GADSL Update



Two changes to SC90 checks were implemented in IMDS. These changes are already listed in the check message document (which also includes the IMDS Release 14.0 check changes) available in the IMDS FAQ.

Allow Silver >80% in glass (classification 7.2)

Currently, a warning is shown in the check result in case a material of classification 7.2 contains >80% metallic substances (substance group “Chk: Classification 1-4”).
To allow the creation of conductive glass materials, which may contain more than 80% of silver, the following change will be implemented: 

  • A new substance group “Chk: Classification 1-4 w/o silver” will be created, which will contain all metallic substance except for silver.
  • The existing check will be adapted to refer to this new substance group. Thereby, silver will be excluded from the existing check and materials of classification 7.2 may contain an unlimited portion of silver.

Allow Iron >14% in all metals (classifications 1.x – 4.x)

Currently, a warning is shown in the check result in case a material of classification 2.x – 3.x or 4.1 contains >14% iron.
To allow a reasonable portion of iron in different alloys (e.g., nickel alloy classified as 3.4), all metallic classifications (1.x – 4.x) will be allowed for iron portions >14%.



Mazda updated their IMDS Supplier information. You can find more information in the section "OEM Specific Information" > Mazda.


With the changes of IMDS Recommendations 007, 008, 011 and 012 in September 2022, the IMDS Steering Committee removed several published materials from these recommendations, which were not defined by any norm. In a next step, these materials were decided to be hidden, as the IMDS Steering Committee can only take responsibility of materials that are described in norms. The Zentralverband Oberflächentechnik (ZVO), who supported in the creation of the surface treatments, offered to take over the responsibility and maintenance of the surface treatments they supported for the above mentioned Recommendations.

In January 2023, the surface treatments from ZVO have been moved to the company Zentralverband Oberflächentechnik [10216] and all other materials that have been removed from the above mentioned Recommendations have been hidden and cannot be further used in new MDSs. As the MDSs moved to ZVO are issuing warnings for used ranges, the IMDS Steering Committee decided to temporarily exempt the moved MDSs from IMDS checks, similat to the IMDS Standard Material suppliers. Therefore, Zentralverband Oberflächentechnik [10216] is temporarily added to the IMDS Standard Material suppliers and their MDSs are exempt from the IMDS checks.

The IMDS Steering Committee asks all suppliers in IMDS to not reject MDSs for the used ranges in materials by Zentralverband Oberflächentechnik [10216]. 



The Joker-Playbook was added to the VW supplier guideline with background and application information on the IMDS function “confidential pure substances”.. More information can be found under OEM-specific info > Volkswagen.
