NOTENormative references to international publications are listed in Annex ZA (normative).EN ISO 2060:1995 BSI 03-1999 3 1 Scope This International Standard specifies a method for the determination of the linear density of all types of yarn in package form, with
22、 the exception of any yarn that may be the subject of a separate International Standard 1) . It includes seven optional procedures based on different methods of conditioning and preparation (see4.1 and4.2). Since the different procedures do not give the same values, it is essential that the procedur
23、e used is agreed by all parties interested in the test results. While this method is designed solely for the determination of mass per unit length of yarn, it is frequently desirable to combine this determination with tests for strength and/or tests for commercial mass. If, in such a case, skein len
24、gths other than those specified are used, the length used, and any special corrections based on it, are subject to agreement between the interested parties. This method is applicable to a) single yarns (spun, monofilament or multifilament); b) folded (plied) yarns; c) cabled yarns. It is not applica
25、ble, except by agreement, to yarns which stretch more than0,5% when the tension, in centinewtons, per unit linear density of yarn, in tex, increases from0,5 to1,0. Such yarns may be tested under special conditions if they are accepted by all the parties interested in the test results. The method is
26、not applicable to yarns having a linear density greater than2000 tex. For such yarns, other skein lengths and special conditions of reeling may be adopted by agreement of the interested parties. 2 Normative references The following standards contain provisions which, through reference in this text,

It is expressed in tex
30、or its multiples or submultiples seeISO 1139:1973 and ISO1144:1973. 3.2 commercial moisture regain arbitrary value formally adopted as the moisture regain to be used with the oven-dry mass when calculating a) the linear density, or b) the commercial or legal mass of a shipment or lot (consignment) o
31、f any specific textile material. 3.3 commercial allowance arbitrary value equivalent to the commercial moisture regain plus an approved allowance for finish, formally adopted for use with the oven-dry mass when calculating a) the linear density, or b) the commercial or legal mass of a shipment or de
32、livery of any specific textile material. 3.4 moisture equilibrium condition reached by a sample at a closely defined temperature and relative humidity when the net difference between the amount of moisture absorbed and the amount desorbed, as indicated by a change in mass, shows no trend and becomes
33、 insignificant 1) Seealso ISO1889:1987, Textile glass Continuous filament yarns, staple fibre yarns, textured yarns and rovings (packages) Determination of linear density and ISO10120:1991, Carbon fibre Determination of linear density, which were prepared specially for the needs of textile glass tec
34、hnologies.ENISO 2060:1995 4 BSI 03-1999 3.5 moisture equilibrium for testing a textile material is in moisture equilibrium with the ambient atmosphere when it does not exchange water with this atmosphere; its mass then remains constant as long as the experiment is carried out in an unchanged atmosph
35、ere. For test purposes, moisture equilibrium is reached by absorption starting from a relatively low moisture content. Moisture equilibrium for testing is considered as having been reached when the rate of increase in mass of a sample or specimen due to moisture uptake does not exceed that prescribe
36、d for the material being tested (seeISO139) 3.6 moisture-free mass 1) Constant mass of a specimen obtained by drying material at a temperature of105C 3 C in a current of dry air. 2) Amount of dry substance calculated from independent determination of moisture content, for example, distillation with
37、an immiscible solvent or titration with Karl Fischer reagent (seealso3.7). 3.7 oven-dry mass constant mass of a specimen obtained by drying in an oven under prescribed conditions of temperature and humidity NOTE 1Conditions most frequently used are a temperature of105C 3 C and an air supply having a
38、 relative humidity of65% at20C, under which conditions the specimens will not be moisture-free. 3.8 yarn package length or lengths of yarn in a form suitable for use, handling, storing or shipping. Packages may be unsupported, such as balls, skeins or cakes, or supported, such as bobbins, cops, cone
39、s, pirns, spools, tubes or beams 3.9 test skein; lea skein; numbering skein small skein which has a prescribed length of yarn and is used in this International Standard for the determination of linear density or breaking load, or both 4 Principle The linear density is calculated from the length and
40、mass of suitable specimens. Specimens of suitable length are prepared by reeling test skeins for yarn numbering under specified conditions from samples that have been adequately conditioned after suitable preconditioning in skein form. In practice, the mass of the skeins is determined under various
41、conditions, as noted in4.1.1 to4.1.3 and4.2.1 to4.2.4. Any one of the options given in4.1 and4.2 may be used if mutually agreed. 4.1 Unscoured yarn 4.1.1 Option 1: mass of the conditioned yarn at equilibrium with the standard atmosphere for testing (see11.3.1). 4.1.2 Option 2: mass of the oven-dry y
42、arn (see11.3.2). 4.1.3 Option 3: mass of the oven-dry yarn plus the commercial moisture regain (see11.3.3). 4.2 Scoured yarn 4.2.1 Option 4: mass of the scoured yarn at equilibrium with the standard atmosphere for testing (see11.4.2). 4.2.2 Option 5: mass of the scoured oven-dry yarn (see11.4.3). 4.
43、2.3 Option 6: mass of the scoured oven-dry yarn, plus the commercial moisture regain (see11.4.4). 4.2.4 Option 7: mass of the scoured oven-dry yarn, plus the commercial allowances (see11.4.5). NOTE 2The use of Option1,3 or7 is recommended. 5 Apparatus 5.1 Reel, having a perimeter such that the requi
44、red length of yarn is given by a whole number of revolutions, and with a traversing device that will avoid bunching of the yarn during reeling. A perimeter of1,000m 2,5mm is recommended. The reel shall be either a) fitted with a positive feed system at a controlled tension of0,5 0,1cN/tex, or b) fit
45、ted with an adjustable tension device. In this case, the length of the skein may be checked by some suitable means (see Annex A). Variations in the specified length of the perimeter shall be small enough that skeins prepared on the reel conform with the specifications given in Annex A. NOTE 3Existin
46、g reels with perimeters other than1m may be used if mutually agreed by the interested parties.EN ISO 2060:1995 BSI 03-1999 5 5.2 Ventilated drying oven, in which the yarn specimens are exposed at a temperature maintained at105C 3 C. The specimens shall not be subject to direct radiation from the hea
47、ting units. The oven shall be supplied with a current of predried air (less than0,01g of water per1000 l) at such a rate that the volume of air in the oven will be renewed at least once every4min. Alternatively, by agreement of all interested parties, the oven may be supplied with air at any specifi
48、ed temperature and relative humidity (R.H.). The oven shall be designed to facilitate the free passage of air through the specimens. The oven may be provided with facilities for cutting off the air current and weighing the specimens without their removal from the oven. NOTE 4Air under standard tempe
49、rature conditions (65% R.H. at20C) has a moisture vapour pressure of1515Pa. If the temperature of this air is raised to105C, the air will have a relative humidity of1,25%. Under these conditions, samples of textiles with a high moisture regain, such as regenerated cellulose or wool, may retain up to0,5% moisture. Accurate results can be secured only by suppling predried air to the oven. However, results of equal precision (but at somewhat lower levels of observed moisture content) may be obtained by suppl
