DIN 72551 standard is a German standard that specifies the characteristics and requirements for low-tension single-core cables used in road vehicles. It covers the classification, identification, specifications, testing, and inspection of wires and cables for automotive wiring. It also provides guidance on the installation, maintenance, and repair of wires and cables.
DIN 72551 standard is important because it ensures the safety, reliability, performance, and durability of electrical connections in vehicles. It also helps you comply with international regulations and standards for automotive wiring. By following DIN 72551 standard, you can avoid potential hazards, faults, failures, and damages caused by poor quality or incompatible wires and cables.
The Benefits of DIN 72551 Standard for Automotive Wiring
Improved safety and reliability of electrical connections
Enhanced performance and durability of wires and cables
Another benefit of DIN 72551 standard is that it enhances the performance and durability of wires and cables in vehicles. By specifying the specifications and requirements for wires and cables, it ensures that they can deliver the optimal current, voltage, frequency, signal, or data transmission that they are designed for. It also ensures that they can last longer and function properly without losing their efficiency or quality over time.
Compliance with international regulations and standards
A third benefit of DIN 72551 standard is that it helps you comply with international regulations and standards for automotive wiring. By following DIN 72551 standard, you can ensure that your wires and cables meet the minimum requirements for safety, performance, quality, compatibility, interoperability, or conformity that are set by various authorities or organizations around the world. This can help you avoid legal issues, penalties, fines, or sanctions that may arise from non-compliance.
The Main Features of DIN 72551 Standard for Automotive Wiring
The classification and identification of wires and cables
One of the main features of DIN 72551 standard is that it provides a clear and consistent system for the classification and identification of wires and cables for automotive wiring. It defines six types of wires and cables based on their temperature range, voltage rating, cross-sectional area, insulation material, color code, or marking. These are:
Type A: Single-core PVC insulated cable with a temperature range of -40C to +85C
Type B: Single-core PVC insulated cable with a temperature range of -40C to +105C
Type C: Single-core PVC insulated cable with a temperature range of -40C to +125C
Type D: Single-core cross-linked polyolefin insulated cable with a temperature range of -40C to +125C
Type E: Single-core cross-linked polyolefin insulated cable with a temperature range of -40C to +150C
Type F: Single-core fluorinated polymer insulated cable with a temperature range of -40C to +200C
It also provides a standardized system for the color code or marking of wires and cables based on their function or circuit. For example:
Black: Ground or negative terminal
Brown: Tail light or parking light
Red: Battery positive terminal or ignition switch
Green: Turn signal or indicator light
Blue: High beam or headlight
Yellow: Low beam or headlight
White: Reverse light or backup light
Purple: Brake light or stop light
Orange: Hazard warning light or flasher light
Pink: Fuel gauge or fuel pump
Gray: Speedometer or tachometer
Turquoise: Oil pressure gauge or oil pressure switch
Violet: Temperature gauge or temperature sensor
Lilac: Generator or alternator
Slate: Starter motor or starter solenoid
Brown/white stripe: Horn or horn relay
Green/white stripe: Windshield wiper or windshield washer
Blue/white stripe: Radio or antenna
Yellow/white stripe: Air conditioner or heater fan
The specifications and requirements for wires and cables
Another main feature of DIN 72551 standard is that it provides detailed specifications and requirements for wires and cables for automotive wiring. It specifies the minimum and maximum values for various parameters such as cross-sectional area, insulation thickness, conductor resistance, insulation resistance, dielectric strength, tensile strength, elongation, bending radius, flammability, or thermal stability. It also specifies the methods and conditions for measuring or testing these parameters.
For example, DIN 72551 standard specifies that the cross-sectional area of wires and cables should be between 0.35 mm2 and 6 mm2, depending on the type and function of the wire or cable. It also specifies that the insulation thickness of wires and cables should be between 0.2 mm and 0.8 mm, depending on the type and temperature range of the wire or cable. It also specifies that the conductor resistance of wires and cables should not exceed 56.5 ohm/km for type A, 54.5 ohm/km for type B, 52 ohm/km for type C, 50 ohm/km for type D, 48 ohm/km for type E, or 46 ohm/km for type F.
The testing and inspection methods for wires and cables
A third main feature of DIN 72551 standard is that it provides standardized testing and inspection methods for wires and cables for automotive wiring. It describes the procedures and equipment for conducting various tests such as dimensional test, electrical test, mechanical test, thermal test, chemical test, or environmental test. It also describes the criteria and limits for accepting or rejecting wires and cables based on the test results.
For example, DIN 72551 standard describes how to conduct a dimensional test by measuring the cross-sectional area, insulation thickness, or outer diameter of wires and cables using a micrometer or a caliper. It also describes how to conduct an electrical test by measuring the conductor resistance, insulation resistance, or dielectric strength of wires and cables using a multimeter or a megger. It also describes how to conduct a mechanical test by measuring the tensile strength, elongation, or bending radius of wires and cables using a tensile tester or a mandrel.
