适用范围

This International Standard specifies a non-contact, scanning laser beam method of gauging for determination of the mean, minimum and maximum diameters and the ovality of rod-shaped objects with a circular or oval crosssection. The method is applicable, in particular, to cigarettes and filter rods. NOTE 1 Alternative tape gauge and pneumatic balancing orifice measurement techniques are still widely used in the determination of nominal diameters for cigarettes and filter rods. These alternative measurement techniques are discussed in annex C. NOTE 2 For laboratories using the circumference value instead of the diameter, the circumference value is calculated by multiplying the diameter by pi (p).
