Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard SN/T 0120-1992 "import nylon, Polyethylene, Polypropylene heald qualitative analysis."
This standard compared with SN/T 0120-1992, the main technical changes are as follows.
--- Increasing the related terms and definitions;
--- As a qualitative analysis rather than for the inspection, sampling method and the number deleted;
Cyclohexane and decalin solvent --- the original standard "dissolution test method" used, revised toluene and xylene;
--- Update the infrared spectrum, the abolition of legal dissolution of the film, added in 2002 after the new IR sampling technique --- attenuated total
Reflection (ATR) method, and some way of expression has also been modified.
This standard is proposed and managed by the National Certification and Accreditation Administration Committee.
This standard was drafted. Tianjin People's Republic of China Exit Inspection and Quarantine.
The main drafters of this standard. Zheng Yun, is Zhu Tong, Lei Zhou.
This standard replaces the standards previously issued as follows.
--- SN/T 0120-1992.
Import and export of nylon, Polyethylene, Polypropylene Heald
Qualitative analysis
1 Scope
This standard specifies the steps nylon, Polyethylene, polypropylene three kinds heald by gravity method, dissolution method, melting method, infrared spectroscopy of identification.
This standard applies to the import and export of nylon (nylon 6), Polyethylene (PE), polypropylene qualitative identification (polypropylene) healds.

GB/T 14666-2003 analytical chemistry terms
3 Terms and Definitions
GB/T 14666-2003 define the following terms and definitions apply to this document.
3.1
Nylon polyamidefibre
Polyamide fiber as raw material is made of spun 6.
3.2
Polyethylene polyethylenefibre
Made of polyethylene fibers spun at high pressure ethylene polymerization obtained.
3.3
Polypropylene polypropylenefibre
Petroleum cracking is separated from propylene gas as raw material, after polymerization of polypropylene resin spun into fibers.
3.4
Infrared absorption spectrometry infraredabsorptionspectrometry
Infrared radiation and sample molecular vibration and (or) rotational levels of interaction, the use of infrared absorption wavelength and absorption band position
Strength analysis to determine the composition of the sample, the molecular structure and the like.
3.5
Attenuated Total Reflectance attenuatedtotalreflection; ATR
A method for measuring a high absorption of the sample or sample surface, greater than the critical angle of the infrared light incident at an angle close to the sample surface to a high
The refractive index of the crystal, since the sample refractive index lower than the crystal, total reflection infrared light into the sample only a very shallow surface layer, only certain frequencies
Is absorbed, the measured radiation is attenuated, whereby attenuated total reflection spectra of the samples.
Principle 4
Have different densities based on nylon, Polyethylene, polypropylene three kinds heald different solubility, different heat resistance, different IR, mining
By density method, dissolution method, melting point, infrared spectroscopy were identified.
