DIN ISO 2971
Cigarettes and filter rods - Determination of nominal diameter - Method using a non-contact optical measuring apparatus (ISO 2971:2013)
Zigaretten und Filterstäbe - Bestimmung des Nenndurchmessers - Berührungsloses optisches Messverfahren (ISO 2971:2013)
Overview
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. Non-contact measurement techniques are discussed in Annex D. 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 Annex E. This document contains the German translation of the International Standard ISO 2971:2013 which has been prepared in Technical Committee ISO/TC 126 "Tobacco and tobacco products", Subcommittee SC 1 "Physical and dimensional tests" the secretariat of which is held by AFNOR (France). The responsible national body is Working Committee NA 057-04-01 AA "Tabak und Tabakerzeugnisse" ("Tobacco and tobacco products") in DIN Standards Committee Food and Agricultural Products (NAL).
