4.3 Classification
According to the data entry mode, non-destructive cloud testing may be divided into
two modes: manual data collection and automatic data collection.
According to the data source, non-destructive cloud testing may be divided into regular
testing, patrol testing and monitoring.
5 Security Requirements
5.1 General
This Clause does not list all the security requirements for the implementation of testing.
Users who use this Standard shall establish security guidelines in accordance with the
requirements of GB/T 36951, GB/T 37024, GB/T 37025, GB/T 37044 and GB/T 37093
before testing.
5.2 Security requirements for sensor installation
Security requirements such as non-destructive and explosion-proof of the test object
shall be ensured according to the test object and its working conditions.
Avoid falling, electric shock and other personal injuries during installation.
5.3 Data and transmission security requirements
5.3.1 Overview
The data transmission security of non-destructive cloud testing requires that all data
shall be transmitted between legal cloud-testing terminals and the cloud; and the
transmitted data shall not be illegally accessed, copied or modified.
Security measures include identity authentication of testing sensors, cloud-testing
terminals and cloud; and the confidentiality of transmitted data.
Confidential data shall be taken security measures by the data controller himself; and
shall be processed by a local area network approved by the data controller.
5.3.2 Identity authentication
Identity authentication shall ensure that the cloud identifies the identity of the cloud-
testing terminal; and provide the cloud-testing terminal with access rights matching the
identity of the cloud-testing terminal. If the identity authentication is in two-way, the

9 Requirements for Cloud
9.1 Basic functions
The cloud may be a private cloud based on a local area network, or a public cloud
based on a wide area network. It shall have the following functions such as information
verification, data reading and data storage, as well as signal processing, data analysis,
data calculation and interpretation for non-destructive testing methods, etc. The most
important functions of the cloud are cloud storage and cloud computing.
9.2 Cloud storage
Cloud storage collectively stores test signals, test human-computer interaction data,
image data during the test process and other test-related data; and provides functions
such as dynamic collection, query and read. The storage time shall at least meet the
user's requirements. In the process of acquiring, saving and reading, ensure that the
data is not tampered.
9.3 Cloud computing
Cloud computing shall include the following:
--- Simulation: Use the computer to calculate the process of test signal generation,
signal transmission and sensor signal pickup; and display the influence of the
nature and discontinuity of the test object on the signal and the effect on the test
result;
--- Processing: Process the test data uploaded to the cloud to improve sensitivity or
enhance the intuitiveness of the test results;
--- Calculation: Calculate the discontinuous quantitative, semi-quantitative size and
other information from the test conditions, environment, physical characteristics
of the test object and the acquired test signal;
--- Evaluation: Use the test information and its calculation results to give a
discontinuous grade evaluation.
9.4 Information verification
Information verification is the basis of fairness and reliability for cloud test services.
The cloud shall verify the non-destructive cloud test terminal through data encryption.
The implementation process shall consider the following aspects:
--- Test standards;
--- Obtain or enter the information of the test object;
--- Obtain or enter the information of test personnel;
--- Connect sensors and cloud-test terminals;
---Verify the status of sensors and cloud-test terminals;
