Overview
EN 14975:2006+A1:2010 (CEN) - "Loft ladders - Requirements, marking and testing" is the European standard that defines terminology, product requirements and test methods for loft ladders intended to provide access to lofts or similar elevated spaces. It covers functional dimensions, construction and performance limits, marking and user instructions, and required mechanical tests to substantiate safety and durability. The standard is binding for CEN member states and is aimed at single-person loft ladder designs with a maximum total load of 150 kg.
Key topics and technical requirements
- Terms & types: Defines loft ladder types (concertina, hinged/folding, sliding - push-out and pull-out) and component names (stile, rung, tread, handrail, trapdoor, hinge, locking device).
- Maximum load: Designed for one person; maximum total load = 150 kg.
- Functional dimensions & angles: Prescribes key dimensions and climbing angles - for rungs: 60°–80°, for treads: 60°–75°, plus minimum widths, pitches and clearances.
- Construction features: Requirements for bearing surfaces, anti-slip surfaces, handrail provision (required when stile depth > 76 mm), feet, sharp edges, insulation/sealing and operability (stowing/un-stowing).
- Marking & instructions: Includes marking and user instruction requirements (standard defines what must be provided; see full text for specifics).
- Test methods and tolerances:
- General test conditions: room temperature 15–25 °C; measurement tolerances e.g. ±1 mm (linear), ±1° (angle), ±1% for static forces.
- Static load test: pre-load 1 000 N, then test force 2 600 N on designated rungs/treads; limits on permanent deformation (sliding/folding ≤ 0.005 × extended stile length).
- Fatigue test: cyclic load 1 500 N applied 5 000 times; residual deflection ≤ 20 mm/m.
- Torsion of rungs/treads: torque 50 N·m applied; permanent deformation ≤ ±1°.
- Handrail test: specified outward/downward loads (outward A/B/C = 100 N, downward D = 500 N, static F = 400 N); permanent deflection limits ≤ 15 mm.
- Rungs/treads bending: vertical force 2 600 N, max permanent deflection ≤ 3 mm.
- Ladder stops test for pull-out sliding ladders: repeated drop/arrest procedure to check stops and engagement.
Applications
- Use this standard when designing, manufacturing, testing, certifying or specifying loft ladders for residential and light commercial buildings.
- Practical uses include product development, quality control, third‑party testing, conformity assessment, procurement specifications, and building code compliance verification.
Who should use EN 14975
- Manufacturers and designers of loft ladders
- Test laboratories and conformity assessors
- Installers, architects, specifiers and building safety inspectors
- Procurement teams and regulators requiring compliant loft ladders
