ISO 10333-6:2004

Overview

ISO 10333-6:2004, "Personal fall-arrest systems - Part 6: System performance tests," specifies dynamic system-level tests and requirements for complete personal fall-arrest systems (PFAS). It applies to PFAS assembled from components and subsystems that conform to other parts of ISO 10333 and ISO 14567. The standard uses a rigid-torso test mass to simulate a faller, defines acceptable arresting forces and free-space considerations, and gives examples of how components may be combined into a tested PFAS.

Key topics and requirements

• Scope and limits
  • Applies to single-person PFAS with a total mass ≤ 100 kg.
  • When activated, PFAS must limit peak arresting force to 6 kN maximum.
  • Excludes systems using waist belts or chest harnesses as sole body-holding, lanyards without energy absorbers, and equipment for material lifting.
• System-level testing emphasis
  • Specifies tests for complete assembled systems (not just individual components) to reveal interactive performance issues that component tests can miss.
  • Uses a rigid torso surrogate and defined test apparatus and procedures for different PFAS configurations.
• Designation and codes
  • Provides a code system to designate PFAS configurations (e.g., A + EAL + FBH for anchor + energy-absorbing lanyard + full-body harness).
• Manufacturer and assembler responsibilities
  • Components/subsystems must comply with the relevant ISO parts.
  • Manufacturers should supply compatibility information; assemblers must ensure combinations are proven compatible.
• Performance test types
  • Test methods cover PFAS based on energy-absorbing lanyards, self-retracting lifelines, temporary/permanent vertical lifelines, and vertical rails.
• Additional guidance
  • Annex A addresses design, ergonomics and required free space under a user to prevent collisions.

Applications

ISO 10333-6 is practical for:

• Verifying dynamic performance and compatibility of assembled PFAS used for work at height.
• Detecting unforeseen interactions between harnesses, connectors, lanyards, SRLs, and anchor devices.
• Supporting procurement, product certification, and safety validation where complete-system behavior must be demonstrated.

Who uses this standard

• Manufacturers and assemblers of fall-arrest equipment
• Test laboratories and certification bodies
• Safety managers, specifiers, and procurement teams in construction, utilities, maintenance, and industrial works at height
• Designers of anchor systems and fall-protection programs

Related standards

• ISO 10333 series: Part 1 (Full‑body harnesses) through Part 5 (Connectors)
• ISO 14567 (Single-point anchor devices)
• ISO 9000 (quality management guidance referenced)
