标准简介

适用范围：

1.1 This practice includes, in Table 1, the commercial composition corresponding to different commercial designations for scoured wool, wool top, and wool noil, all of which contain, in addition to wool base, various percentages of moisture, material extractable with alcohol, and mineral matter.1.2 This practice includes directions for the calculation of the commercial weight of wool corresponding to different commercial designations for several forms of wool, and for converting the commercial weight (mass) calculated on one basis to the commercial weight calculated on a different basis.1.3 This practice also includes directions for calculating the yield, on various commercial designation bases, obtained by processing raw wool, and for converting the yield calculated on one commercial designation basis to the yield on another commercial designation basis.Note 1—Because of trade practice the term “weight” is used in this practice instead of the technically correct term “mass”.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.TABLE 1 Commercial Composition of CommerciallyDesignated Scoured Wool, Wool Top, and Wool Noil PercentageWool Base Moisture Other Compo-nentsASTM Clean Wool Fiber PresentA 86.0000 12.0000 2.0000U.S. Customs Absolute Clean ContentB 86.0000 12.0000 2.0000IWTO Clean Wool ContentC 83.5299 14.5299 1.9402American Oil Combed TopD ,E 82.4222 13.0435 4.5343American Oil Combed NoilD ,E 83.4113 12.0000 4.5887American Dry Combed TopD ,E 84.1454 13.0435 2.8111American Dry Combed NoilD ,E 85.1552 12.0000 2.8448Bradford Oil Combed TopD ,E 79.2980 15.9664 4.7356Bradford Oil Combed NoilD ,E 82.7760 12.2807 4.9433Bradford Dry Combed TopD ,E 82.6449 15.4334 1.9217Bradford Dry Combed NoilD ,E 85.7260 12.2807 1.9933IWTO Noble Oil Combed TopC 79.2995 15.9664 4.7341IWTO Noble Oil Combed NoilC 82.7775 12.2807 4.9418IWTO Noble Dry Combed TopC 82.6469 15.4334 1.9197IWTO Noble Dry Combed NoilC 85.7281 12.2807 1.9912Schlumberger Oil Combed TopC 79.2995 15.9664 4.7341Schlumberger Oil Combed NoilC 81.3503 13.7931 4.8566Schlumberger Dry Combed TopC 82.6469 15.4334 1.9197Schlumberger Dry Combed NoilC 84.2500 13.7931 1.9569A ASTM Method D584, Test for Wool Content of Raw Wool, Laboratory Scale.B Tariff Schedules of the United States of America (1975), Schedule 3, Part 1, Subpart C, Headnote 1(c).C IWTO Core Test Regulations, 1974, International Wool Textile Organization.D Circular No. 3267, Nov. 10, 1954, Boston Wool Trade Assn.E Circular No. 4899, Nov. 2, 1967, Boston Wool Trade Assn.
