The implementation of the operator's self-inspection, mutual inspection of workers and special inspection of full-time inspectors combined inspection system.

2. Double posts in key processes

Inspectors should be present at the same time when the operators are carrying out key processes, and the technical director or user acceptance representative should be present when necessary. Monitoring procedures must be carried out in accordance with the prescribed procedures and requirements.

3. Naming system

In the production process, from the raw materials entering the factory to the finished products leaving the warehouse, the person in charge should sign the process documents to show his responsibility for completing each process and changing a state of the products, including inspection, handover, storage and transportation.

4. Review system

Some enterprises that produce important products, in order to ensure the quality, safety and reliability of the delivered products or products participating in the test, have no hidden dangers, please check with the personnel of product design, production, test and technology departments before leaving the factory.

5. Traceability system

Traceability system is also called tracking management. In the production process, every time a process or a job is completed, the inspection results and existing problems should be recorded, and the names, time, place and situation analysis of operators and inspectors should be recorded, and the corresponding quality status marks should be made in the appropriate parts of the products.

6, statistics and analysis system

The workshop and quality inspection department of an enterprise make statistical summary, calculation and analysis of various quality indicators in production according to the requirements of the superior and the quality status of the enterprise, and report them to the factory department and the relevant departments at the superior level on schedule to reflect the changing law and development trend of product quality in production and provide reliable basis for quality management and decision-making.

7, nonconforming product management

Quality inspection is also an important part of the whole quality management. The management of nonconforming products should adhere to the principle of "three don't let go", that is, do not let go until the cause of nonconforming products is found out; Don't let go if you don't find out the responsibility; Failure to implement improvement measures.

8. Evaluation system

In quality inspection, due to the influence of subjective and objective factors, it is difficult to avoid or even happen frequently. According to foreign data, the inspector's missing rate of defects can sometimes be as high as 15%-20%. Methods for testing errors mainly include:

Repeated inspection, re-inspection and change of inspection conditions are adopted.

Extended data

The main basis of engineering quality control are:

1, project quality plan

This is the same as the project quality assurance, which is a planning document generated in the project quality planning.

2, the project quality work instruction

This is also the basis of project quality assurance, and it is also the working document produced in the preparation of project quality plan.

3, engineering quality control standards and requirements

This is a specific standard for project quality control based on project quality plan and project quality work description, which is generated through analysis and design.

4. The actual effect of engineering quality

The actual results of project quality include the intermediate results of project implementation and the final results of the project, as well as the quality of the project itself.
