Testing method of abnormal fiber content for import and export polyester and acrylic staple fiber
People's Republic of China Entry-Exit Inspection and Quarantine Standards
Instead of the SN/T 0472-1995
Import and export of polyester, acrylic staple fiber defect content
test methods
Issued on. 2010-05-27

Foreword
This standard is in accordance with GB/T 1.1-2009 and SN/T 1103-2002 given in the drafting of the rules.
Instead of the standard SN/T 0472-1995 "import and export of polyester, acrylic staple fiber defect content measurement method."
This standard compared with SN/T 0472-1995, the main technical changes are as follows.
--- Added terms and definitions of terms in English;
--- The principle of representation has been modified, clearly artificial emulated and raw cotton picking machine analysis method, and points out their scope and
Respected method;
--- BISFA reference test method, modify the number of samples, laboratory samples and clearly, the number of test specimens;
--- Add "artificial hand picking Method" in "cotton type polyester, acrylic staple fiber content in the defect determination", the increase in raw cotton Parametric analysis English
Value system;
--- The "wool polyester, acrylic staple fiber content in the defect determination" to "medium and long wool polyester, acrylic staple fiber containing the defect
Determination of the amount of ";
--- Increase the "test report."
This standard is proposed and managed by the National Certification and Accreditation Administration Committee.
This standard was drafted. People's Republic of China Shanghai Entry-Exit Inspection and Quarantine Bureau.
The main drafters of this standard. Ye Zheng, Zhao Jie, Chen Qingdong, Ma Lijun, Chen Zhiwei.
This standard was first published in 1995 and 2010, the first revision.
