1, Design with series-production status;
2, Produced out of series materials with series tools;
3, Products to be built within pre-tryout/production tests;
4, D1 sample: first parts with series production tools and series geometry and materials-have been manufactured under conditions that are close to series;
5, D2 sample: as D1-produced under full series conditions.
Objective
1, Suppliers complete all quality-relevant tests;
2, D1: last confirmation through development, type testing, pilot series (pre-tryout), homologation;
3, D2: Proof that part conforms to series documentation (part successfully sampled (ISIR/EMPB), maturity for production test/tryouts is obtained).
Application
Testing of all production relevant factors.
C Sample
Manufacturing
1, Functionality and product characteristics similar to series: Fine-geometry (Radiusesy, form, grain ...) and materials are very close to series (not necessarily made with series tools)
2, Principle of manufacturing:
Production processes close to series processes (not necessarily made with series tools). Further processing oftern hand-made.
Objective
1, Assure installation, functionality, characteristics, mechnical strength and reliability;
2, Surface quality is closed to series;
3, Package space requirements within the vehicle and the positioning of contact points meet assembly requirements;
4, Reach drawing geometry "series";
5, Assure maturity so that production equipment can be ordered and tool manufacturing is ensured.
Application
1, Reliability tests on (overload)-test bench;
2, Tests with first target vehicle
B Sample
Manufacturing
Made with prototype tools (not necessarily made out of series materials)
Objective
1, Verification: Function Prognosis: Reliability;
Functionality, geometry, surface, connection technique, haptics, mechanical and electric/electronic requirements, temperature tests, basic durability etc. have to ensure future characteristics of the series product (suppliers have to show alll deviations)
2, Initial cost analysis on part level is available;
3, Intial status of the FMEA is considered;
4, Basis for make-or-buy decision and prodcution concept
Application
Installation tests and function tests are carried out on test bench, e.g. within entire aggregate or vehicle
A Sample
Manufacturing
Made with prototype tools or hand-made (not necessarily made out of series materials)
Objective
1, Assurance of innovations, respectively technical concepts (finalization of advanced development);
2, Assurance of the decision on alternative, competing product concepts;
3, Existing requirements regarding functionality and packaging space within the vehicle are identified (perspective: requirement specification) Requirements are evaluated with respect to the componnet (no focus on life-time/durability capability)
Application
Function and independent component tests without environment conditions (possibly within the aggregate carrier)
