Overview
ISO 12952-1:2010 specifies a laboratory test method to assess the ignitability of bedding items when exposed to a smouldering cigarette. It applies to items normally placed on a mattress - for example mattress covers, underlays, sheets, blankets, electric blankets, quilts/duvets, pillows and pillowcases - but does not apply to mattresses, bed bases or mattress pads. The standard defines test setup, conditioning, ignition criteria and reporting to evaluate whether a bedding item will support progressive smouldering or flaming initiated by a cigarette.
Key topics and technical requirements
- Scope and purpose: Test method for smouldering cigarette ignition of bedding items; intended for assessment under specified laboratory conditions (not a full fire-hazard evaluation).
- Ignition criteria:
- Progressive smouldering: includes escalating combustion requiring forcible extinction, smouldering until essentially consumed after 1 hour, detectable smoke/heat/glowing after 1 hour, or evidence of active smouldering on final examination.
- Flaming ignition: any occurrence of flames initiated by a smouldering cigarette.
- Ignition source: Un‑tipped cylindrical cigarette with specified dimensions (length 68 ± 2 mm; diameter 8.0 ± 0.5 mm; mass 0.95 ± 0.10 g) and smouldering rate (8 ± 2 min per 40 mm).
- Apparatus and substrate:
- Test rig: open‑mesh platform (example 450 mm × 450 mm) placed in a controlled test enclosure.
- Testing substrate: mineral‑wool fibre pad simulating a mattress, thickness (25 ± 5) mm, thermal conductivity 0.04 W/m·K.
- Specimen preparation:
- Representative specimens including construction details and potential ignition‑promoting features (piping, trims, embroidery) - additional cigarettes placed at such features.
- Size guidance for flat materials, folded items, and pillows/bolsters to ensure reproducibility.
- Cleansing and conditioning:
- Bedding items are typically washed or dry‑cleaned five times per ISO 6330 / ISO 3175 / ISO 10528 as appropriate; single‑use products tested as received.
- Conditioning: 72 h at (23 ± 2) °C and (50 ± 4) % RH; test in draft‑free environment 10–30 °C, 15–80 % RH.
- Health & safety: Tests pose significant risk - use fume control, firefighting measures and suitable PPE; extinguishing smouldering specimens may require immersion or sealed enclosures.
Applications and users
ISO 12952-1:2010 is used by:
- Textile and bedding manufacturers for product design, safety verification and claims.
- Independent test laboratories conducting flammability testing.
- Product safety engineers, compliance teams and procurement specialists assessing bedding ignitability risk.
- Regulators and standards bodies as part of conformity and labeling schemes.
Practical applications include pre‑production testing, safety assessment of fillings and finishes, and evaluation of design features (seams, trims) that may affect cigarette ignitability.
Related standards
- ISO 12952-2 (Ignition source: match‑flame equivalent) - complements Part 1 by addressing small open‑flame ignition.
- ISO 6330, ISO 3175, ISO 10528 - referenced for laundering/dry‑cleaning procedures used before testing.
