ISO 10333-3:2000

Overview

ISO 10333-3:2000 defines requirements, test methods, instructions for use and maintenance, and marking/packaging rules for self-retracting lifelines (SRLs) used in personal fall-arrest systems (PFAS). It covers SRLs - including those with an integral-rescue facility - that are anchored above the work place and intended for single-person use with a total mass ≤ 100 kg. The standard addresses design, lifeline materials and terminations, locking behaviour, dynamic and static performance tests, and information supplied with the product.

Key Topics and Requirements

• Scope and limits
  • SRLs as a connecting subsystem of PFAS; single-user limit of 100 kg total mass.
  • Exclusions: special environmental durability treatments are not prescribed and should follow other standards.
• Lifeline materials
  • Fibre ropes and webbing must be high-tenacity synthetic fibres; minimum breaking force for fibre/webbing 22 kN.
  • Wire rope minimum diameter 5 mm with minimum breaking force 15 kN.
  • Laid ropes must have at least three strands; braided ropes to comply with EN rope standards.
• Terminations and connectors
  • User-facing end must terminate with a swivel connector compliant with ISO 10333-5.
  • Eye splices and stitched webbing terminations have specific construction and inspection features (e.g., number of tucks, contrasting thread).
• Performance and testing
  • Tests include corrosion resistance (salt spray), locking tests after conditioning, locking reliability, retraction behaviour, dynamic performance at full extraction, static strength, plus lifting/lowering tests where an integral-rescue facility is provided.
  • Presence of fall indicators, energy absorbers integral to a lifeline, and minimum locking test mass are defined as terms.
• Information and marking
  • Requirements for instructions for use, maintenance, marking and packaging to ensure traceability and safe operation.

Applications and Practical Value

• Use ISO 10333-3 when specifying, procuring, certifying or manufacturing SRLs for working-at-height tasks (construction, maintenance, telecoms, wind energy, industrial access).
• Helps safety managers, PPE specifiers, procurement teams, and test laboratories ensure SRLs meet recognized safety and performance benchmarks.
• Useful for manufacturers to design SRLs (including integral-rescue features) that meet international test methods and user information requirements.
