Date：2021/5/31　　Clicks：1209

Wires and cables belong to the first batch of compulsory certification products, and all products listed in the compulsory product certification catalog must be certified by the certification body designated by the state, and the relevant certificates and certification marks can be applied before they can be sold. Import and use in business activities. Wire and cable products are as follows:

-Wire assembly
-Rubber insulated cables with rated voltages up to and including 450/750V
-Rubber insulated cords and cables with rated voltages up to and including 450/750V
-PVC insulated cables with rated voltages up to and including 450/750V

-PVC insulated cables, wires and cords with rated voltages up to and including 450/750V

The product units are divided as follows:
1. Polyvinyl chloride insulated cables with rated voltages up to and including 450/750V
  Voltage levels are: 300/300V 300/500V 450/750V

  Executive standard: GB5023.1~.7

2. Polyvinyl chloride insulated cables, wires and cords with rated voltages up to and including 450/750V
 The voltage levels are: 300/300V, 300/500V, 450/750V.

 Executive standard: JB8734.1~.5

3. Rubber insulated cables with rated voltages of 450/750V and below
  Voltage levels are: 300/300V 300/500V 450/750V

  Executive standard: GB/T 5013.1~8

4. Polyvinyl chloride insulated cables, wires and flexible cords with rated voltages up to and including 450/750V
 Voltage levels are: 300/300V 300/500V 450/750V

 Executive standard: JB/T 8735.1~3

5. Unit name: Cables and wires for rail transit vehicles
 Model: DCEH, WDZ-DCYJ, WDZ-DCYJB
 Standard number: GB/T 12528


6. Unit name: wire assembly
 Executive standard: GB 15934
 Plug-wire and cable-connector

 Among them, plugs, wires and cables should meet their respective product certification standards.

Attention issues:
a. The implementation of aluminum wires must be industry standards, and the wires of national standard products are all copper conductors;
b. If there are -IEC- letters in the model, the implementation must be the national standard; in the industry standard, the letter of the model is Pinyin;
c. The unequal cross-section cable in the rubber wire (such as three large and one small structure) must be the industry standard;
d. The product categories that implement CCC certification and production license are different, independent of each other, and do not conflict at present, but products that implement license management can apply for CQC mark certification (also called voluntary certification);
e. There are about 88 product models and series of CCC certification with nearly 1,000 specifications. The products are simple and complex. Please consult the relevant quality inspection agencies for technical issues.

About wire and cable CCC certification (typical case)
60227 IEC52 (RVV) 300/300V 2~3×0.5-0.75
60227 IEC53 (RVV) 300/500V 2~5×0.75-2.5

a. Test standard:
GB/T 5023.2-2008 (IEC60227-5:2003)
Supplementary requirements for JB/T 8734.3-2012 and PVC insulated flexible cables

b. Testing equipment that the factory should have:
-DC resistance bridge
-Spark test machine
- Pressure tester
- micrometer
-Vernier calipers
- projector

c. Identification content (ink or embossing can be used)
-Cable identification: manufacturer name (or trademark or logo) + product model + rated voltage
-Marking continuity: the distance from the end of a complete mark to the beginning of the next mark.
Mark on the sheath: ≤ 550mm
Mark on the insulation layer (without sheath): ≤ 275mm

d. Validity period of the certificate: 5 years. The factory is inspected once a year.
