IEC 62321-10-2020 pdf free.Determination of certain substances in electrotechnical products – Part 10: Polycyclic aromatic hydrocarbons (PAHs) in polymers and electronics by gas chromatography-mass spectrometry (GC-MS).
These test methods have been evaluated for use with plastics and rubbers. These test methods have been evaluated for use with ABS (acrylonitrile butadiene styrene) containing individual PAHs ranging from 37.2 mglkg to 119 mg/kg and rubbers containing individual PAHs ranging from 1 mg/kg to 221,2 mg/kg.

4 Principle
PAH compounds are quantitatively determined using ultrasonic extraction or Soxhlet extraction followed by gas chromatography-mass spectrometry (GC-MS) using single (or seIected) ion monitoring (SIM),
5 Reagents and materials
Use, as far as available, reagents of analytical quality, or better. Use only reagents with negligibly low concentrations of PAH and verify by blank determinations and, if necessary, apply additional cleaning steps (for calibrants, see 8.4):
a) Dichloromethane (GC grade or higher).
b) Helium (purity of greater than a volume fraction of 99,999 %).
c) Silica gel (purity of greater than a mass fraction of 99 %).
d) Toluene (GC grade or higher). IEC 62321-10 pdf free download.
