Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 16831 was prepared by Technical Committee ISO/TC 135, Non-destructive testing, Subcommittee SC 3, Ultrasonic testing. v
Introduction This International Standard is based on EN 15317:2007, Non-destructive testing Ultrasonic testing Characterization and verification of ultrasonic thickness measuring equipment. The following International Standards are linked. ISO 16810, Non-destructive testing Ultrasonic testing General principles ISO 16811, Non-destructive testing Ultrasonic testing Sensitivity and range setting ISO 16823, Non-destructive testing Ultrasonic testing Transmission technique ISO 16826, Non-destructive testing Ultrasonic testing Examination for discontinuities perpendicular to the surface ISO 16827, Non-destructive testing Ultrasonic testing Characterization and sizing of discontinuities ISO 16828, Non-destructive testing Ultrasonic testing Time-of-flight diffraction technique as a method for detection and sizing of discontinuities viii
