21、pply.3.1monitor test piecesample produced for a specific test purpose, validated to fulfil requirements within specified tolerances and intended to be used for laboratory purposes only and labelled to clearly indicate that it is not for human useNote 1 to entry: A monitor test piece is a sample take
22、n from a batch of cigarettes that show the greatest homogeneity with regard to their physical, chemical and smoke yield characteristics.3.2analysis valueresult, based on the testing of 5 or 20 items (depending on the type of smoking machine used), of a smoking test and analysis carried out in accord
23、ance with ISO 4387, ISO 8454, ISO 10315 and ISO 10362-1 (or ISO 10362-2)6DIN ISO 16055:2015-12 4 Requirements4.1 The monitor test pieces shall be produced from one production batch.4.2 The number of monitor test pieces produced shall be sufficient to cover the needs of a period of at least two years
24、.4.3 For reasons of homogeneity, the cut tobacco used shall be taken from one well-mixed batch (if possible, it is advisable to use a single grade of tobacco with no addition of further materials, such as stems, humectants or flavours, to avoid unnecessary heterogeneity of the blend).4.4 The non-tob
25、acco materials used, such as cigarette paper and filters, shall be taken from one production batch and strict quality-control measures shall be applied during the production of the filters.Recommended specifications for the production of the monitor test piece are to be found in Annex B.The requirem
26、ents shall now include a stable yield for carbon monoxide which is best obtained with a non-ventilated filter. Therefore the recommendation is that the monitor test piece is unventilated.If it is necessary to use humectants for the tobacco only glycerol is allowed. Propylene glycol cannot be used du
27、e to its high vapour pressure, which may lead to uncontrolled (undetected) loss of mass during conditioning.4.5 The production tolerances on tobacco mass, circumference and draw resistance of the monitor test piece shall be controlled as precisely as possible. It will normally be necessary to increa
28、se the quality-control measures and to decrease the production machine speed to obtain the required consistency in physical, chemical and smoke yields of the monitor test pieces. Mass control is critical in the production of a reliable monitor test piece. Excessive mass variation contributes to unac
29、ceptable variation in smoke yields. The standard deviation of mass of individual monitor test piece must be controlled to below 16 mg.4.6 The monitor test pieces in a lot shall show consistent values for the content of nicotine-free dry particulate matter, nicotine and carbon monoxide in their smoke
30、 yields. This consistency shall be assessed by means of a comparative study of sufficient size, the size chosen depending on whether the monitor is for local or broader use (see ISO 5725-2).4.7 The packaged monitor test pieces shall be stored at a temperature below or equal to +4 C until they are to
31、 be used.NOTE Other reference standards in the tobacco field require a storage temperature below -16 C for reasons of hygiene. Normally, a storage temperature of +4 C is sufficient for monitor test pieces.4.8 The product design shall ensure that the smoke yields (nicotine-free dry particulate matter
32、, nicotine and carbon monoxide) are sufficiently high per monitor test piece (approximately 14 mg NFDPM and carbon monoxide, approximately 1,4 mg nicotine) so that the influence from a possible offset in the smoking machine settings can be distinguished from the normal variation of the smoke yields.
