Article number and name of internal system

The standard

1. A commodity has two attributes: article number and name. Article number is the only and authoritative description of the goods.

2. Principles of commodity classification:

Level 1: material

Level 2: standards

Level 3: Specifications

The classification of the first and second levels is only catalog classification, which is equivalent to the meaning of folder, and the third level is the final product. It is strictly prohibited to create or generate final goods in the first and second classes.

3. Specification of material number name for these three grades:

The first level:

The article number The name of the
304 SUS304 stainless steel
316 SUS316 stainless steel
303 SUS303 stainless steel
410 SUS410 stainless iron

QT .

The last term, QT, means something else and is named “. Instead, raw materials, products without specific material properties, and relatively rare materials belong to this category, such as non-loose, various tools, red copper products, titanium products, etc. There are 15 items, that’s all. Write them down.

The article number is the standard number we use everyday

There are only 10 kinds with the year, because the products sold at present do have the year, other standards will be added if they meet the year.

If it is a standard product but there is no standard number, use Chinese as the article number

The article number is not allowed to have a space, and there is a space between the Chinese name and the standard number, and a space between the attributes of the name, the same as below.

There are many kinds of standards and the number is not increasing. The above is only an example. Please check the details in the system. The standard number needs to be noted down.

The third stage:

The article number The name of the instructions
M6*16 M6*16 Screw type
M6-1.25 – M6-1.25 – The tooth is apart from the special
A quarter – 20 * 3/8 A quarter – 20 * 3/8 American
M6 * 16 galvanized M6 * 16 galvanized A plating
M3-0 M3-0 Pressure riveting
440-2 440-2
3.5 M3-6 3.5 M3-6
M6*16P10010522 M6*16 P10010522 Bring customer material number
M3 * 6.35 * 3.01 M3 * 6.35 * 3.01 Custom products (round)
H6.35 * 3.01 H6.35 * 3.01 Custom products (hexagon without thread)
M3 * 4.5 * 9 M3 * 4.5 * 9 GB809 series
M3 * H4.75 * 16 + 6 M3 * H4.75 * 16 + 6 Yin and Yang are stud
M3 * H4.75 * 16 M3 * H4.75 * 16 Two-way stud
T321 T321 Simply only material number

Here the article number and name are completely consistent (except space)

Suffix description:

1 Suffixes are allowed here (level 3 classification), including product description and plating customer part number (multiple suffixes in this order).

2 no plating suffix default for the surface color (except pressure riveting, pressure riveting according to the industry default)

3 Other insufficient expression can be suffixed.
