Calculated Substances

The Substances (Calculated) tab shows the percentage weight of all substances in the material or compliance process.

For a compliance process, there is no weight information for the component substance. Materials Compliance Management uses "Unknown" as the weight value.

For a compliance process, you only see the Name/title, CAS Number, and EC Number columns.

If Unknown is set for the quantity type, all percentages will show the > symbol.

Column Name Description
All Applications:
% in Matl The total percentage of the material in all applications.
% IA in Matl The total percentage of the material that is intentionally added across all applications
% IR in Matl The total percentage of the material that is intentionally released across all applications.
Individual Applications:
% in Matl The total percentage of the material in the application.
% IA in Matl The total percentage of the material that is intentionally added in the application.
REACH Reg Status Indicates whether the substance has been registered for REACH.
REACH Pre-Reg Status Indicates whether the substance has been pre-registered for REACH.
% in Part The total percentage of the part in the application.
% IA in Part The total percentage of the part that is intentionally added in the application.
Worst Case Material:
% in Matl The weight of the substance classification in the worst case material based on the part BOM selected equivalent configuration containing the substance classification. The worst case material is the material that contains the largest percentage amount of this substance classification.
Description A description of the worst case material. This information is imported from and exported to the IPC 1752 reporting format.
Application Area A description of the application area for the worst case material. This information is imported from and exported to the JGPSSI reporting format.
Material Composition Info A description of the material composition information of the worst case material This information is imported from and exported to the JGPSSI reporting format.
Worst Case Intentionally Added Material:
% in Matl The weight of the intentionally added substance classification in the worst case material. The worst case material is the material that contains the largest percentage amount of this substance classification intentionally added.
Description A description of the intentionally added worst case material. This information is imported from and exported to the IPC 1752 reporting format.
Application Area A description of the application area for the worst case intentionally added material. This information is imported from and exported to the JGPSSI reporting format.
Material Composition Info A description of the material composition information of the worst case intentionally added material This information is imported from and exported to the JGPSSI reporting format.
Worst Case Component
% IA in Part For the listed worst case component, the percentage of the substance that is intentionally added in the part.
% in Part For the listed worst case component, the total percentage of the substance in the part.
