| 主权项 | 1. A process for producing a reference body with a slot as a test crack for the nondestructive testing of materials, the process comprising: providing a reference body and a mask having a slot pattern with a sub-millimeter width; applying the mask to the reference body; removing material from the reference body through the mask with an abrasive water jet that consists of a pressurized abrasive suspension to form the slot having a predefined slot depth; including removing material with the abrasive water jet from a nozzle of a water jet apparatus having a diameter of 0.5 mm to 1.0 mm, and with a water jet with a pressure of 120 bar to 200 bar; stop removing material after a predefined machining time and removing the water jet apparatus; and removing the mask from the reference body. | ||
