A Material MDS may contain public norms or OEM company norms. Company norms are visible only for the company the norm belongs to and are not visible along the supply chain. Under Recipient Data the originally selected norms for the Material MDS are listed. The Tier1 supplier may overwrite the norms as recipient-specific data. These entries exist in parallel to the original values which are part of the (referenced) Material MDS. For each Material MDS occurrence (based on IMDS-ID/Version) one entry exists. IF more than one (company-) norm for such an MDS exists, these are comma-separated and listed as the 'Norm/Norm Code'. For those Material MDSs without norms assigned, norms can be added by the Tier1 supplier
