The Special Characteristics and Key Features Diagram is a document which identifies all key features and special characteristics.
The Special Characteristics and Key Features Diagram shall be used;
- to define production and laboratory ongoing periodic testing.
- as a template for identifying the reporting items for trial inspection reports
Minimum Content Requirements
- The Special Characteristics and Key Features Diagram shall include as a minimum:
All Special Characteristics
Dimensional key features. These may be in the form of:
- a diagram with dimensions, tolerances etc. appended;
- a diagram with reference table showing relevant dimensions, tolerances etc;
- a table of dimensions, tolerances.
Materials key features; (e.g. specification type / grade. Mechanical and or chemical properties).
Performance/ Function related key features (e.g. spot weld nugget size / strength, plating, contamination etc)
All key features shall be uniquely identified.
The supplier must ensure consistency throughout all documentation (e.g.: Control plan, Process Flow Chart , Special Characteristic and Key Features Diagram, Inspection Report, FMEA) for;
- operation step numbering
- product characteristics identification
Items or features controlled by SPC (Statistical Process Control) should be identified as such on the document.
