Foreword

The standard reference used ASTMD5867-05 "large-capacity fiber tester measured the physical properties of cotton fiber test method" (English Version). This standard adopts ASTMD5867-05 increase of the following. --- Physical characteristics using a cotton color standard sample check the calibration of the instrument. This standard compared with ASTMD5867-05, the main technical differences are as follows. --- The ASTMD5867-05 the scope of the "determination of any type of raw cotton color levy" is replaced by "other than cotton fiber colored cotton dimension". --- The standard color characteristic level is determined based on Chinese cotton color feature maps. --- This standard uses two standard temperate atmosphere GB 6529 regulations. This standard replaces GB/T 13784-1992 "Standard Test Method for cotton Color color measurement method." This standard compared with GB/T 13784-1992, the main contents of the revised as follows. --- Revised the scope of the standard, indicating that the standard does not apply colored cotton. --- Increased references to GB 1103 and GB 6529's. --- Increase in the standard test sample of the atmosphere humidity control requirements. (+ Chou) mean OK. --- Physical characteristics using a cotton color standard sample check the calibration of the instrument. --- Increasing the quality of not less than 125g per laboratory sample requirements. Appendix A of this standard is an informative annex. This standard is proposed and managed by China Fiber Inspection Bureau. This standard was drafted. Fiber Inspection Bureau of Shandong Province.
