Overview
EN ISO 1182:2020 - Reaction to fire tests for products: Non‑combustibility test (ISO 1182:2020) defines a standardized laboratory method to determine the non‑combustibility performance of building materials. It applies to homogeneous products and substantial components of non‑homogeneous products exposed to controlled furnace conditions (≈750 °C). The document is published by CEN as EN ISO 1182:2020 and replaces the 2010 edition. Information on the precision of the method is provided in Annex A.
Key topics and technical requirements
- Scope and definitions: clear definitions for product, material, homogeneous/non‑homogeneous products, and substantial components (mass/unit area and thickness criteria).
- Apparatus and furnace design: specifies required test apparatus capable of producing the required thermal environment; typical furnace designs are illustrated in Annex B.
- Specimen preparation and conditioning: rules for specimen size, number, preparation and environmental conditioning prior to testing (see EN 13238 for conditioning guidance).
- Instrumentation and thermocouples: requirements for thermocouples (including a second furnace thermocouple introduced in this edition) and calibration procedures following IEC tolerances.
- Calibration and test procedure: procedures for furnace wall and internal temperature calibration, furnace stabilization, and test frequency to ensure reproducible conditions.
- Measurements and results: recording of mass loss, sustained flaming, and temperature rise; criteria for sustained flaming (≥5 s) and guidance on observations to include in the test report.
- Reporting and precision: required test report content and precision data for method repeatability/reproducibility (Annex A).
Practical applications and users
EN ISO 1182:2020 is used to support product classification, specification and regulatory compliance in building and construction sectors. Typical users include:
- Materials manufacturers seeking non‑combustibility verification for product claims.
- Independent test laboratories conducting reaction‑to‑fire testing.
- Fire safety engineers and consultants assessing material behaviour under high temperatures.
- Architects, specifiers and contractors selecting compliant materials for fire‑sensitive applications.
- Regulators and certification bodies referencing a harmonized test method for approvals and building codes.
This test is particularly relevant where materials need to demonstrate they produce minimal heat and flame under severe thermal exposure.
