EN ISO 2060:1995 BSI 03-19993 1 Scope This International Standard specifies a method for the determination of the linear density of all types of yarn in p
22、ackage form, with the exception of any yarn that may be the subject of a separate International Standard1). It includes seven optional procedures based on different methods of conditioning and preparation (see 4.1 and 4.2). Since the different procedures do not give the same values, it is essential
23、that the procedure 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
24、a case, skein lengths 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.
25、It is not applicable, except by agreement, to yarns which stretch more than 0,5 % when the tension, in centinewtons, per unit linear density of yarn, in tex, increases from 0,5 to 1,0. Such yarns may be tested under special conditions if they are accepted by all the parties interested in the test re
26、sults. The method is not applicable to yarns having a linear density greater than 2 000 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 r
27、eference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying

30、arn. It is expressed in tex or its multiples or submultiples see ISO 1139:1973 and ISO 1144:1973. 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 s
31、hipment or lot (consignment) of 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
32、legal mass of a shipment or delivery 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 ma
33、ss, shows no trend and becomes insignificant 1) See also ISO 1889:1987, Textile glass Continuous filament yarns, staple fibre yarns, textured yarns and rovings (packages) Determination of linear density and ISO 10120:1991, Carbon fibre Determination of linear density, which were prepared specially f

EN ISO 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
35、carried out in an unchanged atmosphere. 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 up
36、take does not exceed that prescribed for the material being tested (see ISO 139) 3.6 moisture-free mass 1) Constant mass of a specimen obtained by drying material at a temperature of 105 C 3 C in a current of dry air. 2) Amount of dry substance calculated from independent determination of moisture c
37、ontent, for example, distillation with an immiscible solvent or titration with Karl Fischer reagent (see also 3.7). 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 temperat
38、ure of 105 C 3 C and an air supply having a relative humidity of 65 % at 20 C, 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 c
39、akes, or supported, such as bobbins, cops, cones, 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 li
40、near density is calculated from the length and 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
41、mass of the skeins is determined under various conditions, as noted in 4.1.1 to 4.1.3 and 4.2.1 to 4.2.4. Any one of the options given in 4.1 and 4.2 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 testin
42、g (see 11.3.1). 4.1.2 Option 2: mass of the oven-dry yarn (see 11.3.2). 4.1.3 Option 3: mass of the oven-dry yarn plus the commercial moisture regain (see 11.3.3). 4.2 Scoured yarn 4.2.1 Option 4: mass of the scoured yarn at equilibrium with the standard atmosphere for testing (see 11.4.2). 4.2.2 Op
43、tion 5: mass of the scoured oven-dry yarn (see 11.4.3). 4.2.3 Option 6: mass of the scoured oven-dry yarn, plus the commercial moisture regain (see 11.4.4). 4.2.4 Option 7: mass of the scoured oven-dry yarn, plus the commercial allowances (see 11.4.5).

44、d. 5 Apparatus 5.1 Reel, having a perimeter such that the required 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 of 1,000 m 2,5 mm is recommended. The reel shall be either a) fitted with a posit
45、ive feed system at a controlled tension of 0,5 0,1 cN/tex, or b) fitted 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
46、reel conform with the specifications given in Annex A. NOTE 3Existing reels with perimeters other than 1 m may be used if mutually agreed by the interested parties. EN ISO 2060:1995 BSI 03-19995 5.2 Ventilated drying oven, in which the yarn specimens are exposed at a temperature maintained at 105 C
47、3 C. The specimens shall not be subject to direct radiation from the heating units. The oven shall be supplied with a current of predried air (less than 0,01 g of water per 1 000 l) at such a rate that the volume of air in the oven will be renewed at least once every 4 min. Alternatively, by agreeme
48、nt of all interested parties, the oven may be supplied with air at any specified 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
49、 specimens without their removal from the oven. NOTE 4Air under standard temperature conditions ( 65 % R.H. at 20 C) has a moisture vapour pressure of 1 515 Pa. If the temperature of this air is raised to 105 C, the air will have a relative humidity of 1,25 %. Under these conditions, samples of textiles with a high moisture regain, such as regenerated cellulose or wool, may retain up to 0,5 % moisture. Accurate results can be secured only by suppling predried air to the oven. However, results of equal p
