●   Definition and Technical Advantages of Powder Metallurgy
●   Powder metallurgy is a manufacturing process in which metal powders (or mixtures of metal and non-metal powders) are used as raw materials to produce metallic materials, composite materials, and various types of finished products through forming and sintering.
●   Advantages of powder metallurgy:
1. The capability to produce materials with special properties that cannot be obtained through conventional smelting methods: ① control of porosity in the final product (e.g., porous materials and porous oil-impregnated bearings); ② exploitation of synergistic effects arising from combinations of metals with each other or with nonmetals to produce materials with tailored properties (e.g., tungsten–copper pseudo-alloys for electrical contact materials, and friction materials composed of metal–nonmetal composites); ③ production of a wide range of composite materials.
2. Certain materials produced by powder metallurgy exhibit superior performance compared with those made by conventional melting processes: ① High-alloy powder-metallurgy materials outperform their cast counterparts (e.g., powdered high-speed steel can eliminate compositional segregation); ② The production of refractory metal materials or components generally relies on powder metallurgy (e.g., tungsten, molybdenum, and niobium).

About Introduction to DIN Standards

● DIN History and Current Situation
  Definition of DIN:

DIN is an association headquartered in Berlin, jointly established by its member organizations (registered as DIN e.V., founded in 1917). In Germany, DIN undertakes standardization activities and represents German interests within European and international standardization bodies. These responsibilities of DIN were formally defined in an agreement signed with the German government in 1975.

DIN is a round table where producers, traders, consumers, artisans, public-service providers, scientists, technical supervisors, and the state—indeed, anyone with an interest in standardization—sit together to exchange information on the state of technology and to codify new consensus into German Standards (DIN).
D IN   History and Current Situation

The Normenausschuss der deutschen Industrie (NADI), established on December 22, 1917, is the German Industrial Standards Committee.
The first DIN standard, the tapered pin standard, was published in January 1918.
In 1920, it was officially registered with the government authorities, and DIN was also registered as a trademark with the Patent Office.

In 1922, paper size standards were issued—A4.

In 1924, the DEUTH publishing house was established in collaboration with the German Federation of Industry to promote standardization. In 1926, NADI was renamed DNA, which stands for the German Standards Committee.
More than 3,000 standards had been published by 1927.
In 1943, the DIN headquarters was ultimately destroyed in a World War II air raid.
In 1946, with the approval of the Allied Occupation Authorities, DIN resumed full operations.
In 1951, DIN became a member of ISO, representing the entire German nation. Prior to 1954, the German Democratic Republic established the AFS Standardization Bureau, whose head was the Vice President of DIN.
In 1961, DIN, as a founding member of the European standardization organization, joined CEN; at the same time, East Germany closed all of DIN’s offices in the GDR.

In 1975, DNA formally signed an agreement with the German government, thereby defining the relationship between DNA and the government, and DNA was officially renamed DIN.

In 1979, DIN established a formal cooperative relationship with the Chinese Standards Organization.

On July 3, 2000, a joint research report commissioned by DIN and the German Federal Ministry for Economic Affairs was completed, revealing that the annual total national economic benefit generated through the application of DIN standards in Germany amounts to DM 30 billion.
Today's DIN has 76 standards committees and 5 specialized committees, which in turn oversee 3,300 working committees, as well as six specialized operating companies.

Eighty-five percent of DIN’s standardization outputs have been adopted by today’s CEN and ISO, and DIN also undertakes approximately one-third of CEN’s workload.
Sixty-five percent of DIN’s funding comes from the sale of standards, with the remainder derived from membership fees, corporate and societal donations, and a small amount of public funding allocated to occupational safety.

Types and Numbering System of DIN Standards 〇 Standard Type:

- Draft standard (Entwuerf)
●   For example ∶ EDIN 4701
Trial Operation Standards ( Pre-standard)
●   For example ∶VDIN 4701
Formal standard ( Norm)

●   For example :DIN 4701

Standard Numbering Method :

- General standard: DIN + standard serial number + year-month number

For example :DIN 4701:1999-02
- Adopted CEN/ISO standards
●   DIN EN 4701—Standard Adopting the European Standard
●   DIN EN ISO 4701—Adoption of European and International Standards
●   DIN ISO 4701—Standard Adopting an International Standard

Classification and Retrieval of DIN Standards  
Classification of DIN standards:

- DK—German Classification Number
-UDC—Universal Decimal Classification
-IPK (IPC) — International Patent Classification
-ICS—International (Standard) Classification Number

- ICS_International (Standard) Classification Number

—In 1991, ISO developed the International Classification for Standards, primarily for the classification, cataloging, ordering, and database construction of international standardization documentation.
—The ICS is a hierarchical classification system comprising three levels. The first level encompasses 40 standardized fields of specialization, each of which is further subdivided into 407 groups (second-level categories). Of these 407 second-level categories, 134 are in turn further disaggregated into 896 subgroups (third-level categories). The International Standard Classification employs a numerical coding scheme: two-digit codes are used for the first and third levels, while three-digit codes are assigned to the second level; consecutive levels are separated by a solid dot.
