(Amendment)Fire resistance tests for service installations - Part 3: Penetration seals
Fire resistance tests for service installations - Part 3: Penetration seals
This part of the EN 1366 series specifies a method of test and criteria for the evaluation (including field of direct application rules) of the ability of a penetration seal to maintain the fire resistance of a separating element at the position at which it has been penetrated by a service or services. Penetration seals used to seal gaps around chimneys, air ventilation systems, fire rated ventilation ducts, fire rated service ducts, shafts and smoke extraction ducts as well as combined penetration seals are excluded from this part of the EN 1366 series.
NOTE EN 15882-5 [6] deals with penetration seals including ducts and dampers.
Supporting constructions are used in this part of the EN 1366 series to represent separating elements such as walls or floors. These simulate the interaction between the test specimen and the separating element into which the sealing system is to be installed in practice.
This part of the EN 1366 series is intended to be used in conjunction with EN 1363 1.
The purpose of a test described in this part of the EN 1366 series is to assess the integrity and insulation performance of the penetration seal, of the penetrating service or services and of the separating element in the surrounding area of the penetration seal.
No information can be implied by the test concerning the influence of the inclusion of such penetrations and penetration seals on the loadbearing capacity of the separating element.
It is assumed that in each case the lintel above a penetration seal in the wall is designed in hot and cold state in a way that it does not apply any additional vertical load on the penetration seal.
It is not the intention of this test to provide quantitative information on the rate of leakage of smoke and/or hot gases or on the transmission or generation of fumes. Such phenomena are only noted in the test report in describing the general behaviour of test specimens during the test.
Tests in accordance with this part of the EN 1366 series are not intended to supply any information on the ability of the penetration seal to withstand stress caused by movements or displacements of the penetrating services.
The risk of spread of fire downwards caused by burning material, which drips e.g. through a pipe downwards to floors below, is at present excluded from this document.
Tests in accordance with this part of the EN 1366 series do not address any risks associated with leakage of dangerous liquids or gases caused by failure of pipes in case of fire.
Tests in accordance with this part of the EN 1366 series of pipe penetration seals for pipes of pneumatic dispatch systems, pressurized air systems, etc. simulate a situation where the systems are shut off in case of fire.
Explanatory notes to this test method are given in Annex H.
All values given without tolerances in this document are nominal ones unless otherwise specified.
All pipe diameters are outside diameters unless otherwise specified.

Overview
EN 1366-3:2021/FprA1 is a European standard published by CEN under the series EN 1366, focusing specifically on fire resistance tests for service installations, with Part 3 dedicated to penetration seals. This standard outlines testing methods and performance criteria used to evaluate the ability of penetration seals to maintain the fire resistance integrity of separating elements such as walls and floors that have been penetrated by services (e.g., cables, pipes).
The latest amendment (FprA1) provides updates on testing protocols, orientation applicability, and technical specifications to enhance accuracy and relevance in assessing fire resistance of penetration seals. The standard excludes penetration seals around chimneys, ventilation systems, fire-rated ducts, and shafts, which are covered by other standards like EN 15882-5.
Key Topics
Fire Resistance Testing Methodology: EN 1366-3:2021/FprA1 specifies standardized test setups using supporting constructions to simulate real-life separating elements. It assesses the integrity and insulation performance of penetration seals during fire exposure.
Scope of Services Covered: The standard applies to penetration seals sealing gaps around services such as cables and pipes but excludes specific ducts and chimney penetrations.
Evaluation Criteria: Testing ensures seals prevent fire and heat transmission through service penetrations, maintaining the fire resistance rating of the tested separating element. It does not test loadbearing capacity or resistance to mechanical stresses caused by movement.
Orientation and Installation: Test results apply to walls or floors only in the orientation tested, subject to any deviating rules specified. Installation assumptions include lintel design ensuring no additional vertical loads impact the penetration seal.
Limitations: The test does not measure smoke or gas leakage rates, or risks from dripping burning material or hazardous liquid/gas leaks from failed pipes during fire.
Related Test References: EN 1363-1 is used in conjunction for overarching fire resistance testing. Notes and explanatory details are provided in Annex H of the standard.
Recent Amendments: Updates include clarifications on orientation rules, modifications to cable and pipe configurations, and enhanced definitions for service arrangements and test procedures.
Applications
EN 1366-3:2021/FprA1 is essential for manufacturers, installers, fire safety engineers, and regulators involved in:
Fire safety assessment of building service installations: Ensuring penetration seals used around electrical conduits, plumbing, and other technical installations maintain fire compartmentation.
Certification and Product Testing: Guiding labs and certification bodies to perform consistent, reliable fire resistance tests on penetration sealing systems.
Design and Construction Compliance: Assisting architects and engineers in selecting tested penetration sealing products that comply with regional fire safety regulations.
Quality Control: Enabling manufacturers to verify seal performance during product development and production phases.
Risk Mitigation: Supporting building code adherence to reduce fire spread risks via service penetrations in walls and floors.
Related Standards
EN 1366-1 & EN 1366-2: Cover fire resistance tests for ducts and fire dampers, complementing the focus on service penetrations.
EN 15882-5: Addresses penetration seals including ducts and dampers, excluded from EN 1366-3 scope.
EN 1363-1: Provides general fire resistance test methods applicable to EN 1366 series.
National Standards: Many European countries adopt EN 1366-3 with national amendments or supplements.
Other Fire Safety Standards: EN 13501 series for fire classification of construction products and elements, integrated with EN 1366-3 testing outcomes.
By adhering to EN 1366-3:2021/FprA1, professionals ensure that penetration seals reliably maintain fire compartment integrity, improving building fire safety and compliance with European fire protection legislations. The standard’s comprehensive testing framework supports robust evaluation of penetration seal system effectiveness under realistic fire conditions.
