ISO 2971

Description / Abstract: This International Standard 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.

NOTE 1 Non-contact measurement techniques are discussed in Annex D.

NOTE 2 Alternative contact within the scope of the standard. These alternative measurement techniques are discussed in Annex E.
