DIN ISO 2971-2015卷烟和过滤嘴.公称直径的测定.使用激非接触式光学测量仪器的方法(ISO 2971-2013)

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 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.

BS EN 71-10-2005玩具安全.有机化学化合物.样品制备和抽样

This Part 10 of the European Standard EN 71 for safety of toys specifies sample preparation and extraction procedures for establishing the release or content of organic compounds from those toys for which requirements exist in EN 71-9.
