1、 Product standards:
This product is produced according to GB/T 12706.1-2002 or IEC 60502 standards, and can also be produced according to other standards requested by users.
In addition to the above standards, flame retardant cables are classified into three different flame retardant categories: A, B, and C according to the GB/T18380.3-2001 standard. The flame retardant performance of Class A is excellent, and users can choose according to their needs.
The fire resistance performance of fire-resistant cables should comply with GB/119216.21-2003.
Halogen free low smoke flame-retardant cables are produced according to enterprise standards. The flame retardant performance is divided into different flame retardant categories A, B, and C according to the GB/T18380.3-2001 standard. The smoke concentration passes the test specified in GB/T17651-1998, and the pH value and conductivity should comply with the provisions of GB/T17650.2-1998.
