This document replaces GB/T 11603-2006 "Determination of average wool fiber diameter by airflow method", and is consistent with GB/T 11603-2006 In addition to structural adjustments and editorial changes, the main technical changes are as follows. a) Changed the content of pre-conditioning and humidity control (see 6.1, 6.2, 6.3, 6.1, 6.2, 6.3 of the.2006 edition); b) Deleted the sampling method for raw greasy wool, scoured wool, carbonized wool and combed wool top batch samples (see 7.1 of the.2006 edition); c) The quality and quantity of samples have been changed (see 7.1.3, 7.2.3, 7.2.3.1, 7.2.3.2 of the.2006 edition); d) Changed the relative humidity tolerance range in Appendix E (see Appendix E, Appendix C of the.2006 edition). This document is modified to adopt ISO 1136.2015 "Determination of average diameter of wool fibers by airflow method". Compared with ISO 1136.2015, this document has more structural adjustments. Comparison list of structure number changes between two files See Appendix A. Compared with ISO 1136.2015, this document has more technical differences, and the vertical single Lines (|) are marked.
