Germany Adds Polyaromatic Hydrocarbon Testing to GS Mark Requirements

Polyaromatic Hydrocarbons (PAH) Standard Required for GS (Geprüfte Sicherheit) Safety Testing

January 23rd 2008

The German Committee for Commercial Equipment and Consumer Products (ATAV) has now made previously voluntary testing for polyaromatic hydrocarbons (PAH) a standard requirement necessary for GS (Geprüfte Sicherheit) safety testing product certification. This will include electronic products intended for use in households and in the workplace.


The requirement will be implemented as an update to ZLS standard document ZEK 01-08, and will come into force on April 1, 2008. Certification will require test results demonstrating acceptable levels of PAH on user accessible
materials and surfaces of products, or where there is an apparent odor.

User inaccessible internal parts are not required to be tested. Test methodology is to be harmonized across all accredited testing facilities. The GS mark is a voluntary standard, but widely respected and observed, and recognized by CENELEC.


The PAH family of chemicals includes compounds with extended resonant cyclic structure, such as naphthalene, anthracene, tetracene, pentacene and higher compounds. They are used as additives in vulcanized rubber, as plasticizers, and as black pigments in polymers, among other applications. Some jurisdictions, such as Canada, are tracking PAHs onto legislated toxic substance schedules.
