ISO 2971:2013 Cigarettes and filter rods - Determination of nominal diameter - Method using a non-contact optical measuring apparatus

standard by International Organization for Standardization, 04/01/2013

Full Description

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.
