produced by the seamless, die/mandrel method (EN 754-7), - tubes delivered in coils (EN 13958), - coiled tubes cut to length (EN 13958). (.)
