Research on the disordered phenomenon of manual tool brands in China

in the past two years, there have been a large number of new tool brands in China, coupled with some tools without brands, the market is extremely chaotic. There are a large number of "three noes" products without origin, standards and certification; At the same time, there are many standards and certifications, which are difficult for ordinary consumers to distinguish. Ivebor tool believes that the products produced by negative enterprises must meet the standards and be responsible for consumers and themselves. For this reason, here is a brief introduction to the basic standards of conventional manual tools. The following is a brief introduction to the national standards of several commonly used countries

iso: International Organization for Standardization (ISO for short), the world's largest non-governmental specialized agency for standardization, is a very important organization in the field of international standardization. The task of ISO is to promote standardization and related activities on a global scale, so as to facilitate the exchange of international products and services, and to develop international cooperation in the Department of knowledge, scientific equipment and industry, which will thoroughly implement the spirit of the 109 CPC National Congress, technology and economic activities. It shows strong vitality and attracts more and more countries to participate in its activities

the content of the standard covers a wide range, from basic fasteners, bearings, various raw materials to semi-finished products and finished products, and its technical fields include information technology, transportation, agriculture, health care and environment. Each working organization has its own work plan, which lists the standard items (test methods, terminology, specifications, performance requirements, etc.) that need to be formulated. We are very familiar with the management label: ISO9001 quality system certification is here

China: national standards refer to the standards approved and issued by the national standardization authority, which are of great significance to the national economic and Technological Development and are unified throughout the country. National standards are unified technical requirements throughout the country. The standardization administrative department of the State Council prepares plans, coordinates the division of labor of projects, organizes the formulation (including revision), and uniformly approves, numbers and issues them. Where the law has other provisions on the formulation of national standards, the provisions of the law shall prevail. The service life of national standards is generally 5 years. After that, national standards will be revised or reformulated. In addition, with the development of society, the state needs to formulate new standards to meet the needs of people's production and life. Therefore, standards are dynamic information. GB: strong and perpendicular to the axis of the sample, digital display full-automatic impact testing machine generates signal system national standard through too high-speed load measurement sensor; Gb/t recommended national standard; Gb/z: national standard guidance technical document

United States: there are many ANSI steel standards, mainly including the following:

code name

ANSI American National Standard

AISI American Iron and Steel Institute Standard

ASTM American Society for testing and materials standard

ASME American Society of mechanical engineers Standard

ANSI: the American National Standards Institute is a non-profit non-governmental standardization organization and the center of American national standardization activities. Many American Institute of standardization standard preparation and revision are associated with it. ANSI approved standards have become American national standards, However, it does not formulate standards by itself. The standards are formulated by the corresponding standardization groups, technical groups, industry associations and organizations that voluntarily submit the standards to ANSI for approval. At the same time, ANSI plays a coordinating role between the federal government and civil standard systems to guide national standardization activities. Each association has its own standards and standard numbers. For example, our tool industry mainly uses ASME (American Society of mechanical engineers standard)

Germany: DIN (German Society for standardization and chemistry for short)

DIN is a German industrial standard. At present, din's standards almost involve construction engineering, mining, metallurgy, chemical industry, electrician, safety technology, environmental protection, health, fire protection, transportation, housekeeping and other fields. By the end of 1998, 25000 standards had been formulated and issued, and about 1500 standards had been formulated every year. More than 80% of them have been adopted by European countries

Japan: JIS

Japanese industrial standard (JIS) is the most important and authoritative national standard in Japan. Formulated by JISC

jis corresponding code: a-civil engineering and architecture; B-General machinery; C electrical and electronic; D-automobile; E-railway; F-ship; G-steel; H-non ferrous metal; K-chemistry; L-fiber; Brands can plan m-mines from insqin cooperative manufacturers; P-pulp, paper; Q-Management system; R-furnace industry; S-daily necessities; T-medical safety appliances; W-aviation; X-information processing; Z-other

France: nf

nf is the code of French standards, and its management organization is the French Association for Standardization (AFNOR)

afnor: a national standardization organization established in accordance with French civil law and recognized and funded by the government. Founded in 1926. On May 24, 1941, the French government issued a decree confirming AFNOR as the national standardization authority. Under the leadership of the standardization department of the government standardization management organization, AFNOR organized and coordinated the national standardization work according to the instructions of the government, and participated in the activities of international and regional standardization institutions on behalf of France. Headquartered in Paris, the capital. There are more than 6000 members, mainly group members and a small number of individual members

UK: bs

britishstandardsinstitution (BSI) is the first national standardization organization in the world. Non profit civil society recognized and supported by the British government. Founded in 1901, it is headquartered in London. At present, there are more than 20000 donation members and more than 20000 committee members.

in March 1903, Britain formulated the world's first national standard British Standard Specification (BSS) rolled steel section
