EN IEC 60227 Polyvinyl Chloride Insulated Cables with Nominal Voltages Up to and Included 450/750 V

The standard “EN IEC 60227 Polyvinyl chloride insulated cables with nominal voltages up to and including 450/750 V”, which is based on a European standard and subsequently published by the International Electrotechnical Commission (IEC), consists of the following sub-sections published under the same title:

• The standard “EN IEC 60227-1 Part 1: General requirements” applies to rigid and flexible cables with polyvinyl chloride-based insulation and, if applicable, sheathing, used in power installations with a nominal voltage up to 450/750 V and not exceeding 450/750 V AC. The term cord is used for some types of flexible cables.

Cable types are specified in the EN IEC 60227-3, EN IEC 60227-4, EN IEC 60227-5, EN IEC 60227-6, and EN IEC 60227-7 standards. The code definitions for these cable types are included in these standards.

The test methods specified in this standard are given in other sections of this standard, in the relevant sections of the IEC 63294, IEC 60332-1-2 and IEC 60811 standard series.

• The standard “EN IEC 60227-2 Part 2: Test methods” describes the methods for performing the tests specified in all parts of the EN IEC 60227 standard. The IEC 63294 standard, which essentially replaces this standard, defines the following test methods.
• Electrical testing methods
• Electrical resistance of conductors
• Tension test performed on completed cables.
• Tension test on blood vessels underwater
• Insulation resistance
• Insulation resistance at temperatures above 90 degrees.
• Long-term resistance of insulation to direct current.
• No defects in insulation.
• Surface resistance of the case
• Non-electrical testing methods
• Checking the durability of colors and markings.
• Measuring insulation thickness
• Measuring the sheath thickness
• Measuring overall dimensions and ovality.
• Solderability test for untinned conductors.
• Stretch test
• Static flexibility test
• bending test
• Wear resistance test
• Drop test
• Space
• Three-pulley stretching test
• Curl test
• Testing of mechanical properties of rubber compound insulation after aging in an air oven.
• Heat resistance testing of textile weaves
• Case water resistance test
• Chemical test: Determination of halogens - Elemental test
• The standard “EN IEC 60227-3 Part 3: Unsheathed cables for fixed wiring” details specific standards for single-core unsheathed cables with polyvinyl chloride insulation for fixed wiring at nominal voltages up to 450/750 V. This standard provides specific requirements for unsheathed cables for fixed wiring in addition to the applicable requirements specified in the IEC 60227-1 standard, which applies to all cables. Test methods for cables specified in the IEC 60227 series of standards are included in the IEC 63294 standard.
• The standard “EN IEC 60227-4 Part 4: Sheathed cables for fixed wiring” details the specifications for lightweight polyvinyl chloride sheathed cables with a nominal voltage of 300/500 V. In addition to the relevant requirements specified in the IEC 60227-1 standard, which applies to all cables, this standard provides specific requirements for sheathed cables for fixed wiring. Test methods for cables specified in the IEC 60227 series of standards are included in the IEC 63294 standard.
• The standard “EN IEC 60227-5 Part 5: Flexible cables (cords)” details the characteristics of flexible cables (cords) with polyvinyl chloride insulation and nominal voltages up to 300/500 V. In addition to the relevant requirements specified in the IEC 60227-1 standard, which applies to all cables, this standard provides specific requirements applicable to flexible cables (cords). Test methods for cables specified in the IEC 60227 series of standards are included in the IEC 63294 standard.
• The standard “EN IEC 60227-6 Part 6: Elevator cables and flexible connection cables” details the specific technical specifications for both circular and straight elevator cables and flexible connection cables with rated voltages up to 450/750 V. Each cable must comply with this standard and the relevant requirements given in the IEC 60227-1 standard.
• The standard “EN IEC 60227-7 Part 7: Flexible cables with two or more conductors and with rated voltages up to and including 300/500 V, shielded and unshielded” details the specific technical requirements for polyvinyl chloride insulated, shielded and unshielded control cables with rated voltages up to 300/500 V. This standard provides specific requirements for shielded and unshielded control cables with rated voltages up to 300/500 V, in addition to the relevant requirements specified in the IEC 60227-1 standard, which applies to all cables. Tests for cables specified in the IEC 60227 series of standards are covered in the IEC 63294 standard.

In short, the EN IEC 60227 series of standards is an international standard that defines the requirements for polyvinyl chloride (PVC) insulated cables with nominal voltages up to 450/750 V. It is one of the most widely referenced standards worldwide for flexible and fixed-installation low-voltage power cables used in domestic, commercial, and light industrial applications. These standards have formed the backbone of low-voltage PVC cable standardization for many years.

The EN IEC 60227 series of standards is considered important in practice and globally for the following fundamental reasons:

• It ensures electrical safety worldwide: It defines minimum performance and safety requirements (insulation thickness, voltage withstand, heat resistance, flame retardancy) for the most common low-voltage cables (up to 450/750 V). Without these standards, cables can overheat, cause electric shock, or ignite a fire.
• The most widely used cable standard in the world: This standard set is still the legal or commercial reference in over 100 non-European countries. Billions of meters of flexible PVC cable conforming to this standard are manufactured and installed every year.
• The universal language of trade for cables: Every manufacturer in the world knows exactly which cable is needed the moment they see this standard; no further explanation is required.
• The basis of national standards: Numerous countries have adopted the IEC 60227 standard with few or no modifications. This ensures significant economies of scale and consistent quality across continents.
• Compatibility and interoperability: According to this standard, a cable manufactured in one country is electrically and mechanically identical to a cable manufactured in another country. Electricians can use the same cable types and termination applications everywhere.
• Long-term reliability: This standard continues to evolve. Cables meeting this standard have a proven service life of 20-30 years under normal conditions, which is critical for concealed fixed cabling in homes and buildings.
