Korean Industrial Standards KS K 0733, KS K 0736 and KS K 0737 for determination of chlorinated phenols, allergenic disperse dyes and organotin content in textiles and/or leathers products respectively have been released.

These national standards in the Republic of Korea were developed by the Korean Agency for Technology and Standards (KATS) and distributed by the Korean Standards Association (KSA) in order to enforce product safety. The three standards for verifying the compliance of textile and/or leather products under the requirements of Korea Certification (KC Mark) are to be implemented immediately.

KS K 0733:2014 [1] – Test method for determination of pentachlorophenol (PCP), tetrachlorophenol (TeCP) and trichlorophenol (TriCP) content in textiles and/or leather (supersedes KS K 0733:2007):

  • Test specimen is extracted using an ultrasonic extractor and derivatized by acetic anhydride and triethylamine.
  • Instrumental analysis is done by Gas Chromatograph – Electron Capture Detector (GC-ECD) or Gas Chromatograph – Mass Spectrometer (GC-MS).

KS K 0736:2014 [2] – Test method for determination of allergenic disperse dyes content in textiles (supersedes KS K 0736:2007):

  • Test specimen is extracted in methanol using an ultrasonic bath at 70℃.
  • Instrumental analysis is done by High-Performance Liquid Chromatography (HPLC) – Diode Array Detector (DAD) / Mass Spectrometry (MS).
  • 22 allergenic disperse dyes are listed in the standard.

KS K 0737:2014 [3] – Test method for determination of selected organotin compounds content in textiles (supersedes KS K 0737:2007):

  • Test specimen is extracted using acidified methanol and derivatized by sodium tetraethyl borate, using tripropyl tin chloride as the internal standard.
  • Instrumental analysis is done by Gas Chromatograph – Mass Spectrometer (GC-MS).
  • 8 organotin compounds are listed in the standard.
