标准摘要
[中文适用范围]： 本国际标准规定了一种非接触式光学方法，用于测定具有凸曲线横截面的杆状物体（名义截面为圆形或椭圆形）的平均直径、最小直径、最大直径和椭圆度（或圆度）。该方法特别适用于卷烟和滤棒。 注 1：非接触式测量技术在附录 D 中讨论。 注 2：可以使用替代的接触式或气动方法，但应视为次要方法，且不在本标准范围内。这些替代测量技术将在附录 E 中讨论。 [外文原描述]： ISO 2971:2013 specifies a non contact, optical method of gauging for determination of the mean, minimum and maximum diameters and the ovality (or roundness) of rod-shaped objects with a nominally circular or oval cross section that is convex curvilinear. The method is applicable, in particular, to cigarettes and filter rods.
