ASTM D1294-05 1英寸(25.4毫米)规准长度羊毛纤维束的拉伸强度和断裂强度的标准试验方法

Test Method D 1294 for the determination of tensile strength may be used for the acceptance testing of commercial shipments of wool, but caution is advised since technicians may fail to get good agreement between results. Comparative tests as directed in 5.1.1 may be advisable. 5.1.1 If there are differences of practical significance between reported test results for two laboratories (or more), comparative test should be performed to determine if there is a statistical bias between them, using competent statistical assistance. As a minimum, use the samples for such a comparative test that are as homogenous as possible, drawn from the same lot of material as the samples that resulted in disparate results during initial testing and randomly assigned in equal numbers to each laboratory. The test results from the laboratories involved should be compared using a statistical test for unpaired data, a probability level chosen prior to the testing series. If bias is found, either its cause must be found and corrected, or future test results for that material must be adjusted in consideration of the known bias. This test method is useful in studying the relationship between fiber strength and product quality; results should be considered comparative rather than fundamental since the strength found will be lower than the sum of the strengths of the individual fibers present due to slight differences in tensioning. Elongation may be obtained also but the accuracy of elongation measurements is limited and their determination is, therefore, not included as a formal part of this test method. The basic differences between the procedures employed in this test method and those of Test Method D 2524 are in the gage lengths employed and the methods of clamping. In Test Method D 2524, specific clamps are required whereas in Test Method D 1294, any conventional clamps may be used. Results for breaking load determined by Test Method D 2524 average 30 % higher than those obtained by Test Method D 1294.1.1 This test method covers the determination of the breaking force (or load) and estimation of the tensile strength and tenacity of wool fiber bundles with a 1-in. (25.4-mm) gage length. A procedure for preparation of the fiber bundle is included.1.2 The values stated in inch-pound units are to be regarded as standard; the values in SI units are provided for information only. Because the instrument is calibrated in inch-pound units, inch-pound units are shown first, contrary to Committee D13 policy. Note 1--For other methods of measuring breaking tenacity of fiber bundles, refer to Test Methods D1445 and D2524.Note 2--This test method can be used for other fibers that lend themselves to the same kind of preparation but the difference in density must be taken into account when calculating the tensile strength. It is not necessary to know or correct for the density of a fiber when calculating breaking tenacity.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibiltiy of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Standard Test Method for Tensile Strength and Breaking Tenacity of Wool Fiber Bundles 1-in. (25.4-mm) Gage Length

ASTM D1283-05 羊毛碱溶性的标准试验方法

Alkali-solubility is an indication of the degree of damage to wool resulting from certain chemical treatments, particularly when test results on the same wool, before such treatment, are available. 5.1.1 Undamaged scoured wool has typical alkali-solubility in the range of 9 to 15 %. Fine, undamaged wool normally will exhibit higher solubility than coarse wool, because of greater surface area per unit mass of fiber. This test method is not recommended for use on wool known to have sustained alkali damage. 5.2.1 Alkali-damaged wool has had material solubilized that ordinarily would be included in the alkali-solubility test results. Although results in one laboratory cannot usually be verified in another laboratory, this test method is considered satisfactory for acceptance testing because it has been used extensively in the trade for this purpose and because it is the only available method for assessing damage to wool by an alkali solubility procedure. Comparative tests as directed in 5.3.1 are advisable before Test Method D 1283 is used for acceptance testing. 5.3.1 In case of a dispute arising from differences in reported test results when using Test Method D 1283 for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties should take a group of test specimens which are as homogeneous as possible and which are from a lot of material of the type in question. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. The average result from the two laboratories should be compared using Studentrsquo;t-test for unpaired data and an acceptable probability level chosen by the two parties before testing is begun. If a bias is found, either its cause must be found and corrected or the purchaser and the supplier must agree to interpret future test results in the light of the known bias.1.1 This test method covers a chemical procedure for determination of the amount of wool substance soluble in alkali under standard conditions and is applicable to wool in scoured fiber form, or as fiber obtained from yarn or from woven or nonwoven fabric.1.2 The values stated in inch-pound are to be regarded as standard. The values stated in SI units are provided for information only. This test method is applicable to other animal fibers although the level of alkali-solubility may be different from wool. With individual animal fibers, undamaged solubility should be determined before attempting to assess damage on an unknown sample.1.3 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.

Standard Test Method for Alkali-Soluability of Wools

ASTM D2118-05 羊毛及其制品中标准商业公定含水量确定的标准实施规程

The purpose of this practice is to bring about uniformity of commercial moisture standards in all ASTM specifications relating to wool and its products. This practice provides a recommended single value for a standardized commercial moisture content for wool and its products. This avoids difficulties encountered in calculating the amount of moisture-free fiber present in a given mass of wool in any one of the forms listed in 1.1.1 to 1.1.8 due to trade practices which recognize various commercial moisture allowance values used by certain segments of the trade. (See Test Method D 584, Section 3.5, Table D1909, Note E, and the Tables in Practice D 2720). The recommended commercial moisture content should be used where it is desirable to avoid problems in determining moisture-free fiber content when the form of the wool is changed. For example: from scoured wool (12.0 % moisture content) to worsted yarn, dry spun (13.04 % moisture content).1.1 This practice recommends that a single value be adopted for the commercial moisture content of wool in any of the following forms:1.1.1 Scoured,1.1.2 Carbonized and neutralized,1.1.3 Noils, uncarbonized,1.1.4 Top, oil or dry combed,1.1.5 Yarn, worsted,1.1.6 Yarn, woolen,1.1.7 Yarn, hand knitting, or1.1.8 Fabric.1.2 LimitationsGrease wool, pulled wool, and wool with pH below 5.0 are excluded from this practice.This standard does not purport to address 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.

