EN 15882-1:2011+A1:2017
(Main + Amendment)Extended application of results from fire resistance tests for service installations - Part 1: Ducts
General Information
- Abstract
This European Standard identifies parameters that affect the fire resistance of ducts for ventilation purposes. It also identifies the factors that need to be considered when deciding whether, or by how much a parameter can be extended either positively or negatively when contemplating the fire resistance on an untested variation in the construction.
This European Standard, where applicable, gives guidance on additional tests that are needed to extend the field of application.
The European Standard gives the principles behind how a conclusion on the influence of specific parameters/constructional details relating to the relevant criteria (E, I, S) can be achieved.
This European Standard only applies to ducts tested to EN 1366 1. Duct sections for use other than in fire resisting heating, ventilation and air conditioning (HVAC) systems are not covered by this European Standard. It does not cover ducts used for smoke control which are tested in accordance with EN 1366 8 or EN 1366 9.

Overview
EN 15882-1:2011+A1:2017 - Extended application of results from fire resistance tests for service installations - Part 1: Ducts (CEN) provides a structured method to extend fire resistance test results from tested ventilation ducts to untested variations of the same duct construction. The standard identifies the parameters that influence fire resistance of ducts for ventilation purposes and gives guidance on when additional tests are required to support an extended field of application.
Key topics and requirements
- Scope limitation: Applies only to ducts tested to EN 1366‑1 (fire resistance tests for service installations - ducts). It does not cover smoke-control ducts (EN 1366‑8 / EN 1366‑9) or duct sections used outside HVAC fire‑resisting systems.
- Performance criteria: Focuses on the relevant criteria E (integrity), I (insulation) and S (smoke leakage) as used for duct classification in EN 13501‑3.
- Critical parameters: Lists and analyses factors affecting fire resistance, such as:
- Orientation (vertical/horizontal), shape and cross‑section changes (rectangular/circular)
- Wall/floor thickness and type, protective material type and thickness
- Pressure variations (positive/negative differential - e.g. >300 Pa / 500 Pa thresholds referenced)
- Supports, hangers, anchors, spacing between supports, length between flanges/spigots
- Joints, access panels, compensators, integrated components (fans, silencers), and combustible materials inside ducts
- Methodology: Requires systematic evaluation of each parameter (often in tabular form) to determine whether a proposed variation will maintain, reduce or require additional testing to confirm the original classification.
- Additional testing & assessment: Where parameter changes could adversely affect E/I/S performance, the standard gives principles for required additional tests, maximum dimensions eligible for classification extension, and how to document an extended application report.
Practical applications and users
This standard is used by:
- Manufacturers of fire‑resisting ventilation ducts and fire‑protected steel ducts to justify variations without full retesting.
- Fire testing laboratories and certification bodies preparing extended application assessments or classification reports.
- Fire safety engineers, HVAC designers and consultants specifying ducts for fire compartmentation and performance-based designs.
- Regulatory authorities and specifiers who evaluate equivalence of untested duct variants against tested reference products.
Practical benefits include reduced need for full-scale retesting, clear justification for acceptable construction variations, and a transparent route to maintain product classifications for fire‑resisting ducts.
