What is IEC 62821-1 - General requirements of electric cables 450/750 v about?
Electric cables are designed for various applications ranging from transmission to industrial use and they come in more than twenty varieties. IEC 62821-1 applies to cables with insulation, and sheath if any, based on halogen-free, thermoplastic compound, and having low emission of smoke and corrosive gases when exposed to fire, of rated voltages U0/U up to and including 450/750 V used in power installations of nominal voltage not exceeding 450/750 V a.c.
The test methods specified in IEC 62821-1 and in IEC 628213 are given in IEC 602272, IEC 6033212, IEC 606842, IEC 607541 and IEC 607542, and in the relevant parts of IEC 60811, and in IEC 610342 and in IEC 628212.
NOTE: For some types of flexible cable the term "cord" is used. The particular types of flexible cables are specified in IEC 628213. The code designations of these types of cables are given in Annex A.
Who is IEC 62821-1 -General requirements of electric cables 450/750 v for?
IEC 62821-1 on general requirements of electric cables 450/750 v is useful for:
- Manufacturers of electrical and electronic equipment
- Quality control teams
- Telecommunication operators
- Maintenance teams
Why should you use IEC 62821-1- General requirements of electric cables 450/750 v?
Electric cables enable the transfer of electrical signals from one device to the other. The core of the cable is protected by a flexible plastic jacket for safety. IEC 62821-1 provides general requirements of electric cables. These include:
- Indication of origin and cable identification
- Continuity of marks
- Durability
- Legibility
- Core identification by colours
- Core identification by numbers
- Conductors
- Insulation
- Filler
- Extruded inner covering
- Sheath
- Tests on completed cables
The guidelines in IEC 62821-1 help you check the quality of electric cables based on their general requirements, so that end customers can use superior quality products.
