Overview
ISO 23537-2:2023 - "Requirements for sleeping bags - Part 2: Fabric and material properties" defines fabric, filling and labelling requirements for adult-sized sleeping bags used in sports and leisure. It sets test methods, measurement tolerances and minimum performance levels for shell and lining fabrics, filling materials (down/feathers or man-made fills) and finished articles. The standard excludes military, extreme-climate expedition bags and sleeping bags for children or babies.
Key topics and technical requirements
The standard focuses on measurable material and product properties and references internationally recognized test methods (EN and ISO standards). Key requirements include:
Applications and who uses it
ISO 23537‑2:2023 is intended for:
- Sleeping bag manufacturers - design validation, material selection and quality control.
- Test laboratories - performing standardized tests and issuing compliant test reports.
- Retailers and procurement - verifying product claims and labelling before sale.
- Product developers and R&D teams - ensuring materials meet durability, hygiene and aesthetic performance targets.
- Standards and compliance officers - documenting conformity and consumer information.
Practical benefits include consistent product quality, reliable consumer labelling, reduced returns and clearer procurement specifications.
