Overview
EN 13538-2:2002 (CEN) defines a harmonized European test method for measuring the thickness and elastic recovery of sleeping bags filled with feathers and/or down. It is part of the EN 13538 series covering dimensional characteristics of sleeping bags and is intended for use by manufacturers, testing laboratories and compliance bodies involved in camping and outdoor equipment.
Key topics and technical requirements
- Scope: Method for determining sleeping bag thickness under a small preload and the elastic recovery after compression (feather/down filled products).
- Conditioning: Test specimens must be conditioned in accordance with EN 20139 - at least 12 hours at (20 ± 2) °C and (65 ± 5) % relative humidity.
- Apparatus:
- Rigid, flat reference surface large enough for the sleeping bag.
- Circular rigid indentor with area (800 ± 8) cm², counterbalanced for indifferent equilibrium.
- Measuring device with 0.1 mm graduations.
- Additional masses to apply pressures of (5 ± 0.1) Pa, (30 ± 0.1) Pa and (300 ± 1) Pa.
- Stopwatch (resolution ≥ 1 s).
- Thickness measurement:
- Apply a uniform pressure of (5 ± 1) Pa with the indentor.
- Measure distance between indentor and reference surface after (10 ± 1) s.
- Take readings (accuracy 0.1 mm) at the top and bottom and on at least six locations (repeat on at least 5 other areas).
- Elastic recovery measurement:
- Compress to 300 Pa for (60 ± 1) s, reduce to 30 Pa and record thickness after (10 ± 1) s, then reduce to 5 Pa and record thickness.
- Repeat measurements at positions at least 600 mm apart.
- Calculation: Elastic recovery is expressed as the percentage difference between the thickness at 5 Pa (after recovery) and the thickness at 30 Pa (after compression), referred to the 5 Pa thickness.
- Reporting: Include standard reference, test date/place, sample identification, mean thickness (to 0.1 mm), mean elastic recovery (rounded to nearest unit) and any deviations from the standard.
Applications and who uses it
- Sleeping bag manufacturers for product development, quality control and specification verification.
- Independent testing laboratories and certification bodies performing compliance and performance testing.
- Procurement managers and retailers assessing product claims for insulation loft and recovery (important for thermal performance and packability).
- R&D teams comparing fill materials (feather vs. down) and construction effects on thickness and resilience.
