UD and UF (with two possible additions for each)

further calibration can be performed using a reference sample for better measurement accuracy which will save a lot of time and resources

policy formulation

This Part of IEC 62321 specifies one normative and two informative techniques for the determination of polybrominated biphenyls (PBB) and diphenyl ethers (PBDE) in polymers of electrotechnical products

It sets measures to address risks and also to minimize accidents to users for those involved in the design
