SN/T 1062-2010Method of the inspection for content of cashmere in yarn and products for import and export (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

Instead of the standard SN/T 1062-2002 "import and export of yarn and fabric detection method in cashmere content." this standard compared with SN/T 1062-2002, the main technical changes are as follows.

--- Increasing the normative references

--- Increased 3.1 General;

--- Increasing the detection principle 3.3 cashmere velvet blended product content;

--- Increased 4.3 sample preparation;

--- Increased 8.3 yarn or fabric is detected in silk content of P2;

--- Increased 8.5 accuracy;

--- Increased appendix mohair morphological description;

--- Modify dissimilar to animal fibers and other animal fibers;

--- Modify fiber sample preparation 8.1.1;

--- 8.4 modify the relative error of more than 5% of the more than 3% absolute difference 8.1.4 ,;

--- The appendix cashmere density to 1.30g/cm3, increasing the density of mohair 1.32g/cm3;

--- Revision 8.4 cashmere content is calculated and added to the formula 8.4.2 weft fiber content inconsistent situation.

This standard is proposed and managed by the National Certification and Accreditation Administration Committee.

This standard by the People's Republic of China Hebei Exit Inspection and Quarantine is responsible for drafting.
