Non-Destructive Testing – Integrated
Non-Destructive Testing – General Principle
1 Scope
This Standard specifies the general principles for integrated non-destructive testing of
materials and workpieces.
This Standard is only applicable to materials or workpieces that may be subjected to
two or more non-destructive testing methods. Various non-destructive testing methods
may be implemented in accordance with their own testing standards, and may also be
implemented in accordance with the testing standards of integrated non-destructive
testing methods.
This Standard is applicable to the integrated non-destructive testing method whose
main feature is the integration of multiple non-destructive testing technologies. It is not
applicable to the integrated non-destructive testing method whose main feature is the
integration of a single non-destructive testing technology and multiple interdisciplinary
industrial technologies.
This Standard provides guidance for the formulation of integrated non-destructive
testing standards or testing procedures for specific products, equipment, and materials.

3.1 Integrated non-destructive testing
A comprehensive technology that integrates two or more independent non-destructive
testing methods or technologies, has integrated testing apparatus and/or sensor
hardware structure and integrated software structure, and can perform comprehensive
processing like data fusion against the acquired test data and realize resource sharing.
It is the main feature of integrated non-destructive testing to realize the integration of
multiple non-destructive testing methods through the organic integration of multi-
disciplinary technologies such as machinery, electronics, and information. When
integrating non-destructive testing, the scanning mechanism and discontinuous
position information of different types of testing methods are shared; the sensors of
different testing methods have an integrated structure and become an organic whole;
the excitation and/or receiving circuits, and the analog-to-digital conversion circuit of
different testing methods are shared. By integrating the testing information of different
types of non-destructive testing methods, the surface and internal discontinuities and
discontinuities of different directions of the tested object can be tested at the same
time; it can also test and characterize the surface performance and/or stress state, etc.
of the tested object. Therefore, the integrated non-destructive testing apparatus has
better economy, the testing process has higher efficiency, and the accuracy and
reliability of testing results are higher.
4.2 Technology
Integrated non-destructive testing generally includes the following modes such as non-
destructive testing instrument integration, non-destructive testing network integration,
and non-destructive testing cloud testing, etc.
The testing performance of the integrated non-destructive testing equipment shall be
better than the simple sum of the testing effects of each single testing method, and has
the following advantages:
--- Economy of the apparatus;
--- Comprehensiveness of testing information;
--- High testing efficiency;
--- Full coverage of the testing range;
--- Accuracy and reliability of test results, etc.
Integrated non-destructive testing includes but is not limited to the following technology
combinations:
--- Eddy current-magnetic memory integrated testing technology: The combination
of eddy current sensors and magnetic memory sensors are distributed on the
same scanning surface of the sensor to form an integrated working sensor, which
can simultaneously pick up discontinuities and stress abnormalities information
at the same position of the tested ferromagnetic workpiece;
--- Eddy current-electromagnetic ultrasonic integrated testing technology: Excite
and receive eddy current and ultrasonic signals in the tested metal workpiece,
which can simultaneously test the surface, near surface and internal
The usual testing objects are:
--- All kinds of raw materials, and all kinds of workpieces;
--- Transportation vehicles, such as ships, rail vehicles, aerospace vehicles;
--- large infrastructure;
--- Power system facilities;
--- Petroleum and petrochemical-related pipelines, storage tanks, and drilling
platforms;
--- Other major facilities, equipment and components.
5 Safety
This Clause does not list all the safety requirements for testing. Users of this Standard
shall establish safety guidelines before testing.
