24、016 (E) DIN EN ISO 5089:2016-09 4 0 INTRODUCTION In the methods given in this International Standard, the laboratory test samples are obtained by the combination of numerous small portions each drawn from a different part of the laboratory-bulk Sample. Therefore, any results obtained on test specime
25、ns from these samples will estimate the mean level in the laboratory bulk Sample but will not indicate the variability of level from Portion to Portion of the laboratory bulk Sample. Consequently it is appropriate to use this method in cases where it is. desired to estimate the bulk composition, for
26、 example the proportions of different fibres in a blend, but it is not appropriate in cases where variability is important, for example in the determination of pH where the local value is significant, or in the determination of fungicides, where a high value in one area of the material does not comp
27、ensate for a low value elsewhere. Nor may it be appropriate .for use in determination of commercial mass values. 1 SCOPE AND FIELD OF APPLICATION This International Standard specifies methods of obtaining laboratory test samples of textile materials from Iaboratory bulk samples taken from a bulk Sou
28、rce, and gives general directions for the preparation of test specimens of convenient size for Chemical tests. No Provision for sampling from the bulk Source is described since it is assumed that the laboratory bulk Sample has been selected by a suitable procedure and is representative of the bulk S
29、ource. 2 DEFINITIONS 2.1 bulk Source : That quantity of material which is to be judged on the basis of one series of test results. This may comprise, for example, all the material in one delivery of cloth; all the cloth woven from a particular beam; a consignment of yarn; a bale or a group of bales
30、of raw fibre. 2.2 laboratory bulk sample : That Portion of the bulk Source taken to be representative of the whole. The size and nature of the laboratory bulk Sample should be sufficient to overcome adequately the variability of the bulk Source and to facilitate ease of handling in the laboratory. 2
31、.3 laboratory test Sample : That Portion of the laboratory bulk Sample from which specimens are taken for testing. The size and nature of the laboratory test Sample should be sufficient to overcome adequately the variability of the laboratory bulk Sample. 2.4 test specimen : The Portion of material
32、required to give an individual test result. 3 PRINCIPLE The laboratory test Sample is taken so that it is representative of the laboratory bulk Sample. The test specimens are taken from the laboratory test Sample in such a way that each of them is representative of the laboratory test Sample. 4 SAMP
33、LING FROM LOOSE FIBRES . 4.1 Non-oriented f ibres If the laboratory bulk Sample consists of. less than 5 kg of loose fibre, spread it out in an even layer. Obtain the laboratory test Sample by taking at random a minimum of 100 tufts of approximately equal size, the total mass sufficient to give a la
34、boratory test Sample of required size, If the laboratory bulk Sample is greater than 5 kg, divide it into a number of equal portions, and take an equal number of tufts of suitable mass from each Portion such that the total number from all portions exceeds 100. Pretreat the laboratory test Sample if
35、required by the test method to be used. From the laboratory test Sample remove at random, using forceps, small tufts of approxi- mately equal mass to give a test specimen of the mass required. 4.2 Oriented fibres (card webs, slivers, rovings) From randomly selected Parts of the laboratory bulk Sampl
36、e tut not less than ten Cross-sections each of mass approximately 1,O g. After applying pretreatment if necessary, lay the Cross-sections together and obtain the test specimen by cutting through them so as to take a Portion of each of the ten lengths.

37、 SAMPLING YARN 5.1 Yarn in packages or in hanks If the number of packages in the laboratory bulk Sample is 25 or less, Sample all the packages. If the number exceeds 25, take 25 packages at random. If the linear density of the yarn, expressed in tex, is t, and the number of packages taken from the I
38、aboratory bulk Sample is n, the length of yarn from each package to give a 10 g laboratory test Sample is IO6 ntcm If n t is high, for example more than 2 000, wind a heavier skein and tut it across in two places to make a tow of suitable mass. Withdraw the appropriate continuous lengths from each p
39、ackage either by winding skeins of the same number of turns on a wrap reell 1, or by some other means. Unite the lengths side by side either as a Single skein or as a tow to form the Iaboratory test Sample, ensuring that there arc equal lengths from each package in the skein or tow. Pre- treat the l
40、aboratory test Sample if required by a suitable method and ensure that the ends of any Sample in the ferm of tow are securely tied before treatment. Take specimens of the appropriate mass from the laboratory test Sample by cutting a bunch of threads of equal length from the skein or tow and comprisi
41、ng all the threads in it, ensuring that test specimens are taken from a place remote from the tie bands. 5.2 Yarn on warp Take the laboratory test Sample by cutting a length from the end of the Warp, not less than 20 cm long and comprising all the yarns in the warp except the selvedge yarns, which a
42、re rejected. Tie the bunch of threads together near one end. If the Sample is too large for any required pretreatment divide it into two or more portions, each tied together for pretreatment, and reunite the Pottions after the pretreatment of each separately. Take a test specimen by cutting a suitab
43、le length from the laboratory test Sample from the end remote from the tie band, and comprising all the threads in the Warp. For warp of N threads of tex t, the length of a specimen of tnass 1 g is IO5 -cm Nt 6 SAMPLING FABRIC 6.1 From a laboratory bulk Sample consisting of a Single cutting up to 1
44、m in length Cut a diagonal Strip from corner to corner and remove th.e selvedges. For a laboratory test Sample of X g the area of the Strip required is x IO4 cm* M where M is the mass of the cloth in grams per Square metre. This area divided by the length of the diagonal in centimetres will give the
45、 required width of Strip in centimetres. After subjecting the Strip to any pretreatment, tut it across its length into four equal lengths and superimpose them. Take test specimens from any part of the layered material by cutting through all the layers in such a way that each specimen comprises an eq
46、ual length from each layer. 6.2 From a laboratory bulk Sample consisting of a Single cutting more than 1 m in length Take two full-width cuttings, one from each end of the laboratory bulk Sample and not more than 1 m long. Cut both into two equal portions by a tut parallel to the warp direction and
47、mark the right-hand and left-hand halves of each. Put the right-hand half of one cutting to the left-hand half of the other, with the tut edges together, and tut a diagonal Strip from the Iower corner of one cutting to the upper corner of the other, after removing the selvedges. Proceed as in 6.1, t
48、reating the two half-width diagonal Strips as if they were a full-width continuous Strip. 6.3 From cuttings a laboratory bulk consisting of Treat each cutting separately as described in 6.1 or 6.2 and give results for each cutting in the test report. 6.4 From a fabric with a design arising from the
49、distribution of threads Ensure, if possible, that there is an integral number of complete repeats of the design in the laboratory bulk Sample and proceed as in 6.1 unless the laboratory bulk Sample so obtained is more than 1 m in length, in which case proceed as in 6.2. Where the Pattern repeat is large 1) If the packages tan be mounted in a convenient creel a number tan be wound simultaneously.