1.1 This test method covers the estimation of the average fiber diameter of wool fibers by use of the Port-Ar and the WIRA Fiber Fineness Meter instrument, which operate on the air-flow principle. Other air-flow instruments have not been tested with this method. The method is directly applicable to non-medullated, carded wool and wool top.1.2 This test method is applicable to grease wool and scoured wool after the samples of such materials have been prepared as directed in Test Method D 2130. Note 1The use of the Micronaire instrument for measuring the fineness of cotton fibers is covered in Test Method D 1448.The assignment of grade for wool and mohair is covered in Specifications D 3991 and D 3992.

This test method is not recommended for the acceptance testing of commercial shipments of wool top, card sliver, or scoured wool since the referee method, Test Method D 2130, is recommended for that purpose. Although this test method is not recommended for acceptance testing, it is useful for fast quality control checks. .If there are differences of practical significance between reported test results for two laboratories (or more), comparative test should be performed to determine if there is a statistical bias between them, using competent statistical assistance. As a minimum, use the samples for such a comparative test that are as homogenous as possible, drawn from the same lot of material as the samples that resulted in disparate results during initial testing and randomly assigned in equal numbers to each laboratory. The test results from the laboratories involved should be compared using a statistical test for unpaired data, a probability level chosen prior to the testing series. If bias is found, either its cause must be found and corrected, or future test results for that material must be adjusted in consideration of the known bias. The specific area of the wool fibers is measured by the resistance in air flow. The resistance to air flow has been related to average fiber diameter measured by the microprojection method. The instruments have been calibrated to read average diameter in micrometres. Although the reading is affected by the average fiber diameter distribution of the specimen, the results secured by the instruments give no indication of this distribution. However, in converting the micrometres reading to millitex units (Annex A1), low, medium, and high standard deviations were used in the calculations to arrive at the range of millitex units which accordingly reflect the distribution of fiber diameters. 1) Balance Adjustment Knob 8) Porosity Calibration Control 2) Balance Pan 9) Compression Lever 3) Air Reservoir10) Calibrator Plug Plunger 4) Meter Zero Adjustment Screw11) Porosity Calibrator Plug 5) Porosity Test Chamber Lid12) Calibration Weight 6) Differential Pressure Gage13) Weighing Balance Mechanism 7) Porosity Zero Control14) Atomizer Bulb

ASTM D4510-05(2009) 计算羊毛和其他动物纤维部分分裂的标准试验方法

Test Method D4510 for the counting of partial cleavages, may be used for the acceptance testing of commercial shipments of wool and other animal fibers, but caution is advised, since information on between-laboratory precision is limited. Comparative tests as directed in 5.1.1 may be advisable. In case of a dispute arising from differences in reported test results when using this test method for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties should take a group of test specimens that are as homogeneous as possible and that are from a lot of material of the type in question. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using Students t-test for unpaired data and an acceptable probability level chosen by the two parties before the testing is begun. If a bias is found, either its cause must be found and corrected or the purchaser and the supplier must agree to interpret future test results in the light of the known bias. Chemically damaged or tendered fibers are recognizable microscopically by qualified operators and should not be counted as partial cleavages. Such fibers exhibit total loss of cuticle, severe surface erosion, tenderizing cracks, longitudinal fibrillation, or a combination of these features (see Figs. 1 and 2). In a study of deliberately over-carbonized wool at one laboratory, it was found that when more than 24 tendered fibers were seen in 1 m, partial cleavage counts were significantly higher than on similar fibers that were not overcarbonized. FIG. 1 (A) Partial Cleavage—But do not count if it is at the end of a fiber.

Standard Test Method for Alkali-Solubility of Wools

ASTM D1574-04(2013) 羊毛和其它动物纤维中可萃取物的标准试验方法

5.1 Test Method D1574 is considered satisfactory for acceptance testing since the method has been used extensively in the trade for acceptance testing. 5.1.1 In case of a dispute arising from differences in reported test results when using Test Method D1574 for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties should take a group of test specimens that are as homogeneous as possible and that are from a lot of material of the type in question. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using Student's t-test for unpaired data and an acceptable probability level chosen by the two parties before the testing is begun. If a bias is found, either its cause must be found and corrected or the purchaser and the supplier must agree to interpret future test results in the light of the known bias. 5.2 This test method may be used to estimate the quantity of oil, grease, and waxy materials remaining on or in wool fibers after scouring, or the quantity of lubricant added before carding or remaining after carding, or the quantity of such materials added or removed in subsequent processing operations. 5.3 The residues obtained in this test may be subjected to chemical analysis for identification and assay of the component materials, if desired. 5.4 The specified solvent in this test method does not remove some materials, such as soaps, that may be present in wool and hence in some cases may reflect more closely the added content of some extractables in wool such as oils. When such materials are present and an estimate of their quantity is desired, some other solvent or combination of solvents should be used as specified in a material specification or by agreement. The information in the Annex of this test method may be useful for this purpose. Various solvents have been used in the past, and are still used to some extent. Many of these solvents are undesirable, however, because of flammability, toxic or anesthetic effects, or unpleasant odors. Trichlorotrifluoroethane is nonflammable, has a very low level of toxicity, and a high degree of stability and is a good solvent for most fatty or mineral oils, greases, and waxes. The specified solvent, under conditions of the test, was found in interlaboratory test not to extract wool protein.Note 2—Since the specified solvent is primarily a solvent for oils rather than soap, the extractable matter obtained in this procedure may be considered a measure of commercial oil content. Note 3—Due to the hazardous nature of some of the solvents listed in Table A1.1, the user should refer to the manufacturer's recommendations for use before using under the conditions of this test method. 1.1 This ......
