Delete the "Normative references" in reference to the standard GB 1103, GB 6097; "GB 6529" replaced by a direct reference to "ISO 139". 2. Delete "Definitions and terminology" in the "span length", "fiber quantity" because the novel HVI use of "upper half mean length", and the text It did not involve "the number of fibers." 3. references and terminology of individual normative regulate. Such as. Delete "span length", "the number of fiber" and other definition. "micronaire micronairereading "norms of interpretation as" a certain amount of cotton fiber micronaire micronaire under specified conditions, a measure of permeability to Micronaire scale representation.
