Overview
EN ISO 23537-2:2023 (ISO 23537-2:2023) specifies the fabric and material properties and labelling provisions for adult-sized sleeping bags intended for sports and leisure. It is part of the ISO 23537 series (thermal and material requirements separated) and supersedes EN ISO 23537-2:2016. The standard excludes sleeping bags for military use, extreme-climate expeditions, and those for children or babies.
Key topics and technical requirements
The standard defines required test methods and acceptance criteria for shell, lining and filling materials. Major technical topics include:
-
Down proofness
- Shell/lining tested per EN 12132-1. Maximum of 10 feather/down fibres counted per fabric/fabric combination.
-
Synthetic-fibre proofness
- Tested per EN 15586. Maximum of 30 synthetic fibres protruding per cushion.
-
Mechanical properties
- Abrasion resistance: Tested using ISO 12947-1/2 (Martindale). Shell fabrics shall withstand ≥ 20 000 test cycles.
- Tear force: Tested using ISO 13937-1 (Elmendorf). Shell and lining fabrics shall have tear force ≥ 10 N.
- Colour fastness:
- Rubbing (wet/dry) per ISO 105-X12 with staining grade ≥ (3-4) (ISO 105-A03).
- Washing per ISO 105-C06 at care-label temperature with staining and colour change grade ≥ 4 (ISO 105-A03).
- Light fastness referenced to ISO 105-B02 and perspiration to ISO 105-E04 where applicable.
-
Filling material and finished article checks
- Requirements reference EN standards for filling power, hygiene, composition labelling, mass and volume under load (e.g., EN 12130, EN 12132-1, EN 12934, EN 12935, EN 13088, EN 13538-3).
-
Labelling and consumer information
- Clause 6–7 set out marking, mandatory and optional information supplied to consumers (materials, care instructions, filling composition, dimensions, mass).
Applications and users
EN ISO 23537-2:2023 is used by:
- Sleeping bag manufacturers to design and verify material performance and ensure compliance.
- Textile and product test laboratories for standardized test methods (ISO/EN referenced tests).
- Retailers and buyers to evaluate product claims and labelling accuracy.
- Procurement and safety officers specifying performance requirements for leisure and camping equipment.
- Standards committees and product certifiers aligning thermal (ISO 23537-1) and material tests.
Related standards
Key normative references integrated in EN ISO 23537-2:2023 include:
- ISO 12947-1/2, ISO 13937-1, ISO 105 series (A03, B02, C06, E04, X12)
- EN 12130, EN 12132-1, EN 12934, EN 12935, EN 13088, EN 13538-3, EN 15586, EN 29073-1
This standard is essential when specifying or assessing sleeping bag material durability, down containment, colour fastness, and consumer labelling for sports and leisure products.
