This standard IWTO-30-98 Technical changes compared as follows. --- Increasing the scope of other animal hair also applicable content, and ASTM standards with; --- Added Appendix A "test staple number" is determined to increase the number of staple test; --- Laboratory sample consisted of approximately 2kg increase to less than 4kg. This standard ASTMD1234-85 (2001) compared the main technical changes are as follows. --- Standard name changed to "natural wool staple length test methods"; --- Added Appendix A test to determine the number of staple; --- Did not use sampling spear-like tools and sampling methods. This standard replaces GB/T 6976-1986 "natural wool staple length of the test method." This standard is combined with the domestic situation, GB/T 6976-1986 made the following technical modifications. --- According IWTO-30-98 standard modified the definition of staple, staple length, will take to braid hair braided hair Cong Cong. --- Increased the principles described. --- Increasing the provision of batches of samples taken in accordance with the method and amount of stick in the appropriate product standards required by regulation. --- Addition of a prepared sample. --- Laboratory sample consisted of approximately 2kg increase to less than 4kg. --- Measure the length from the group changed from 10mm 5mm. --- Rounding off reservations digits after the decimal point to the 2-bit integer. --- Stepped up to take the model size. This standard Annex A, Annex B is normative appendix, Appendix C is informative appendix. This standard is proposed and managed by China Fiber Inspection Bureau. This standard is mainly drafted by. Shaanxi Provincial Fiber Inspection Bureau. The main drafters of this standard. Si Pui Xiuqin, Huang Chao, Chen Wucheng, Tian Yongjie, Lin Xiaoyu. Natural wool staple length of the test method1 ScopeThis standard specifies the test method for determination of the state of nature under natural wool staple length. This standard applies to the determination of natural wool staple length. This standard also applies to other animal hair.2 Normative referencesThe following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard. GB/T 8170 numerical rounding rules3 Terms and DefinitionsThe following terms and definitions apply to this standard. 3.1 When a pair of wool fiber without stretching, curling unspoiled, measured along the axis of staple obtained staple length. 3.2 Greasy hair taken as a whole, chiseled tow. 3.3 Top planar hair bundle. 3.4 Conical hair bundle. 3.5 Top it showed a braid-like staple. Principle 4 Length measurement instrument with a clump of hair samples obtained in the natural state length measurement to calculate the average length of its distribution parameters.5 ToolsVelvet panels, steel ruler (precision value 1mm), take the model.6 Sampling6.1 gross grant from randomly selected batches of samples in accordance with the method and amount of the corresponding product standards required. 6.2 batch samples at random from the laboratory sample, sample weight of not less than 4kg. 6.3 will be divided into laboratory samples, etc. after mixing 2 parts, one of which was used as sample preparation. ...... |
