TEST SPECIMEN WITH IMPACT DETECTION MEANS

摘要

The present invention relates to a test specimen for visualizing mechanical impact in a mass production process, wherein the specimen comprises: - a body (18, 22, 32), - at least one impact detection means (15) at least partially covering a carrier structure of the body (18, 22, 32) and adapted to visualize mechanical impact impinging on the body (18, 22, 32). A protective coating or layer (17) covers the impact detection means (15) entirely.
