All the information on material composition stored in the International Material Data System is known as IMDS-Data. Sinceautomobile manufacturers and suppliers are responsible for their product right from manufacture to re-cycling or disposal (refer also the End-of-Life Vehicle Directive) they have to conscientiously collect data on the material composition of products used in a vehicle. IMDS helps them with this since all the data required for subsequent re-cycling of vehicles are compiled with the help of the material data sheets.
Compiling Material Data Sheets
Each MDS (Material Data Sheet) contains relevant data on the material composition of a particular component, semi-finished product, raw material and basic substance, i.e. a summary of all raw materials used in the manufacturing process and proportional material components. Thus substances can be classified in security levels and the material composition of product parts can be reconstructed. There are specific guidelines for entry in compiling the material data sheets, called "Recommendations". Material data sheets are passed on to the client within the supply chain, who integrates the information into another material data sheet. The last one who needs to compile a MDS is the supplier of a component to the automobile manufacturer.
The data collected assists the automobile manufacturers ultimately in their task of summarising and analysing all data from the material data sheets, on components, assemblies, component groups and of an entire automobile. In this way the IMDS Data helps in documenting the entire manufacturing process of complicated components. The material data sheets are checked against the GADSL list before the automobile manufacturer releases them.
