The IECEE Hazardous Substances Testing Service (HSTS)
Concern over the presence of hazardous substances in electrical and electronic products has led many countries to pass legislation restricting their use.
Electric and Electronic (E&E) product and component manufacturers and suppliers need to comply with ever intensifying regulations and requirements worldwide and must ensure that their products meet different national and regional regulations to be marketed and to avoid possible recalls or legal suits.
Six substances are considered as having potentially serious negative impact on human health and the environment:
- Lead (Pb)
- Mercury (Hg)
- Cadmium (Cd)
- Hexavalent Chromium (Cr(VI)
- Polybromobiphenyl (PBB)
- Polybromodiphenyl ethers (PBDE)
The IECEE Hazardous Substances Testing Service (HSTS) offers an excellent way of demonstrating restricted contents of the hazardous substances in a product, and showing compliance with the relevant national regulations in different countries.
Tests for identification and measurement of the hazardous substances are currently performed according to IEC 62321:2008, Electrotechnical products - Determination of levels of six regulated substances (lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers).
A manufacturer can demonstrate whether the percentage of hazardous substances in the parts and materials of its product comply with the relevant regulations through a Statement of Test Results (STR) issued by an internationally-recognized IECEE National Certification Body (NCB).
The STR is based on an associated Test Report issued by an IECEE qualified and accepted CB Scheme Testing Laboratory (CBTL). NCBs issue STRs online on the IECEE website.
Why use the international Hazardous Substances Testing Service?
The IECEE HSTS offers applicants third-party test reports and attestations and IEC 62321 provides appropriate test methods. A Statement of Test Results and associated test report based on this Standard imply a precise analysis to verify the percentage of hazardous substances in the materials/parts of the product according to the relevant regulations in different countries.
STRs are widely recognized by authorities and in the global market place, as well as by other NCBs within the IECEE CB Scheme.
Current legislation status
In the European Union (EU), the Restriction of Hazardous Substances Directive (RoHS) and the Waste Electrical and Electronic Equipment Directive (WEEE) came into effect in 2006. Both Directives have since evolved, RoHS in 2011 and WEEE in 2012.
In addition to EU member states and associated countries including Iceland, Lichtenstein, Norway and Switzerland, several other industrial countries, such as Australia, China, Japan, South Korea and the United States now have similar legal restrictions on the use of hazardous substances.
