Stability and reliability issues have become obstacles to the development of instrumentation in China

　　 The reliability and stability of domestic instrumentation and automation systems are very different from those of foreign products. Its reliability issues have shaken the confidence of key industries such as metallurgy, electric power, and petrochemical industries in domestic products. As a result, localization of instrumentation and automation systems has been the slowest in the nationalization of major national technical equipment. Greatly affected the improvement of equipment manufacturing technology and product quality. The stability and reliability issues have become a serious obstacle to the development of China's instrumentation industry and technological innovation.

Reliability work is a comprehensive job. From the system point of view, the reliability work needs to eliminate and control all kinds of unreliable factors to the maximum extent possible in the entire product life cycle, and maximize the detection of unreliable factors. Defects, in order to achieve the most cost-saving, the most time-saving operation of the established reliability goals. It involves aspects such as product performance effectiveness, functional safety, service life, maintainability, environmental adaptability, and the full life cycle cost of the product. Reliability work requires systematic theoretical research, long-term data accumulation, careful experimental argumentation, and extensive investigation and analysis.

After nearly a month of waiting, the “Ai Shuangmen” question team got the answer in the first week of the new year. Yesterday, the Hainan Provincial Administration for Industry and Commerce released the latest survey results, arguing that it was mainly due to technical reasons that caused mistakes in the initial inspection and quoted a letter from the Inspection and Quarantine Technology Center of the Hainan Provincial Entry-Exit Inspection and Quarantine Bureau, saying that the instrument was aging and its status was unstable and the test results showed deviations. Instruct Haikou City Bureau of Industry and Commerce to apologize to consumers and related companies.

After the announcement of the announcement, some people questioned how "the instrument's aging caused distorted results. Then how do you believe the results of previous tests?" Some people commented: "You can blame the program and you can blame the machine. The ultimate damage is government departments. Credibility."

Haikou Industry and Commerce paid more than 80,000 yuan inspection fee

The Hainan Provincial Administration for Industry and Commerce provided a “Notification on the Investigation of Haikou City Administration of Industry and Commerce on the Sampling of Farmers Springs and the Unified Enterprise Beverage Event” (hereinafter referred to as “Notification”).

The "Announcement" said that on October 16 and 17, 2009, Haikou City Industrial and Commercial Bureau successively placed a total of wholesale stores, supermarkets, and stores in Carrefour South Asia Plaza in Haikou, as well as in aquatic products docks, Lingshan Town, and Guilin Yang University Town. A total of 50 samples produced by 35 companies, including Nongfu Springs and a unified company, were collected. In fact, after the preliminary inspection results were announced, related companies first questioned the source of the sample, and believed that the product may be packaged at the circulation or not necessarily the product produced by the company.

Interestingly, the "Notification" disclosed that the Haikou Bureau of Industry and Commerce for the first time to find the inspection unit is not the Hainan Provincial Entry-Exit Inspection and Quarantine Bureau Inspection and Quarantine Technology Center. The "Announcement" said that after sampling, the Haikou City Administration for Industry and Commerce contacted Haikou Municipal Center for Disease Control and Prevention, a long-term cooperation unit, and requested samples to be sent to the center for inspection. After understanding the inspection requirements, the center stated that it could not complete the task as required. The Haikou Municipal Administration for Industry and Commerce contacted the Inspection and Quarantine Technology Center of the Hainan Entry-Exit Inspection and Quarantine Bureau.

The "Announcement" also disclosed that on October 19, 2009, according to the requirements of the Inspection and Quarantine Technology Center of the Hainan Entry-Exit Inspection and Quarantine Bureau, the Haikou Municipal Administration for Industry and Commerce sent samples to the center and handled the entrusted inspection procedures on the spot, paying 8 Million yuan inspection fee.

The inspection department said "the state of the instrument was unstable"

On December 2, 2009, the Hainan Provincial Administration for Industry and Commerce established an investigation team headed by the director of the Ministry of Industry and Commerce, and conducted an in-depth investigation of the incident. The investigation took the form of interviews, transfer of evidence, and visits to companies. It lasted 21 days.

The "Announcement" said that although the sampling inspection conducted by the Haikou Administration for Industry and Commerce and the issuance of the "Consumer Warning" were conducted in accordance with laws and regulations, there was a problem of improper procedures. First, the Haikou City Administration of Industry and Commerce did not fully implement the provisions of the State Administration for Industry and Commerce when sampling. Work processes also fail to require the inspection agency to notify the nominal food producer of the test results. After the company requested a re-inspection, Haikou City Administration of Industry and Commerce directly submitted inspections and did not meet the procedural requirements without reaching an agreement with the company on the details of the review. Secondly, the Haikou City Administration for Industry and Commerce released the “Consumer Warning” in the media without prior notification of the notification process and published the wrong information, thus causing an adverse effect on the production enterprises.

The main reason for the above-mentioned problems was that the results of the preliminary inspection were incorrect. The "Announcement" stated that on January 4, 2010, the Inspection and Quarantine Technology Center of the Hainan Provincial Entry-Exit Inspection and Quarantine Bureau wrote a letter to Hainan Provincial Administration for Industry and Commerce to apologize: "Because of technical problems in our technical center, we sent it to Haikou Administration for Industry and Commerce. We are sorry for the negative impact of our work."

"The Bulletin" quoted the letter saying that the main reason for the erroneous results of the initial inspection was: "The first is the decrease in the sensitivity of the atomic fluorescence spectrophotometer used for total arsenic detection. The instrument has a useful life of almost nine years. The standard curves drawn were analyzed, and the state of the instrument was unstable at that time, especially the large deviation of the low point of the standard curve, which had a certain impact on the detection results.The second was that the sample preparation was not strictly performed according to the standard method and the volume was determined. Shortens the inspection time, reduces the sample weight, and increases the dilution factor of the sample. This increases the probability of deviations in the measured value when the instrument state is unstable.
