Overview
EN ISO 3582:2000/A1:2007 (CEN) specifies a laboratory method for assessing the horizontal burning characteristics of small specimens of flexible cellular polymeric materials (soft polymeric foams) when subjected to a small flame. Amendment 1 (2007) updates the original ISO 3582:2000 text and clarifies conditioning and testing time requirements. The standard is used to evaluate ignitability and burning behaviour of cellular polymeric materials in a controlled horizontal test configuration.
Key Topics and Requirements
- Test focus: Laboratory assessment of horizontal burning characteristics of small foam specimens exposed to a small flame (ignitability and burning behaviour).
- Conditioning requirements (amendment):
- Materials shall not be tested less than 72 hours after manufacture, unless it is demonstrated that mean results at 16 h or 48 h do not differ by more than ±10% from those at 72 h. If demonstrated, testing may be performed at 16 h or 48 h respectively.
- Conditioning can be the final part of, or the whole period following manufacture; for quality-control tests, specimen removal and test conditioning may be shortened (specimens taken as early as 12 h after manufacture and conditioned for as little as 6 h) in specified atmospheres.
- Editorial change: Removal of the date suffix from the ISO 1923 reference (after Clause 2).
- Standards governance: Amendment A1 was approved by CEN and adopted as EN ISO 3582:2000/A1:2007 without modification; produced by ISO/TC 45 and CEN/TC 249.
Applications
- Product safety testing and compliance for foam-based products such as furniture, bedding, upholstery, automotive interiors, packaging and insulation.
- Research and development to compare material formulations and flame-retardant treatments.
- Quality control in manufacturing to monitor batch-to-batch variation in ignitability and burn performance.
- Fire-safety engineering and regulatory submissions where horizontal small-flame flammability data are required.
Who Would Use This Standard
- Material and product manufacturers (polyurethane, latex, polyethylene foams)
- Independent test laboratories and certification bodies
- Fire safety engineers and compliance officers
- R&D teams developing flame-retardant foams or safer product designs
- National standards bodies and regulators implementing EN/CEN requirements
