Electrotechnical screening analysis update

The use of certain metals, fire retardants and plasticising agents in the manufacturing of electrotechnical products is subject to restrictions by RoHS (Restriction of Hazardous Substances) to protect both human health and the environment.

Substances such as Lead (Pb), Cadmium (Cd), Polybrominated Diphenyl Ethers (PBDEs) and Phthalates are also a concern in current and proposed regional legislation.

The previous version of the International Electrotechnical Commission (IEC) from 2013 to determine certain hazardous substances in electrotechnical products, only included Bromine (Br) in homogeneous materials found in polymers by using combustion ion chromatography (CIC). This screening method has been updated in 2020 and replaces the previous version.

In the current IEC 62321-3-2:2020 RLV edition, a screening method by CIC for Halogens such as Bromine (Br), Fluorine (F) and Chlorine (Cl) has been added as a normative part of the document and a screening method by CIC for Iodine (I) has been added to the annex.

The test method by CIC has been evaluated for ABS (acrylonitrile butadiene styrene), EMC (epoxy moulding compound), PE (polyethylene) and PC (polycarbonate).

CIC is now the official standard testing method for screening Fluorine, Chlorine, Bromine and even iodine in polymers and electronics.