33、4.9 It is essential to make the monitor test piece clearly distinguishable from commercial cigarettes. The monitor test pieces shall be packed in hard boxes of 20 which should be carrying a text.EXAMPLE CORESTA approved, Monitor No. X, for non-consumer laboratory purposes only. Not a commercial prod
34、uct date of production.5 TestingTesting of the lot, including determination of the values for carbon monoxide, nicotine-free dry particulate matter and nicotine in the smoke, shall be carried out in accordance with ISO 8454, ISO 4387, 7DIN ISO 16055:2015-12 ISO 10315 and ISO 10362-1 (or ISO 10362-2)
35、 in the form of an inter-laboratory trial run in accordance with ISO 5725-2. The study shall be performed by using the butt length given in the data sheet accompanying the monitor test piece.Monitor test pieces for daily routine use may be produced by the individual company for its own purposes. How
36、ever, for the purposes of inter-laboratory comparisons or for comparison of analytical consistency between laboratories, it is advised to use monitor test pieces from a common source. At present, a monitor test piece is available from CORESTA1). The CORESTA monitor test piece is tested annually for
37、consistent smoke yields in an international comparative study in accordance with ISO 5725-2.6 Data sheet information6.1 GeneralA data sheet from the source of supply of the monitor test piece shall be included. It shall contain the information set out in 6.2 and 6.3.6.2 General production specificat
38、ionsThe specifications for length, diameter, filter length, tipping length and filter material.6.3 Analysis values from inter-laboratory testingThe results from the inter-laboratory testing of the monitor test piece, comprising: the butt length used; the type of smoking machine used; the average and
39、 standard deviation of the results for nicotine in the smoke; the average and standard deviation of the results for nicotine-free dry particulate matter; the average and standard deviation of the results for carbon monoxide in the smoke; the two-sided confidence interval for the mean values, with a
40、confidence level of 95 %.7 Use7.1 GeneralMonitor test pieces are used to monitor the stability of the analytical processes involved when using a cigarette-smoking machine for routine analyses in accordance with ISO 3308. In particular, they are used to assess whether the analytical process related t
41、o the machine-smoking of cigarettes described in ISO 3402, ISO 4387, ISO 8454, ISO 10315 and ISO 10362-1 (or ISO 10362-2) is “in statistical control” (see ISO 7870-1).NOTE 1 As monitor test pieces are produced for process-control purposes, the product design is chosen to give smoke yields which are
42、well suited to these purposes and thus may well not conform to official declaration restrictions. In this context, it should be understood that the monitor test piece is not to be regarded as a commercial cigarette.The routine use of monitor test pieces may vary from laboratory to laboratory and bet
43、ween the two commonly used types of analytical smoking machine. The general principle is to evaluate the consistency of the values of the essential parameters (such as puff number, carbon monoxide in the vapour phase, 1) Address: CORESTA, 11, rue du Quatre-Septembre, F-75002 Paris. www.coresta.org 8
44、DIN ISO 16055:2015-12 total particulate matter, nicotine and water in smoke condensate and nicotine-free dry particulate matter) by using control charts.Monitor test pieces are not to be used for calibration purposes, and the results obtained with monitor test pieces shall not be used for correcting
45、 or calculating analytical data from investigation samples.The smoke yields will normally be based upon the smoking of at least 20 monitor test pieces/cigarettes as described in ISO 4387.The smoking of 20 cigarettes will give one average result from a rotary smoking machine whereas a linear smoking
46、machine will give 4 average results from smoking 5 cigarettes in each of 4 channels. This means that the variation in the smoking process has to be determined by different methods for the two smoking machines. For the rotary machine, the variation may be determined as a “between smoke runs” variatio
47、n whereas the variation for the linear machine may be determined from the 4 individual results from the 4 channels. In other words, the process variation from the rotary smoking machine is based on “independent” single results while the variation from the linear smoking machine can be based on 4 res
48、ults from one smoke run but from 4 “independent” channels.This means that different types of control chart have to be used for the two smoking machines. The actual choice shall be made according to the actual demands and cannot be specified to fit all needs. Annex A gives advice on, and examples of,
49、 the practical use of control charts.NOTE 2 This advice is based on the statistical theory described in ISO 7870-1, ISO 7873 and ISO 8258 combined with practical experience from daily use.Figure 1 illustrates the use of monitor test pieces in routine smoking analysis.IMPORTANT When analysing the control chart, always test for assignable causes in accordance with ISO 8258 and ISO 7873.9DIN ISO 16055:2015-12 Figure 1 Flow chart for use of monitor test pieces in routine analytical smoking7.2 Pract
