No standard for naming test machines, increasing industry management costs

Definition of material testing machine according to the National Measuring Technical Specification of the People's Republic of China JJF1011-2006 "Terms and Definitions of Force Value and Hardness Measuring": Material testing machine is an equipment that tests mechanical properties and process performance on materials, parts and components.

How to name a wide variety of material testing machines? Traditionally, tensile testing machines used for metal material testing, conventionally omitted the word "metal" and are named tensile testing machines; while tensile testing machines used for non-metallic material testing will have the name of non-metallic material, such as rubber and plastic tensile testing machines. Therefore, the naming of the material testing machine is not uniform.

In the first-level classification catalog of national standards, the test machine is classified as instrumentation category (code N). Zhang Guiren pointed out that its model preparation method was based on ZB N 70001-1987 and later converted JB/T 10059-1999 "Testing Machine and Non-destructive Testing Instrument Model Preparation Method", which was also abolished on January 23, 2008. Since there are no relevant standards, the current test machine products are customized and named by the company.

Testing machine manufacturers evade national management to increase industry management costs. Zhang Guiren told the Instrument Information Network that in addition to implementing general technical requirements for GB/T2611-2007 test machines and general national and industry standards such as JB/T 6147-2007 "Technical Requirements for Packaging, Packaging Marking, Storage and Transportation of Testing Machines", the manufacturing and inspection of material test machines should also comply with the corresponding national metrology and verification regulations or calibration specifications. Material testing machines are metering instruments listed in the state for law management. However, due to the confusion of naming test machines in the market, many test machine products cannot apply for new product manufacturing licenses for metrology instruments. This is undoubtedly a practical problem facing the relevant metrology administrative department.

Generally speaking, traditional test machine manufacturers or enterprises formed by entrepreneurs from these companies are more accustomed to shaping and naming test machine products according to the original national regulations, and subjectively have the desire to obtain a metering instrument manufacturing license. Another part of the company prepares and namings products according to their own wishes based on actual conditions and market needs. On the one hand, it can facilitate the company's management of products, and on the other hand, it is to avoid the state's management of them.

"Although all model preparation methods and product naming are not correct or wrong in themselves, for a country, this undoubtedly greatly increases the management cost and difficulty of the test machine."

How test machine manufacturers seize the market's leading position Test machine products, whether they are tensile testing machines, universal testing machines, impact testing machines, and fatigue testing machines, the core technology is mainly reflected in the three parts of measurement components, control components and measurement and control software.

"The competitiveness of domestic and domestic test machine manufacturers is: whoever adopts new measurement components will improve the product level, and whoever adopts new test machine products will be the first to launch new test machine products to the market; similarly, whoever adopts new control components to improve control levels such as tensile speed, stress rate, strain rate, test frequency, test mode, etc. will gain the market's advantage."

In addition, "because the material testing machine involves a wide range of scientific and technological fields, such as high-temperature technology, low-temperature technology, vacuum technology, hydraulic technology, optical technology, electronic technology and laser technology, and various testing, recording and display instruments are also used, the development of material testing machines often depends on the level of many scientific and technological fields."

"Although the new processes and new technologies provided by society are keeping pace with the times, the degree to which different test machines adopt new processes and new technologies is proportional to the degree to which they are applied." Zhang Guiren said that test machines with high demand in society often have many competitors. The result of competition is that the more the test machine products are built, the better the product prices are, the cheaper the product prices are; the result of competition is that it promotes the development vitality of the test machine industry and increases users' choices.

Zhang Guiren told the Instrument Information Network that the country has adopted a policy of consistent support and encouragement for the test machine industry, and some regions will also provide certain tax incentives or rewards for scientific and technological innovation. However, these support policies can only be reflected in the later stages of enterprise development and economic benefits. The country's emphasis on product quality is the opportunity for the development of testing machines.
