Foreword

SN/T 1690 "new textile fiber component analysis" is divided into two parts.

--- Part 1. soybean protein fiber content assay nitrate;

--- Part 2. PTT, PBT fiber nuclear magnetic resonance spectroscopy.

This section SN/T 1690 Part 2.

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

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

1 Scope
