This part of IEC 62321 specifies the screening analysis of fluorine, chlorine and bromine in in polymers and electronics using Combustion- Ion chromatography (C-IC).  A (C-IC) screening analysis procedure for iodine can be found in an informative annex of this document. 

This test method has been evaluated for ABS (acrylonitrile butadiene styrene), EMC (epoxy molding compound), PE (polyethylene) and PC (polycarbonate) within the concentration ranges as specified in Table 1, 2 and 3.

The use of this method for other types of materials or concentration ranges outside those specified below has not been evaluated.

This Part of IEC 62321 specifies one normative technique for the determination of polycyclic aromatic hydrocarbons (PAHs) in polymers of electrotechnical products. Especially these PAHs can be found in the plastic and rubber parts of a wide range of consumers articles. They are present as impurities in some of the raw materials used in the production of such articles, in particular in extender oils and in carbon black. They are not added intentionally to the articles and do not perform any specific function as constituents of the plastic or rubber parts.

The gas chromatography–mass spectrometry (GC-MS) test method is suitable for the determination of polycyclic aromatic hydrocarbons (PAHs). 

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 between 37,2 mg/kg to 119 mg/kg and rubbers containing individual PAHs between 1 mg/kg to 221,2 mg/kg.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
