Historical Standard: Standard Tables of Conversion Factors and Equivalent Yarn Numbers Measured in Various Numbering Systems<\/h4>\n
\n

ASTM D2260<\/h4>\n

Scope<\/strong><\/p>\n

\n

1.1 These tables include (1<\/span>) a series of conversion factors required to convert the number of a yarn measured in a specific system to the equivalent number measured in various other systems (see Table 1<\/span>), and (2<\/span>) specific equivalent numbers for yarns measured in various systems (see Table 2<\/span>).<\/p>\n

\n
\n TABLE 1 Conversion Factors for Converting from One Yarn Numbering System to AnotherA<\/i><\/sup><\/b>\n <\/div>\n
\n A<\/i><\/sup>\u2009The conversion factors are based on the following relationships given in Metric Practice SI\u200910SI10: 1 yard\u2009=\u20090.9144 m, exactly, and 1 lb (avoirdupois)\u2009=\u20090.453 592 37 kg, exactly. The conversion factors in Table 1<\/span> containing fewer than six significant digits are exact values.\n <\/div>\n
\n B<\/i><\/sup>\u2009Multiples and submultiples of this basic unit may be used as a convenience to avoid large numbers or decimal fractions. For example, decitex (dtex) or tex\u2009\u00d7\u200910 is suitable for fine yarns and fibers; millitex (mtex) or tex\u2009\u00d7\u20091000 is suitable for fibers; while kilotex (ktex) or tex\/1000 is often used for ropes, cords, rovings, tops, and slivers. <\/p>\n

Examples of Table 1<\/span> use:<\/p>\n

1) The English worsted count equivalent to a cotton count of 10 is 1.5 times 10, or 15 English worsted count.<\/p>\n

2) The cotton count equivalent to 30 tex is 590.54 divided by 30, or 19.7 cotton count.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n

\n

1.2 The content is basically consistent with recommendations of the International Organization for Standardization (ISO) Standard\u20092947.<\/p>\n<\/p><\/div>\n

\n

1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.<\/p>\n<\/p><\/div>\n

\n

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/i><\/p>\n<\/p><\/div>\n
