Describes 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.

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 AnnexD.
NOTE 2 Alternative contact or pneumatic methods may be used but should be considered as secondary methods and do not come within the scope of the standard. These alternative measurement techniques are discussed in AnnexE.
