CHLORINE/BROMINE CONTENT – The halogen content of interest to be quantified for each material is to be obtained using a combustion flask sample digestion technique and apparatus essentially similar to that described in the Standard Test Method for Chlorine, Bromine, or Iodine in Organic Compounds by Oxygen Flask Combustion, ASTM E 442, or other equivalent means. Quantitation is then carried out by either vacuum UV Inductively Coupled Plasma (ICP) spectrometer instrumentation, ion chromatography (IC) or silver nitrate titration.
