This Standard applies to the storage, transportation and packaging of products
that constitute communication network equipment (hereinafter referred to as
the products). It is general technical specifications to protect the product intact
and undamaged during transportation, loading-unloading, and storage.
1 General
1.1 Product packaging shall be designed according to the nature of the product
and the environmental conditions of storage and transportation. It is required to
be well-protected, compact, firm and reliable, economical and reasonable, and
beautiful. Ensure that the product will not be damaged due to packaging and
reduce product quality during the process of loading-unloading and
transportation and within the validity period of the storage.
1.2 Before the new product is put into production, it must have product
packaging standards and design documents that meet the requirements of this
Standard.
1.3 The product packaging specified in this Standard is valid for two years from
the date of packaging. During this period, the warehouse where the product is
stored shall be well ventilated. The indoor temperature is -10~+40°C. The
relative humidity is not greater than 75%. Acid, alkaline or other harmful gases
in the air shall meet the requirements of environmental protection regulations.
Packages that need to be moisture-proof shall be placed on a rack that is 30cm
above the ground and 40cm away from the wall.
1.4 In case of special circumstances, according to the specific requirements of
product storage and transportation, according to the agreement between the
supplier and the demander.
1.5 Matters not specified in this Standard shall be implemented in accordance

2.2.3.1 Products that have undergone moisture-proof treatment, to protect the
product from moisture damage during storage and transportation, according to
the structure of the product and the requirements of different storage and
transportation environments, are classified into primary moisture-proof
packaging and secondary moisture-proof packaging.
a. Primary moisture-proof packaging
Before packaging, the product shall be parked for 24h for pretreatment in an
environment with a temperature of 20°C and a relative humidity of 65%. Use
moisture-proof sealing material with low moisture permeability and appropriate
amount of moisture absorbent to seal the product for packaging operation. No
rust or mildew is allowed on the surface and inside of the packaged product
during the validity period of the package.
b. Secondary moisture-proof packaging
Use low-moisture-permeable moisture-proof sealing materials and suitable
moisture-absorbing agents to seal the product and carry out packaging
operations according to the requirements of 2.1.3. The surface of the packaged
product and its interior are not allowed to have traces of water vapor adherence
during the validity period of the package.
2.2.3.2 Moisture-proof materials shall have the following requirements
a. They have good water resistance. The moisture permeability shall be less
than 10g/m2•24h. Commonly used moisture-proof materials mainly include:
polyethylene film, aluminum-plastic composite film, wax impregnated paper,
moisture absorbent and so on.
b. All kinds of plastic film bags (containers) used for moisture-proof and airtight
packaging shall be intact, free from damage and pinholes. The moisture
permeability of the sealing part cannot be greater than the moisture
permeability of the material itself.
c. The moisture content of the moisture absorbent shall not exceed 4%.
2.2.4 Shockproof packaging
2.2.4.1 Shockproof packaging shall be used for products that are delicate,
sensitive, or fragile in structure. The shockproof package shall meet the
following requirements after the shockproof project test:
a. The structure of the packaging container shall be free of deformation and
functional damage.
b. There shall be no mechanical damage on the surface of the product and its
parts.
c. The various indicators of the product shall be within the tolerance and the
scope of the commissioning after commissioning.
2.2.4.2 According to the characteristics of the product, choose suitable
shockproof materials. Commonly used anti-bedding materials mainly include:
corrugated cardboard, expandable polystyrene foam, rubber, sponge, plastic
air cushion, polyurethane foam and springs.
2.2.5 Anti-rust packaging
2.2.5.1 For products that need anti-rust treatment and metal surfaces that are
easy to rust, anti-rust treatment shall be carried out in accordance with the
relevant provisions of product anti-rust treatment. There shall be no rust during
the validity period of the product packaging.
2.2.5.2 Anti-rust materials shall have the following requirements:
a. It shall have good adhesion to the metal surface, non-corrosive, and easy to
remove.
b. The commonly used anti-rust materials mainly include: neutral sodium
benzoate anti-rust paper, No. 19 anti-rust paper, 201 anti-rust grease and so
on.
2.2.6 Anti-mold packaging
2.2.6.1 For products that need anti-mildew treatment, anti-mildew packaging
shall be carried out.
2.2.6.2 Anti-mold materials shall have the following requirements:
