IEC 61340-6-1:2018

Overview

IEC 61340-6-1:2018 - "Electrostatics - Part 6-1: Electrostatic control for healthcare - General requirements for facilities" specifies technical requirements and recommendations for controlling electrostatic phenomena in healthcare facilities (hospitals, care centres, clinics). The standard addresses hazards from electrostatic discharge (ESD), electrostatic attraction (ESA), ignition of flammable substances and electrostatic shocks, and sets out requirements for equipment, materials and operational controls used to manage static electricity. It specifically excludes medical electrical equipment covered by IEC 60601-1 and IVD equipment covered by IEC 61010‑2‑101.

Key topics and technical requirements

• Scope and terminology: Definitions for ESD, ESA, ESDS (electrostatic discharge sensitive devices), EPA (ESD protected area) and related terms.
• Electrostatic hazards: Identification of risks to patients, staff and equipment (instrumentation upset, contamination, ignition, shocks).
• Classification of medical locations: Rooms and procedures are classified (e.g., Group 0, Group 1, Group 2) where electrostatic control ranges from recommended to required depending on risk and activity.
• Electrostatic control requirements:
  • Administrative controls: design, operational responsibility, qualification, verification and acceptance testing.
  • Technical controls: electrical safety, material classification, selection of low-charging textiles, footwear and floor coverings, packaging and containers for electrostatic control.
  • Service and maintenance: ongoing checks and procedures to sustain control measures.
• Test methods and verification: Annex A provides test methods for low-charging textiles (clothing, bedding, surgical drapes); Annex B covers ionization and other considerations.
• Standards referenced: IEC 61340 series (measurement & test methods), IEC TR 61340-1, IEC 60364-7-710 (medical location electrical installations), ISO textile test methods and others.

Practical applications

• Design and retrofit of operating theatres, imaging suites and other critical medical areas where ESD can affect equipment or contamination-sensitive procedures.
• Specification and selection of flooring, garments, bedding, surgical drapes, footwear and ESD packaging used in healthcare facilities.
• Development of facility-level ESD control policies, acceptance tests, qualification and maintenance schedules.
• Risk mitigation where flammable substances or sensitive electronic assemblies are present.

Who should use this standard

• Hospital facility managers and architects
• Biomedical and clinical engineers
• EHS (Environment, Health & Safety) and infection control teams
• Procurement/specification writers for medical textiles, flooring and ESD products
• Manufacturers of ESD control materials and PPE supplying healthcare

Related standards (selection)

• IEC 61340-2-1, -2-3, -4-1, -4-3, -4-5 (electrostatics measurement & test methods)
• IEC TR 61340-1 (principles and measurements)
• IEC 60364-7-710 (electrical installations for medical locations)
• IEC 60601-1 and IEC 61010‑2‑101 (not covered - medical electrical/IVD equipment)
