The work of preparing International Standard
12、s is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take
13、part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International St
14、andard requires approval by at least75% of the member bodies casting a vote. International Standard ISO10290 was prepared by Technical Committee ISO/TC38, Textiles, Sub-Committee SC22, Product specifications.

21、 maximum load (or force) applied to a specimen in a tensile test carried to rupture for yarns, it is preferably expressed in centinewtons 3.4 elongation at break increase in length of a specimen produced by the breaking load it is usually expressed as a percentage of the original nominal length 3.5
22、tenacity ratio of the tension to the linear density of an unstrained specimen it is usually expressed in centinewtons per tex 3.6 breaking tenacity ratio of a yarns breaking load to its linear density it is usually expressed in centinewtons per tex NOTE 1For specimens of known linear density, the br
23、eaking tenacity can be obtained directly from tensile-testing machines which can be suitable adjusted to indicate tenacity instead of breaking load. 3.7 twist number of turns about the axis of a length equal to the nominal gauge length before untwisting twist is expressed preferably in turns per met
24、re, but may also be expressed in turns per centimetre 3.8 twist factor a measure of the “twist hardness” of a yarn, calculated by multiplying the number of turns per unit length by the square root of the linear density in a direct system it is typically expressed in turns per centimetre (tex) 1/2 3.

Examples, for information only, are given in Annex A. 4.1 Yarn linear density The linear density of the yarn shall be determined in accordance with ISO2060 (seealso ISO1144). 4.2 Evenness The evenness of the yarn shall be determined, for example
27、 in accordance with ASTMD1425. 4.3 Breaking load/tenacity and elongation at break The breaking load of single strands and elongation at break shall be determined in accordance with ISO2062. 4.4 Skein breaking strength The skein breaking strength of the yarn shall be determined in accordance with ISO
28、6939. 4.5 Yarn twist The number of turns per unit length shall be determined in accordance with ISO2061. The direction for twist shall be indicated by the capital letter “S” or “Z” as specified in ISO2. 4.6 Moisture regain Moisture regain shall be determined in accordance with ISO6741-1. 5 Marking T
