<P>PROBLEM TO BE SOLVED: To provide a standard sample manufacturing method for nondestructive inspection allowing hydrogen of a desired concentration to be added to a desired portion of a titanium material and allowing standard samples to be manufactured with ease and in large quantities, a standard sample for nondestructive inspection, and a nondestructive inspection method using the same. Ž<P>SOLUTION: In a treatment process, the base metal of a portion of a titanium pipe 7 with hydrogen added thereto is exposed and portions other than the portion with hydrogen added thereto are coated with a coating part 9. In a placement process, a reference electrode 3, a counter electrode 4, and pretreated titanium material 7 serving as a working electrode are placed in an electrolytic solution of a three-electrode mode electrochemical cell. In an application process, a constant current or a constant potential is applied on the titanium pipe 7 for a prescribed period of time by a galvanostat 2. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
