The adoption of the IMDS relies above all on a legislative background, namely:
The IMDS is the result of a collaborative effort involving 8 OEMs, namely Audi, BMW, DaimlerChrysler, Ford, Opel, Porsche, VW and Volvo. Since its establishment further OEMs have also adopted this system.
With the introduction of IMDS, BMW, DaimlerChrysler, Porsche, Fiat, Ford, General Motors, Toyota, VW and Volvo combined their lists to the ILRS (international list of reportable substances) which has been replaced by GADSL (global automotive declarable substance list). The remaining OEMs still have their own lists and currently most of the OEMs accepting the GADSL still have complementary requirements. Because of ongoing research and lawmaking, these lists are subject to change.
Because it is a computer-based system, IMDS recognizes hazardous substances by comparing the entered data with the lists of prohibited substances. Hence OEMs can trace hazardous substances back to the source and eliminate them.
Not only the banned materials (Cr VI / Hg /...) have to be indicated. Instead, all substances have to be stated in the material data sheet (MDS) of the IMDS with a resolution of 1 gram or better. That is why substances and materials of products must be known in detail. Material information on parts is later delivered from the OEMs to dismantler companies in order to achieve the goals of the ELV Directive.
