There are many regulation in the world requesting declaration or limitation of substance content in products: REACH, RoHS, … To know if a substance is contained above or below the regulated threshold, a method to measure the substance must be used. This is why TC111 is developing standardized test methods for these regulated substances. By using this standardized methods, the measurements are comparable. This is a real benefit for the industry.

TC111 has 2 groups to develop these methods:
WG3 and JWG14

IEC/TC111/JWG 14

ISO/IEC double logo standardization for Test methods of certain substances in polymers

Established in 2019 February between IEC/TC 111 & ISO/TC 61(Plastics) / SC 5 (Physical and chemical property)

Initiative project of JWG 14; IEC 62321-11 “Determination of certain substances in electrotechnical products – Part 11: Tris (2-chloroethyl) phosphate (TCEP) in polymers and electronics by gas chromatography-mass spectrometry (GCMS) and liquid chromatography-mass spectrometry (LC-MS)”


Future of the work

Short term: 2020

Harmonize with IEC/TC 111/WG 3 and ISO/TC 61/SC 5

Long term: 3-5 years

Harmonization between WG 3/JWG 14 and Others TC, development of more substances testing standards, find a way to collaborate with test labs, have a Conformity Assessment scheme in place, ….
