Foreword
This standard GB/T 6100-1985 "Test method for linear density of cotton fiber middles Law" was amended to retain the original time
Standards still apply the technical content of the standard GB/T 6100-1985 major amendments to the following.
1. According to GB/T 1.1-2000 "Standardization Guide Part 1. Standard structure and drafting of rules" to modify the cover and braid
Write format, increasing the preface and the normative references, while changing each chapter number.
2. Increased measurement speed in 5.3, human error is small electronic balance.
3. The 1985 version 6.1 "hand pull finishing times" was revised to 8.1 in this edition of "hand-pulled finishing 2 times to 3 times."
4. The 1985 version 7.2 on a digital rounding Rules revised to 9.2 edition of "rounding off according to GB/T 8170 carried out."
Appendix A of this standard is an informative annex.
