With the process of China's accession to the WTO and the integration of the world economy, China's weighing apparatus companies pay more attention to the international market. Weighing apparatus products have been exported to 143 countries and regions around the world. These enterprises also encountered some difficulties and technical barriers in international trade while their product exports continued to grow. As scales are products of legal management, countries around the world attach great importance to their quality and have established a number of metrology and technical institutes to confirm the compliance of scales. This has caused each type of weighing instrument to be exported to a country in international trade must be repeated testing, forming a practical technical barriers, but also become the main obstacle for China's weighing enterprise to further expand international trade. In order to avoid and eliminate such technical barriers, weighing companies in China should use the WTO/TBT technical barriers agreement and actively apply for OIML certificates of measurement instruments. Only in this way can we realize the facilitation and liberalization of weighing instruments' international trade and expand the export of weighing instruments. Quantity and export areas.

OIML is an international legal measurement organization with 60 formal members and 49 communication members, and developed countries have basically joined the organization. The OIML certification system is a certification system for measuring instruments and is a system for issuing, registering and using certificates for measuring instruments that comply with OIML's international recommendations. The manufacturer of measuring instruments can voluntarily apply to the issuing agency (AQSIQ) OIML China Secretariat. The issuing authority entrusts the designated laboratories to test the prototypes provided by the manufacturer in accordance with the corresponding international recommendations after reviewing the qualified applications. If the test result shows that the measuring device complies with the requirements of the OIML international recommendation, the issuing institution shall issue an OIML certificate that is approved by the International Legal System Metrology Committee and conforms to the international format and content, and then registers and informs the International Legal System and Measurement Bureau. Member States also publish in their publications. OIML certificates are universally recognized among member countries and have been widely recognized internationally. With the formulation and revision of international recommendations, the scope of certification has been extended to 28 kinds of measuring instruments. Non-automatic weighing instruments are one of the earliest measuring instruments to be certified. Electronic weighing scales and weighing instruments belong to the category of non-automatic weighing instruments. In China, the OIML test designated laboratory for non-automatic weighing instruments is the Qingdao Weighing Test Center and China Institute of Metrology. As an export company of weighing apparatus products in China, if you do not pay attention; if you do not apply in time, you will lose a lot of trade opportunities. The certificate of conformity of the measuring instrument OIML can not only promote international trade, but it can also be applied to the advertising of the measuring instrument to improve the brand image of the type measuring instrument.

The OIML certification of measuring instruments has become a common requirement in international trade. In recent years, more and more companies in China have paid attention to OIML certificates for measuring instruments. In the 1990s OIML awarded the first measuring instrument OIML to China. The certificate product is the electronic pricing scale. In recent years, China has more than a dozen specifications of electronic pricing scale passed the OIML test, and issued the OIML certificate. Now OIML China Secretariat has begun to accept the application of the OIML certificate system test for weighing instruments. In fact, in 1999 and 2001, China and the Netherlands NMI and the German PTB respectively conducted mutual recognition of non-automatic weighing instrument type test reports, and the test methods of non-automatic weighing instruments were consistent with international general standards. In addition, there are many conveniences for conducting tests in China, and the test fees are relatively cheap. It is believed that foreign companies will apply for OIML tests in the near future.

Although most of China's export-oriented scale enterprises have already taken note of the importance of OIML certificates for measuring instruments, some companies have rushed to apply for OIML certificates when they review their products in international trade. They want to take it within a week. To the certificate. As the OIML certification system test is a more rigorous test, the test basis for the non-automatic weighing instrument is the OIMLR76 international recommendation "non-automatic weighing instrument." The test period is long, and it takes at least several months from the time of application to the certificate. The type evaluation test of domestic new measuring instruments new products is different from the OIML certificate system test, and there is no distinction between OIML certificate system tests and domestic measurement instrument type evaluation tests. If weighing instruments of production companies are not sold domestically, they can apply for OIML certificates without applying for domestic manufacturing licenses. Although there are many similarities between the two test methods in the test project, the test basis for the two is different. The domestic type evaluation test is based on JJG555-96 “General Verification Regulations for Non-automatic Weighing Scales”; the OIML certificate system test is based on the international recommendations of OIMLR76 “Non-automatic Weighing Scales”. Some companies have already got it.

OIML certificate of conformity has been registered, but the OIML certificate has not been properly used in international trade, making the role of the certificate unclear. With the development of China's international trade, OIML certificate is increasingly important.

As a member of the WTO, China should abide by the WTO guidelines in international trade. The OIML certificate of metrology equipment is the guarantee and prerequisite for international trade of weighing companies in an equal environment. In order to avoid and eliminate technical barriers in the export of weighing instruments and to facilitate the expansion of exports of weighing instruments and products, exporters of weighing apparatus products should actively apply for OIML certificates.
