In order to ICT products be circulated and consumed in accordance with the State's current regulations, the products must be announced in accordance with the regulations of the Ministry of Information and Communications. The method of certification of conformity for products must conform to the management regulations in the respective technical regulations. Common certification methods today include:

Method 1: Typical sample test

Mode 1 tests typical samples of products and goods to conclude on conformity. The conclusion on conformity is valid for the type, type of product or goods that have been sampled for testing.

The order of execution of method 1 is as follows:

1. Sampling: Carrying out sampling for typical types, types of products and goods. Typical samples of products and goods are samples that represent a particular type or type of products or goods, which are manufactured according to the same design, under the same conditions, and using the same materials. The number of samples shall be sufficient for testing and storage.

2. Conformity assessment of test samples: Samples of products and goods are tested at a qualified laboratory, which may include the manufacturer's laboratory. Preferably use designated and accredited testing laboratories. The characteristics of products and goods to be tested and testing methods are specified in relevant standards and technical regulations.

3. Handling conformity assessment results: Reviewing the characteristics of products and goods through sample test results against the requirements of relevant standards and technical regulations.

4. Conclusion of Conformity Conclusion on conformity of products and goods with requirements of relevant standards and technical regulations. Products and goods are considered to be conformable if all the criteria of the tested sample conform to the prescribed levels of relevant standards and technical regulations.

Principle of using method 1

Method 1 is used to assess the conformity of products and goods with the following conditions:

• The design of products and goods allows to clearly identify products and goods according to each type or characteristic;
• The requirements to ensure the maintenance of quality stability have not been reviewed.

Method 5: Test type samples and evaluate the production process; monitoring through testing of samples taken at the production site or on the market in conjunction with assessment of the production process

Method 5 is based on the results of typical sample testing and evaluation of the production process to conclude on conformity. The surveillance assessment is carried out through testing samples taken at the production site or samples taken on the market combined with assessment of the production process.

The execution sequence of method 5 includes:

1. Sampling:

Proceed as specified in item 1 of Method 1.

2. Conformity assessment of test samples:

Proceed as specified in item 2 of Method 1.

3. Assessment of conformity of the production process:

The assessment of the production process must fully consider the manufacturer's control conditions related to product formation in order to ensure stable maintenance of product and goods quality. Control conditions include:

a) Control of technical documents of products (design documents, technical standards of products);

b) Controlling the entire production process from input, through intermediate stages to product formation, including packaging, loading and unloading, storage and transportation of products;

c) Quality control of raw materials, semi-finished products and finished products;

d) Control of technological equipment and measurement, inspection and testing equipment;

e) Control the skill level of workers and technical staff;

f) Other necessary technical contents.

4. Handling conformity assessment results:

Reviewing the characteristics of products and goods through sample test results against the requirements of relevant standards and technical regulations.

Consider the conformity of the production process with the requirements specified in section 3 of this method.

5. Conclusion on conformity:

Conclusion on conformity of products and goods with requirements of relevant standards and technical regulations. Products and goods are considered suitable if the following two conditions are satisfied:

a) All criteria of the test sample conform to the prescribed level of the relevant standards and technical regulations;

b) The results of the assessment of the production process are in accordance with the requirements.

Conclusions on the conformity of products and goods are valid for up to 3 years, provided that products and goods are assessed and supervised. Principles of using Method 5: Method 5 is used to assess the conformity of products and goods with the following conditions: It is necessary to use a method that is as reliable as method 4, but allows flexibility in the use of monitoring measures to reduce costs; A method of universal application should be used towards the mutual recognition of conformity assessment results.

6. Monitoring:

During the validity period of the conclusion of conformity, products and goods must be assessed and monitored through testing of samples taken at the place of production or taken on the market in combination with the assessment of the production process. . The frequency of surveillance assessment must be ensured no more than once every 12 months.

The testing of product and goods samples shall be carried out as specified in Sections 1, 2 and 3 of Mode 1.

The assessment of the production process is carried out as specified in section 1.3 of Method 2.

The results of the surveillance assessment will be used as a basis for deciding whether to maintain, suspend or cancel the notification of conformity.

Principles of using Method 5:

Method 5 is used to assess the conformity of products and goods with the following conditions:

• It is necessary to use a method that is as reliable as method 4, but allows flexibility in the use of monitoring measures to reduce costs;
• A method of universal application should be used towards the mutual recognition of conformity assessment results.

Method 7: Testing and evaluating batches of products and goods

Method 7 is based on the results of testing samples of products and goods taken according to the statistical probability method for a batch of products and goods to draw conclusions about the conformity of the batch. Conclusions of conformity are only valid for a specific batch of products or goods and do not require further monitoring measures.

Procedure 7 implementation sequence includes:

1. Sampling:

The test sample is a sample taken according to the method of statistical probability, ensuring representativeness of the entire lot. The number of samples shall be sufficient for testing and storage.

2. Conformity assessment of test samples:

Proceed as specified in item 2 of Method 1.

3. Handling conformity assessment results:

Reviewing the characteristics of products and goods through sample test results with the provisions of relevant standards and technical regulations.

4. Conclusion on conformity:

A batch of products and goods is considered to be in compliance with regulations if the number of samples tested with suitable results is within the allowable limits.

A batch of products and goods is considered nonconforming if the number of test samples with nonconforming results exceeds the allowable limit.

Principles of using Method 7:

Method 7 is used to assess the conformity of products and goods with the following conditions:

• Products and goods are identified in homogeneous batches;
• The requirements to ensure the maintenance of quality stability have not been reviewed.
