Overview
EN ISO 15791-1:2013 / ISO 15791-1:2014 - "Plastics - Development and use of intermediate-scale fire tests for plastics products - Part 1: General guidance" provides a framework for developing and using intermediate‑scale fire tests for products made of or containing plastics. The standard explains how to identify realistic fire scenarios, define end‑use conditions, and design intermediate‑scale tests that are relevant to a product’s intended application. It supersedes the 2004 edition and aligns CEN and ISO guidance for Europe and internationally.
Key topics and technical requirements
- Scope and purpose: Framework guidance for creation and application of intermediate‑scale fire tests to evaluate product fire performance.
- Terminology and references: Uses definitions from ISO 13943 (Fire safety - Vocabulary) and defines key terms such as fire scenario, test specimen, and intermediate‑scale test.
- Materials and product types: Classification of plastics (thermoplastics, thermosets, foams, elastomers, composites) and identification of semi‑finished and finished products that often require intermediate‑scale testing.
- Fire scenarios: Structured approach to identify and describe ignition, fire growth and large‑room fire scenarios to ensure tests reflect realistic hazards.
- Ignition source characteristics: Guidance on selecting thermal/ignition sources representative of plausible end‑use events.
- Design requirements for tests: Principles to ensure intermediate‑scale tests are representative of product behavior in service (design, environment, mounting, and geometry considerations).
- Guidance on test development and reporting: Best practices for test configuration, data to record and contents of test reports.
- Examples of intermediate‑scale tests: Reference to established methods such as IEC 61034-2, ISO 5658-4, ISO 14696 (ICAL), EN 13823 (SBI), ISO 24473 and ISO 21367.
Practical applications
- Developing and validating intermediate‑scale fire tests during product development and certification.
- Selecting representative test scenarios for furniture, electrical housings, roofing sheets, pipes, ventilation ducts, container and waste receptacles, foamed components and composite laminates.
- Supporting regulatory compliance, quality control, comparative ranking and pre‑selection of materials or designs based on realistic fire behavior.
- Informing safety engineering decisions about material selection, product design and installation practices.
Who should use this standard
- Test laboratories and fire‑testing professionals
- Plastics manufacturers and product designers
- Regulatory authorities and certification bodies
- Fire safety engineers and standards developers
- Quality assurance teams performing comparative or developmental testing
