Learn About CE EN1891 For Low Stretch Kernmantel Ropes

EN 1891 is a European standard that specifies safety requirements and test methods for low stretch kernmantle ropes used in rope access, rescue, and other work-at-height or fall protection systems. It is widely referenced in industries like rope access, rescue services, and caving, where controlled rope descents and ascents are performed.


🔍 What is EN 1891?

EN 1891:1998 is titled:

“Personal protective equipment for the prevention of falls from a height – Low stretch kernmantel ropes.”

It applies to low stretch kernmantle ropes, which have a core (kern) made of fibers providing most of the rope’s strength, and a sheath (mantle) that protects the core.


🧵 Products Applicable to EN 1891

Ropes conforming to EN 1891 are primarily used in:

  • Rope access work (industrial climbing)
  • Rescue operations
  • Caving and speleology
  • Work positioning systems
  • Fall protection backup systems (not primary fall arrest)
  • Tree climbing (arboriculture)

They are not dynamic ropes and should not be used for climbing falls.


🧪 Testing and Requirements of EN 1891

EN 1891 defines two rope types:

TypeDiameter (mm)Intended Use
Type A≥10.5 mm and ≤12.0 mmMain working lines, rescue, positioning
Type B≥8.5 mm and <10.5 mmLight-duty tasks, limited use, requires higher skill

Main Testing Criteria

Test/RequirementDetails
Sheath Slippage≤20 mm after testing
Knotability (Flexibility)Must allow tying of common knots (e.g., figure-8)
Shrinkage in Water<5% length shrinkage after immersion
Impact Force Test (Dynamic strength)Type A: Arrest 5 falls with 100 kg; Type B: 5 falls with 80 kg
Static StrengthType A: ≥22 kN; Type B: ≥18 kN (unaged rope)
Static Elongation under Load<5% elongation at 150 kg load
Fall Arrest PerformanceRope must not break or allow excessive fall distance
Sheath Slippage Under TensionMust not exceed threshold values under load cycles
Abrasion ResistanceMust survive a number of abrasion cycles with minimal wear
Thermal ResistanceMaintains integrity up to 150°C under load

📦 Labeling Requirements

Ropes must be permanently labeled (or come with labels) including:

  • Manufacturer name/trademark
  • Year of manufacture
  • Type (A or B)
  • Diameter
  • Standard (EN 1891)
  • CE mark
  • Unique identification number (for traceability)

🧾 Additional Notes

  • EN 1891 ropes are semi-static – they stretch under load, but not as much as dynamic climbing ropes.
  • The CE mark under EN 1891 implies that the rope has passed third-party conformity assessment (typically by a notified body).
  • Regular inspection and retirement criteria (e.g., cuts, glazing, sheath damage) are essential to maintain compliance.
