IEC 60895:2020

Overview

IEC 60895:2020 is an international standard developed by the International Electrotechnical Commission (IEC) focusing on conductive clothing for live working on electrical installations. This standard specifies requirements and tests for conductive garments and their component parts, designed to ensure electrical safety when working live on AC and DC electrical systems with nominal voltages up to 1000 kV AC and ±800 kV DC.

The conductive clothing covered includes jackets, trousers, coveralls, gloves, hoods, helmets, shoes, boots, and socks, providing electrical continuity throughout the clothing and reducing the electric field inside the wearer's protective gear. The 2020 edition is a technical revision of the previous 2002 standard and introduces several key updates and classifications to enhance safety, durability, and usability.

Key Topics

• Scope & Application
  IEC 60895:2020 applies to conductive clothing worn primarily for bare-hand live working on high-voltage AC and DC electrical installations. It mandates electrical continuity across garment components and effectively reduces electric field exposure to the wearer.

• Classes of Conductive Clothing
  Two classes of conductive clothing with distinct electrical requirements were introduced, allowing users to select appropriate protection levels based on the voltage and working conditions.

• Electrical & Mechanical Requirements
  The standard sets detailed criteria for:

  • Electrical resistance of garment materials and individual components to ensure proper conductivity.
  • Shielding efficiency to protect against electric fields.
  • Mechanical strength including tear resistance, burst strength, and abrasion resistance for outer layer materials.
  • Flame retardancy to enhance wearer's protection in hazardous environments.
  • Durability including cleaning resistance and tests for spark-discharge protection.

• Testing Procedures
  IEC 60895 specifies comprehensive test methods including:

  • Type tests for materials and garment assemblies.
  • Methods for measuring electrical resistance, current-carrying capability, and shielding efficiency.
  • Mechanical tests to validate fabric strength and durability.
  • Periodic non-destructive testing recommendations for in-service inspections.

• Component Parts Requirements
  The standard covers various component parts such as gloves, helmets, face screens, shoes, socks, and scarves, ensuring each part maintains electrical continuity and safety compliance.

• Marking and Instructions
  Clear marking requirements and instructions for use aim to inform users about conductive clothing class, care, limitations, and proper wearing procedures.

• Safety Considerations
  While IEC 60895 ensures electric field protection and continuity, it explicitly does not guarantee protection against electric arc effects. Users must combine conductive clothing with other arc-protective gear as necessary.

Applications

IEC 60895:2020 is critical for professionals involved in:

• Live electrical work on high voltage systems including power distribution, transmission lines, and substations.
• Maintenance and repair operations on energized AC/DC electrical installations up to 1000 kV AC and ±800 kV DC.
• Electric utilities and industrial sectors where bare-hand live working is carried out, requiring reliable conductive garments to enhance operator safety.
• Design and manufacture of live working personal protective equipment (PPE) including conductive clothing and accessories.
• Regulatory bodies and safety managers developing workplace electrical safety programs and specifying PPE standards.

The standard helps minimize electrical hazards by controlling current flow paths through clothing and protecting the wearer from high electric fields encountered during live work, fostering safer working environments globally.

Related Standards

To ensure comprehensive electrical safety, IEC 60895:2020 should be used alongside:

• IEC 61482 series – Protective clothing against the thermal hazards of electric arcs.
• IEC 61111 – Live working gloves for electrical protection.
• IEC 61318 – Classification of defects in electrical insulation and equipment.
• IEC 60335 – Safety of household and similar electrical appliances (for related electrical safety criteria).
• IEEE and national standards for live working and electrical PPE practices.

Users should ensure compatibility between protective clothing elements and arc-resistant gear to achieve holistic worker protection from electrical hazards.
