This is the regulatory European product marking allowing access to the EU/EEA member countries (and even some EU candidate countries in Eastern Europe), as dictated by EU Directives and corresponding national regulations.
The GS mark (Geprüfte Sicherheit, meaning Tested Safety) is a specific German mark that is used for a wide range of products, including electrical equipment.
The GS mark is owned and monitored by the German safety authorities, but is offered through Nemko. It is highly recognized not only in Germany, but also throughout Europe.
The Hazardous Substance Testing Service (HSTS) is offered as a part of the IECEE CB scheme. It is a means of determining and reporting the level of hazardous substances in materials and components used in electrical equipment.
This means that there is a major need for reliable tools to verify and demonstrate the level of HS in electrical products. The IECEE HSTS were developed with this need in mind.
Tests are performed according to the latest IEC International Standards on hazardous substances as defined by IEC 62321.
The Statements of Test Results are issued online by Nemko on the IECEE website.
