Offering type ?
PRODUCT:
Component or system, which is commercialized. It is available for ordering multiple pieces and liability is assumed by the provider/seller. Necessary certification of the product was obtained (e.g. CE certification). The product sheet and/or conditions of use are defined.
PROTOTYPE:
Component or system, which has been successfully tested under real or real-like conditions. The prototype is not commercialized as the main purpose is to use it for demonstration and experimentation, including user and market acceptance.
TECHNICAL SERVICE:
Tools and processes and its combination, which are necessary to prepare and test prototypes or products.
